A client with dysphagia is being prepared for discharge. Which outcome indicates that the client is ready for discharge? a) The client is free from esophagitis and achalasia. b) The client reports diminished duodenal inflammation. c) The client has normal gastric structures. d) The client doesn't exhibit rectal tenesmus.
answer
A) The client is free from esophagitis and achalasia. Dysphagia may be the reason why a client with esophagitis or achalasia seeks treatment. Therefore, when the client is free of esophagitis or achalasia, he is ready for discharge. Dysphagia isn't associated with rectal tenesmus, duodenal inflammation, or abnormal gastric structures.
question
When a central venous catheter dressing becomes moist or loose, what should a nurse do first? a) Notify the physician. b) Remove the dressing, clean the site, and apply a new dressing. c) Remove the catheter, check for catheter integrity, and send the tip for culture. d) Draw a circle around the moist spot and note the date and time.
answer
B) Remove dressing, clean the site, and apply a new dressing. A nurse maintaining a central venous catheter should change the dressing every 72 hours or when it becomes soiled, moist, or loose. After removing the soiled dressing, the nurse should use sterile technique to clean around the site in accordance with facility policy. After the cleaning solution has dried, the nurse should cover the site with a transparent semipermeable dressing. A nurse who notes drainage on a wound dressing should draw a circle around the moist spot and note the date and time. She should notify the physician if she observes any catheter-related complications. Only a nurse with the appropriate qualifications may remove a central venous catheter, and a moist or loose dressing isn't a reason to remove the catheter.
question
Which of the following represents the medication classification of a proton (gastric acid) pump inhibitor? a) Famotidine (Pepcid) b) Metronidazole (Flagyl) c) Omeprazole (Prilosec) d) Sucralfate (Carafate)
answer
C) Omeprazole Omeprazole decreases gastric acid by slowing the hydrogen-potassium adenosine triphosphatase pump on the surface of the parietal cells. Sucralfate is a cytoprotective drug. Famotidine is a histamine-2 receptor antagonist. Metronidazole is an antibiotic, specifically an amebicide.
question
A client receives a local anesthetic to suppress the gag reflex for a diagnostic procedure of the upper GI tract. Which of the following nursing interventions is advised for this patient? a) The client should be monitored for any breathing related disorder or discomforts b) The client should not be given any food and fluids until the gag reflex returns c) The client should be monitored for cramping or abdominal distention d) The client's fluid output should be measured for at least 24 hours after the procedure
answer
B) The client should not be given any food and fluids until the gag reflex returns. For a client receiving a local anesthetic that suppresses the gag reflex, the nurse is advised to withhold food and fluids until the reflex returns.
question
A nurse is caring for a client who underwent a subtotal gastrectomy. To manage dumping syndrome, the nurse should advise the client to: a) restrict fluid intake to 1 qt (1,000 ml)/day. b) drink liquids only between meals. c) don't drink liquids 2 hours before meals. d) drink liquids only with meals.
answer
B) Drink liquids only between meals. A client who experiences dumping syndrome after a subtotal gastrectomy should be advised to ingest liquids between meals rather than with meals. Taking fluids between meals allows for adequate hydration, reduces the amount of bulk ingested with meals, and aids in the prevention of rapid gastric emptying. There is no need to restrict the amount of fluids, just the time when the client drinks fluids. Drinking liquids with meals increases the risk of dumping syndrome by increasing the amount of bulk and stimulating rapid gastric emptying. Small amounts of water are allowable before meals.
question
A patient who has undergone colostomy surgery is experiencing constipation. Which of the following interventions should a nurse consider for such a patient? a) Instruct the patient to keep a record of food intake b) Instruct the patient to avoid prune or apple juice c) Suggest fluid intake of at least 2 L per day d) Assist the patient regarding the correct diet or to minimize food intake
answer
C) Suggest fluid intake of at least 2 L per day For constipation the nurse should suggest a fluid intake of at least 2L per day. The nurse should also offer prune or apple juice because they promote elimination. The nurse should encourage the patient to eat regular meals. Dieting or fasting can decrease stool volume and slow elimination. The nurse should instruct the patient to keep a record of food intake in case of diarrhea because this helps identify specific foods that irritate the GI tract.
question
A patient scheduled to undergo an abdominal ultrasonography is advised to do which of the following? a) Do not undertake any strenuous exercise for 24 hours before the test b) Restrict eating of solid food for 6 to 8 hours before the test. c) Avoid exposure to sunlight for at least 6 to 8 hours before the test d) Do not consume anything sweet for 24 hours before the test
answer
B) Avoid eating of solid food for 6 to 8 hours before the test. For a patient who is scheduled to undergo an abdominal ultrasonography, the patient should restrict herself from solid food for 6 to 8 hours to avoid having images of her test obscured with gas and intestinal contents. Ultrasonography records the reflection of sound waves. Strenuous exercises, the consumption of sweets, and exposure to sunlight do not affect the results of the test in any way.
question
A client is admitted with a diagnosis of acute appendicitis. When assessing the abdomen, the nurse would expect to find rebound tenderness at which location? a) Left lower quadrant b) Left upper quadrant c) Right upper quadrant d) Right lower quadrant
answer
D) Right lower quadrant The pain of acute appendicitis localizes in the right lower quadrant (RLQ) at McBurney's point, an area midway between the umbilicus and the right iliac crest. Often, the pain is worse when manual pressure near the region is suddenly released, a condition called rebound tenderness.
question
A client with cholelithiasis has a gallstone lodged in the common bile duct. When assessing this client, the nurse expects to note: a) black, tarry stools. b) circumoral pallor. c) light amber urine. d) yellow sclerae.
answer
D) Yellow sclerae Yellow sclerae are an early sign of jaundice, which occurs when the common bile duct is obstructed. Urine normally is light amber. Circumoral pallor and black, tarry stools don't occur in common bile duct obstruction; they are signs of hypoxia and GI bleeding, respectively.
question
A client with acute liver failure exhibits confusion, a declining level of consciousness, and slowed respirations. The nurse finds him very difficult to arouse. The diagnostic information which best explains the client's behavior is: a) elevated liver enzymes and low serum protein level. b) subnormal clotting factors and platelet count. c) elevated blood urea nitrogen and creatinine levels and hyperglycemia. d) subnormal serum glucose and elevated serum ammonia levels.
answer
D) Subnormal serum glucose and elevated serum ammonia levels. In acute liver failure, serum ammonia levels increase because the liver can't adequately detoxify the ammonia produced in the GI tract. In addition, serum glucose levels decline because the liver isn't capable of releasing stored glucose. Elevated serum ammonia and subnormal serum glucose levels depress the level of a client's consciousness. Elevated liver enzymes, low serum protein level, subnormal clotting factors and platelet count, elevated blood urea nitrogen and creatine levels, and hyperglycemia aren't as directly related to the client's level of consciousness.
question
Which outcome indicates effective client teaching to prevent constipation? a) The client reports engaging in a regular exercise regimen. b) The client limits water intake to three glasses per day. c) The client verbalizes consumption of low-fiber foods. d) The client maintains a sedentary lifestyle.
answer
A) The client reports engaging in a regular exercise regimen. The client having a regular exercise program indicates effective teaching. A regular exercise regimen promotes peristalsis and contributes to regular bowel elimination patterns. A low-fiber diet, a sedentary lifestyle, and limited water intake would predispose the client to constipation.
question
A client with a gastrojejunostomy is beginning to take solid food. Which finding would lead the nurse to suspect that the client is experiencing dumping syndrome? a) Slowed heart beat b) Hyperglycemia c) Diarrhea d) Dry skin
answer
C) Diarrhea Clients with a gastrojejunostomy are at risk for developing the dumping syndrome when they begin to take solid food. This syndrome produces weakness, dizziness, sweating, palpitations, abdominal cramps, and diarrhea, which result from the rapid emptying (dumping) of large amounts of hypertonic chyme (a liquid mass of partly digested food) into the jejunum. This concentrated solution in the gut draws fluid from the circulating blood into the intestine, causing hypovolemia. The drop in blood pressure can produce syncope. As the syndrome progresses, the sudden appearance of carbohydrates in the jejunum stimulates the pancreas to secrete excessive amounts of insulin, which in turn causes hypoglycemia.
question
A nurse is teaching an elderly client about good bowel habits. Which statement by the client indicates to the nurse that additional teaching is required? a) "I need to drink 2 to 3 liters of fluids every day." b) "I should exercise four times per week." c) "I need to use laxatives regularly to prevent constipation." d) "I should eat a fiber-rich diet with raw, leafy vegetables, unpeeled fruit, and whole grain bread."
answer
C) "I need to use laxatives regularly to prevent constipation." The client requires more teaching if he states that he'll use laxatives regularly to prevent constipation. The nurse should teach this client to gradually eliminate the use of laxatives because using laxatives to promote regular bowel movements may have the opposite effect. A high-fiber diet, ample amounts of fluids, and regular exercise promote good bowel health.
question
A client with inflammatory bowel disease undergoes an ileostomy. On the first day after surgery, the nurse notes that the client's stoma appears dusky. How should the nurse interpret this finding? a) The ostomy bag should be adjusted. b) Blood supply to the stoma has been interrupted. c) An intestinal obstruction has occurred. d) This is a normal finding 1 day after surgery.
answer
B) Blood supply to the stoma has been interrupted. An ileostomy stoma forms as the ileum is brought through the abdominal wall to the surface skin, creating an artificial opening for waste elimination. The stoma should appear cherry red, indicating adequate arterial perfusion. A dusky stoma suggests decreased perfusion. The nurse should interpret this finding as an indication that the stoma's blood supply is interuppted, which may lead to tissue damage or necrosis. A dusky stoma isn't a normal finding 1 day after surgery. Adjusting the ostomy bag wouldn't affect stoma color, which depends on blood supply to the area. An intestinal obstruction also wouldn't change stoma color.
question
A client is scheduled for an esophagogastroduodenoscopy (EGD) to detect lesions in the gastrointestinal tract. The nurse would observe for which of the following while assessing the client during the procedure? a) Signs of perforation b) Gag reflex c) Client's tolerance for pain and discomfort d) Client's ability to retain the barium
answer
C) Client's tolerance for pain and discomfort The nurse has to assess the client's tolerance for pain and discomfort during the procedure. The nurse should assess the signs of perforation and the gag reflex after the procedure of EGD and not during the procedure. Assessing the client's level for retaining barium is important for a diagnostic test that involves the use of barium. EGD does not involve the use of barium.
question
What kind of feeding should be administered to a client who is at the risk of diarrhea due to hypertonic feeding solutions? a) Bolus feeding b) Intermittent feeding c) Cyclic feeding d) Continuous feedings
answer
D) Continuous feedings. Continuous feedings should be administered to a client who is at the risk of diarrhea due to hypertonic feeding solutions.
question
The nurse is preparing to measure the client's abdominal girth as part of the physical examination. At which location would the nurse most likely measure? a) At the lower border of the liver b) In the right upper quadrant c) At the umbilicus d) Just below the last rib
answer
C) At the umbilicus Measurement of abdominal girth is done at the widest point, which is usually the umbilicus. The right upper quadrant, lower border of the liver, or just below the last rib would be inappropriate sites for abdominal girth measurement.
question
A client is diagnosed with megaloblastic anemia caused by vitamin B12 deficiency. The physician begins the client on cyanocobalamin (Betalin-12), 100 mcg I.M. daily. Which substance influences vitamin B12 absorption? a) Hydrochloric acid b) Histamine c) Liver enzyme d) Intrinsic factor
answer
D) Intrinsic factor Vitamin B12 absorption depends on intrinsic factor, which is secreted by parietal cells in the stomach. The vitamin binds with intrinsic factor and is absorbed in the ileum. Hydrochloric acid, histamine, and liver enzymes don't influence vitamin B12 absorption.
question
Patients diagnosed with esophageal varices are at risk for hemorrhagic shock. Which of the following is a sign of potential hypovolemia? a) Hypotension b) Bradycardia c) Warm moist skin d) Polyuria
answer
A) Hypotension Signs of potential hypovolemia include cool, clammy skin, tachycardia, decreased blood pressure, and decreased urine output.
question
The nurse is assessing a client with a bleeding gastric ulcer. When examining the client's stool, which of the following characteristics would the nurse be most likely to find? a) Green color and texture b) Black and tarry appearance c) Clay-like quality d) Bright red blood in stool
answer
B) Black and tarry appearance Black and tarry stools (melena) are a sign of bleeding in the upper gastrointestinal (GI) tract. As the blood moves through the GI system, digestive enzymes turn red blood to black. Bright red blood in the stool is a sign of lower GI bleeding. Green color and texture is a distractor for this question. Clay-like stools are a characteristic of biliary disorders
question
After teaching a group of students about the various organs of the upper gastrointestinal tract and possible disorders, the instructor determines that the teaching was successful when the students identify which of the following structures as possibly being affected? a) Large intestine b) Ileum c) Stomach d) Liver
answer
C) Stomach The upper gastrointestinal (GI) tract begins at the mouth and ends at the jejunum. Therefore, the stomach would be a component of the upper GI tract. The lower GI tract begins at the ileum and ends at the anus. The liver is considered an accessory structure.
question
A nurse is providing care for a client recovering from gastric bypass surgery. During assessment, the client exhibits pallor, perspiration, palpitations, headache, and feelings of warmth, dizziness, and drowsiness. The client reports eating 90 minutes ago. The nurse suspects: a) Peritonitis b) A normal reaction to surgery c) Dehiscence of the surgical wound d) Vasomotor symptoms associated with dumping syndrome
answer
D) Vasomotor symptoms associated with dumping syndrome Early manifestations of dumping syndrome occur 15 to 30 minutes after eating. Signs and symptoms include vertigo, tachycardia, syncope, sweating, pallor, palpitations, diarrhea, nausea, and the desire to lie down. Dehiscence of the surgical wound is characterized by pain and a pulling or popping feeling at the surgical site. Peritonitis presents with a rigid, boardlike abdomen, tenderness, and fever. The client's signs and symptoms aren't a normal reaction to surgery.
question
A nurse is caring for a client with active upper GI bleeding. What is the appropriate diet for this client during the first 24 hours after admission? a) Skim milk b) Nothing by mouth c) Regular diet d) Clear liquids
answer
B) NPO Shock and bleeding must be controlled before oral intake, so the client should receive nothing by mouth. When the bleeding is controlled, the diet is gradually increased, starting with ice chips and then clear liquids. Skim milk shouldn't be given because it increases gastric acid production, which could prolong bleeding. A clear liquid diet is the first diet offered after bleeding and shock are controlled.
question
Which of the following is a protrusion of the intestine through a weakened area in the abdominal wall? a) Tumor b) Adhesion c) Hernia d) Volvulus
answer
C) Hernia A hernia is a protrusion of intestine through a weakened area in the abdominal muscle or wall. A tumor that extends into the intestinal lumen, or a tumor outside the intestine causes pressure on the wall of the intestine. Volvulus occurs when the bowel twists and turns on itself. An adhesion occurs when loops of intestine become adherent to areas that heal slowly or scar after abdominal surgery.
question
A client with a disorder of the oral cavity cannot tolerate tooth brushing or flossing. Which of the following strategies can the nurse employ to assist this client? a) Regularly wipe the outside of the client's mouth to prevent germs from entering. b) Provide the client with an irrigating solution of baking soda and warm water. c) Recommend that the client drink a small glass of alcohol at the end of the day to kill germs. d) Urge the client to regularly rinse the mouth with tap water.
answer
B) Provide the client with an irrigating solution of baking soda and warm water If a client cannot tolerate brushing or flossing, an irrigating solution of 1 tsp of baking soda to 8 oz of warm water, half strength hydrogen peroxide, or normal saline solution is recommended.
question
Which of the following terms is used to refer to intestinal rumbling? a) Diverticulitis b) Tenesmus c) Borborygmus d) Azotorrhea
answer
C) Borborygmus Borborygmus is the intestinal rumbling that accompanies diarrhea. Tenesmus is the term used to refer to ineffectual straining at stool. Azotorrhea is the term used to refer to excess of nitrogenous matter in the feces or urine. Diverticulitis refers to inflammation of a diverticulum from obstruction (by fecal matter) resulting in abscess formation.
question
A nurse is preparing a presentation for a local community group about hepatitis. Which of the following would the nurse include? a) Hepatitis B is transmitted primarily by the oral-fecal route. b) Hepatitis A is frequently spread by sexual contact. c) Hepatitis C increases a person's risk for liver cancer. d) Infection with hepatitis G is similar to hepatitis A.
answer
C) Hep C increases a person's risk for liver cancer Infection with hepatitis C increases the risk of a person developing hepatic (liver) cancer. Hepatitis A is transmitted primarily by the oral-fecal route; hepatitis B is frequently spread by sexual contact and infected blood. Hepatitis E is similar to hepatitis A whereas hepatitis G is similar to hepatitis C.
question
To prevent gastroesophageal reflux in a client with hiatal hernia, the nurse should provide which discharge instruction? a) "Lie down after meals to promote digestion." b) "Avoid coffee and alcoholic beverages." c) "Limit fluid intake with meals." d) "Take antacids with meals."
answer
B) Avoid coffee and alcoholic beverages To prevent reflux of stomach acid into the esophagus, the nurse should advise the client to avoid foods and beverages that increase stomach acid, such as coffee and alcohol. The nurse also should teach the client to avoid lying down after meals, which can aggravate reflux, and to take antacids after eating. The client need not limit fluid intake with meals as long as the fluids aren't gastric irritants.
question
After assessing a client with peritonitis, the nurse most likely would document the client's bowel sounds as: a) Absent. b) High-pitched. c) Mild. d) Hyperactive.
answer
A) Absent Since lack of bowel motility typically accompanies peritonitis, bowel sounds are absent. Therefore, the nurse will not observe mild, high-pitched, or hyperactive bowel sounds.
question
A client has noticed increased incidence of constipation since he broke his ankle and cannot complete his daily three-mile walk. As his home care nurse, you complete your assessment and discuss the potential causes. During your client education session, what do you explain as the mechanical cause of his constipation? a) No known cause b) Ingesting excessive fiber c) Stool remaining in the large intestine too long. d) Drinking excessive water
answer
C) Stool remaining in the large intestine too long Whenever stool remains stationary in the large intestine, moisture continues to be absorbed from the residue. Consequently, retention of stool, for any number of reasons, causes stool to become dry and hard.
question
The most significant complication related to continuous tube feedings is a) an interruption in fat metabolism and lipoprotein synthesis. b) a disturbance in the sequence of intestinal and hepatic metabolism. c) the interruption of GI integrity, d) the potential for aspiration,
answer
D) The potential for aspiration Because the normal swallowing mechanism is bypassed, consideration of the danger of aspiration must be foremost in the mind of the nurse caring for the patient receiving continuous tube feedings. Tube feedings preserve GI integrity by intraluminal delivery of nutrients. Tube feedings preserve the normal sequence of intestinal and hepatic metabolism. Tube feedings maintain fat metabolism and lipoprotein synthesis.
question
The nurse is caring for a client with cirrhosis. Which assessment findings indicate that the client has deficient vitamin K absorption caused by this hepatic disease? a) Dyspnea and fatigue b) Ascites and orthopnea c) Purpura and petechiae d) Gynecomastia and testicular atrophy
answer
C) Purpura and petechiae A hepatic disorder, such as cirrhosis, may disrupt the liver's normal use of vitamin K to produce prothrombin (a clotting factor). Consequently, the nurse should monitor the client for signs of bleeding, including purpura and petechiae. Dyspnea and fatigue suggest anemia. Ascites and orthopnea are unrelated to vitamin K absorption. Gynecomastia and testicular atrophy result from decreased estrogen metabolism by the diseased liver.
question
Which type of jaundice seen in adults is the result of increased destruction of red blood cells? a) Obstructive b) Nonobstructive c) Hepatocellular d) Hemolytic
answer
D) Hemolytic Hemolytic jaundice results because, although the liver is functioning normally, it cannot excrete the bilirubin as quickly as it is formed. Obstructive jaundice is the result of liver disease. Nonobstructive jaundice occurs with hepatitis. Hepatocellular jaundice is the result of liver disease.
question
A client is scheduled for several diagnostic tests to evaluate her gastrointestinal function. After teaching the client about these tests, the nurse determines that the client has understood the teaching when she identifies which test as not requiring the use of a contrast medium? a) Computer tomography b) Small bowel series c) Colonoscopy d) Upper GI series
answer
C) Colonoscopy A colonoscopy is a direct visual examination of the entire large intestine. It does not involve the use of a contrast agent. Contrast medium may be used with a small bowel series, computed tomography, and upper GI series.
question
A nurse is caring for a client who had gastric bypass surgery 2 days ago. Which assessment finding requires immediate intervention? a) The client states he has been passing gas. b) The client states he is nauseated. c) The client's right lower leg is red and swollen. d) The client complains of pain at the surgical site.
answer
C) Client's right lower leg is red and swollen A red, swollen extremity is a possible sign of a thromboembolism, a common complication after gastric surgery because of the fact that the clients are obese and tend to ambulate less than other surgical clients. The nurse should inform the physician of the finding. Pain at the surgical site should be investigated, but the red, swollen leg is a higher priority. It isn't unusual for a client to be nauseated after gastric bypass surgery. The nurse should follow up with the finding, but only after she has notified the physician about the possible thromboembolism. Passing gas is normal and a sign that the client's intestinal system is beginning to mobilize.
question
When bowel sounds are heard about every 15 seconds, the nurse would record that the bowel sounds are a) absent. b) hypoactive. c) normal. d) sluggish.
answer
C) Normal Normal bowel sounds are heard every 5 to 20 seconds. Hypoactive bowel sound is the description given to auscultation of one to two bowel sounds in 2 minutes. Sluggish is not a term a nurse would use to accurately describe bowel sounds. The nurse records that bowel sounds are absent when no sound is heard in 3 to 5 minutes.
question
Why are antacids administered regularly, rather than as needed, in peptic ulcer disease? a) To increase pepsin activity b) To maintain a regular bowel pattern c) To promote client compliance d) To keep gastric pH at 3.0 to 3.5
answer
D) To keep gastric pH at 3.0 to 3.5 To maintain a gastric pH of 3.0 to 3.5 throughout each 24-hour period, regular (not as needed) doses of an antacid are needed to treat peptic ulcer disease. Frequent administration of an antacid tends to decrease client compliance rather than promote it. Antacids don't regulate bowel patterns, and they decrease pepsin activity.
question
A nurse is teaching a group of middle-aged men about peptic ulcers. When discussing risk factors for peptic ulcers, the nurse should mention: a) alcohol abuse and a history of acute renal failure. b) a history of hemorrhoids and smoking. c) a sedentary lifestyle and smoking. d) alcohol abuse and smoking.
answer
D) Alcochol abuse and smoking The nurse should mention that risk factors for peptic (gastric and duodenal) ulcers include alcohol abuse, smoking, and stress. A sedentary lifestyle and a history of hemorrhoids aren't risk factors for peptic ulcers. Chronic renal failure, not acute renal failure, is associated with duodenal ulcers.
question
Crohn's disease is a condition of malabsorption caused by which of the following pathophysiological processes? a) Gastric resection b) Infectious disease c) Inflammation of all layers of intestinal mucosa d) Disaccharidase deficiency
answer
C) Inflammation of all layers of intestinal mucosa Crohn's disease is also known as regional enteritis and can occur anywhere along the GI tract, but most commonly at the distal ileum and in the colon. Infectious disease causes problems such as small bowel bacterial overgrowth leading to malabsorption. Disaccharidase deficiency leads to lactose intolerance. Postoperative malabsorption occurs after gastric or intestinal resection.
question
What are medium-length nasoenteric tubes are used for? a) Aspiration b) Emptying c) Decompression d) Feeding
answer
D) Feeding Placement of the tube must be verified prior to any feeding. A gastric sump and nasoenteric tube are used for gastrointestinal decompression. Nasoenteric tubes are used for feeding. Gastric sump tubes are used to decompress the stomach and keep it empty.
question
Which diagnostic test is used first to evaluate a client with upper GI bleeding? a) Hemoglobin levels and hematocrit (HCT) b) Endoscopy c) Arteriography d) Upper GI series
answer
A) Hemoglobin levels and hematocrit Hemoglobin and HCT are typically performed first in clients with upper GI bleeding to evaluate the extent of blood loss. Endoscopy is then performed to directly visualize the upper GI tract and locate the source of bleeding. An upper GI series, or barium study, usually isn't the diagnostic method of choice, especially in a client with acute active bleeding who's vomiting and unstable. An upper GI series is also less accurate than endoscopy. Although an upper GI series might confirm the presence of a lesion, it wouldn't necessarily reveal whether the lesion is bleeding. Arteriography is an invasive study associated with life-threatening complications and wouldn't be used for an initial evaluation.
question
A client is admitted to the health care facility with a diagnosis of a bleeding gastric ulcer. The nurse expects this client's stools to be: a) black and tarry. b) coffee-ground-like. c) bright red. d) clay-colored.
answer
A) Black and tarry Black, tarry stools are a sign of bleeding high in the GI tract, as from a gastric ulcer, and result from the action of digestive enzymes on the blood. Vomitus associated with upper GI tract bleeding commonly is described as coffee-ground-like. Clay-colored stools are associated with biliary obstruction. Bright red stools indicate lower GI tract bleeding.
question
Blood shed in sufficient quantities into the upper GI tract, produces which color of stool? a) Bright red b) Milky white c) Green d) Tarry-black
answer
D) Tarry-black Blood shed in sufficient quantities into the upper GI tract produces a tarry-black stool. Blood entering the lower portion of the GI tract or passing rapidly through it will appear bright or dark red. A milky white stool is indicative "of" a patient who received barium. A green stool is indicative of a patient who has eaten spinach.
question
Which of the following would be the least important assessment in a patient diagnosed with ascites? a) Measurement of abdominal girth b) Palpation of abdomen for a fluid shift c) Foul-smelling breath d) Weight
answer
C) Foul smelling breath Foul-smelling breath would not be considered an important assessment for this patient. Measurement of abdominal girth, weight, and palpation of the abdomen for a fluid shift are all important assessment parameters for the patient diagnosed with ascites.
question
The patient is on a continuous tube feeding. The tube placement should be checked every a) 24 hours. b) 12 hours. c) hour. d) shift.
answer
D) Shift Each nurse caring for the patient is responsible for verifying that the tube is located in the proper area for continuous feeding. Checking for placement each hour is unnecessary unless the patient is extremely restless or there is basis for rechecking the tube based on other patient activities. Checking for placement every 12 or 24 hours does not meet the standard of care due the patient receiving continuous tube feedings.
question
A nurse is caring for a client newly diagnosed with hepatitis A. Which statement by the client indicates the need for further teaching? a) "I'll wash my hands often." b) "How did this happen? I've been faithful my entire marriage." c) "I'll take all my medications as ordered." d) "I'll be very careful when preparing food for my family."
answer
B) How did this happen? I've been faithful my entire marriage The client requires further teaching if he suggests that he acquired the virus through sexual contact. Hepatitis A is transmitted by the oral-fecal route or through ingested food or liquid that's contaminated with the virus. Hepatitis A is rarely transmitted through sexual contact. Clients with hepatitis A need to take every effort to avoid spreading the virus to other members of their family with precautions such as preparing food carefully, washing hands often, and taking medications as ordered.
question
A client is evaluated for severe pain in the right upper abdominal quadrant, which is accompanied by nausea and vomiting. The physician diagnoses acute cholecystitis and cholelithiasis. For this client, which nursing diagnosis takes top priority? a) Imbalanced nutrition: Less than body requirements related to biliary inflammation b) Anxiety related to unknown outcome of hospitalization c) Deficient knowledge related to prevention of disease recurrence d) Acute pain related to biliary spasms
answer
D) Acute pain related to biliary spasms The chief symptom of cholecystitis is abdominal pain or biliary colic. Typically, the pain is so severe that the client is restless and changes positions frequently to find relief. Therefore, the nursing diagnosis of Acute pain related to biliary spasms takes highest priority. Until the acute pain is relieved, the client can't learn about prevention, may continue to experience anxiety, and can't address nutritional concerns.
question
A client with dysphagia is being prepared for discharge. Which outcome indicates that the client is ready for discharge? a) The client is free from esophagitis and achalasia. b) The client doesn't exhibit rectal tenesmus. c) The client has normal gastric structures. d) The client reports diminished duodenal inflammation.
answer
A) The client is free from esophagitis and achalasia Dysphagia may be the reason why a client with esophagitis or achalasia seeks treatment. Therefore, when the client is free of esophagitis or achalasia, he is ready for discharge. Dysphagia isn't associated with rectal tenesmus, duodenal inflammation, or abnormal gastric structures.
question
Which client requires immediate nursing intervention? The client who: a) complains of epigastric pain after eating. b) complains of anorexia and periumbilical pain. c) presents with ribbonlike stools. d) presents with a rigid, boardlike abdomen.
answer
D) Presents with a rigid, boardlike abdomen A rigid, boardlike abdomen is a sign of peritonitis, a possibly life-threatening condition. Epigastric pain occurring 90 minutes to 3 hours after eating indicates a duodenal ulcer. Anorexia and periumbilical pain are characteristic of appendicitis. Risk of rupture is minimal within the first 24 hours, but increases significantly after 48 hours. A client with a large-bowel obstruction may have ribbonlike stools.
question
A nurse is applying an ostomy appliance to the ileostomy of a client with ulcerative colitis. Which action is appropriate? a) Maintaining wrinkles in the faceplate so it doesn't irritate the skin b) Gently washing the area surrounding the stoma using a facecloth and mild soap c) Scrubbing fecal material from the skin surrounding the stoma d) Cutting the faceplate opening no more than 2? larger than the stoma
answer
B) Gently washing the area surrounding the stoma using a facecloth and mild soap For a client with an ostomy, maintaining skin integrity is a priority. The nurse should gently wash the area surrounding the stoma using a facecloth and mild soap. Scrubbing the area around the stoma can damage the skin and cause bleeding. The faceplate opening should be no more than 1/8? to 1/6? larger than the stoma. This size protects the skin from exposure to irritating fecal material. The nurse can create an adequate seal and prevent leakage of fecal material from under the faceplate by applying a thin layer of skin barrier and smoothing out wrinkles in the faceplate. Eliminating wrinkles in the faceplate also protects the skin surrounding the stoma from pressure.
question
Crohn's disease is a condition of malabsorption caused by which of the following pathophysiological processes? a) Infectious disease b) Gastric resection c) Disaccharidase deficiency d) Inflammation of all layers of intestinal mucosa
answer
D) Inflammation of all layers of intestinal mucosa Crohn's disease is also known as regional enteritis and can occur anywhere along the GI tract, but most commonly at the distal ileum and in the colon. Infectious disease causes problems such as small bowel bacterial overgrowth leading to malabsorption. Disaccharidase deficiency leads to lactose intolerance. Postoperative malabsorption occurs after gastric or intestinal resection.
question
A longitudinal tear or ulceration in the lining of the anal canal is termed a (an) a) hemorrhoid. b) anorectal abscess. c) anal fissure. d) anal fistula.
answer
C) Anal fissure Fissures are usually caused by the trauma of passing a large, firm stool or from persistent tightening of the anal canal secondary to stress or anxiety (leading to constipation). An anorectal abscess is an infection in the pararectal spaces. An anal fistula is a tiny, tubular, fibrous tract that extends into the anal canal from an opening located beside the anus. A hemorrhoid is a dilated portion of vein in the anal canal.
question
Which of the following medications used for the treatment of obesity prevents the reuptake of serotonin and norepinephrine? a) Sibutramine hydrochloride (Meridia) b) Orlistat (Xenical) c) Bupropion hydrochloride (Wellbutrin) d) Fluoxetine hydrochloride (Prozac)
answer
A) Sibutramine hydrochloride (Meridia) Sibutramine hydrochloride (Meridia) inhibits the reuptake of serotonin and norepinephrine. Meridia decreases appetite. Orlistat (Xenical) prevents the absorption of triglycerides. Side effects of Xenical may include increased bowel movements, gas with oily discharge, decreased food absorption, decreased bile flow, and decreased absorption of some vitamins. Bupropion hydrochloride (Wellbutrin) is an antidepressant medication. Fluoxetine hydrochloride (Prozac) has not been approved by the FDA for use in the treatment of obesity.
question
A nurse is caring for a client who is undergoing a diagnostic workup for a suspected GI problem. The client reports gnawing epigastric pain following meals and heartburn. The nurse suspects the client has: a) diverticulitis. b) peptic ulcer disease. c) appendicitis. d) ulcerative colitis.
answer
D) Peptic Ulcer Disease Peptic ulcer disease is characterized by dull, gnawing pain in the midepigastrium or the back that worsens with eating. Ulcerative colitis is characterized by exacerbations and remissions of severe bloody diarrhea. Appendicitis is characterized by epigastric or umbilical pain along with nausea, vomiting, and low-grade fever. Pain caused by diverticulitis is in the left lower quadrant and has a moderate onset. It's accompanied by nausea, vomiting, fever, and chills.
question
A client with acute liver failure exhibits confusion, a declining level of consciousness, and slowed respirations. The nurse finds him very difficult to arouse. The diagnostic information which best explains the client's behavior is: a) subnormal serum glucose and elevated serum ammonia levels. b) subnormal clotting factors and platelet count. c) elevated liver enzymes and low serum protein level. d) elevated blood urea nitrogen and creatinine levels and hyperglycemia.
answer
A) Subnormal serum glucose and elevated serum ammonia levels In acute liver failure, serum ammonia levels increase because the liver can't adequately detoxify the ammonia produced in the GI tract. In addition, serum glucose levels decline because the liver isn't capable of releasing stored glucose. Elevated serum ammonia and subnormal serum glucose levels depress the level of a client's consciousness. Elevated liver enzymes, low serum protein level, subnormal clotting factors and platelet count, elevated blood urea nitrogen and creatine levels, and hyperglycemia aren't as directly related to the client's level of consciousness.
question
Which of the following indicates an overdose of lactulose? a) Hypoactive bowel sounds b) Constipation c) Watery diarrhea d) Fecal impaction
answer
C) Watery diarrhea The patient receiving lactulose is monitored closely for the development of watery diarrheal stool, which indicates a medication overdose.
question
A nurse is teaching a client with malabsorption syndrome about the disorder and its treatment. The client asks which part of the GI tract absorbs food. The nurse tells the client that products of digestion are absorbed mainly in the: a) rectum. b) stomach. c) small intestine. d) large intestine.
answer
C) Small intestine The small intestine absorbs products of digestion, completes food digestion, and secretes hormones that help control the secretion of bile, pancreatic juice, and intestinal secretions. The stomach stores, mixes, and liquefies the food bolus into chyme and controls food passage into the duodenum; it doesn't absorb products of digestion. Although the large intestine completes the absorption of water, chloride, and sodium, it plays no part in absorbing food. The rectum is the portion of the large intestine that forms and expels feces from the body; its functions don't include absorption.
question
Why should total parental nutrition (TPN) be used cautiously in clients with pancreatitis? a) Such clients can digest high-fat foods. b) Such clients are at risk for hepatic encephalopathy. c) Such clients are at risk for gallbladder contraction. d) Such clients cannot tolerate high-glucose concentration.
answer
D) Such clients cannot tolerate high glucose concentration Total parental nutrition (TPN) is used carefully in clients with pancreatitis because some clients cannot tolerate a high-glucose concentration even with insulin coverage. Intake of coffee increases the risk for gallbladder contraction, whereas intake of high protein increases risk for hepatic encephalopathy in clients with cirrhosis. Patients with pancreatitis should not be given high-fat foods because they are difficult to digest.
question
After teaching a group of students about the various organs of the upper gastrointestinal tract and possible disorders, the instructor determines that the teaching was successful when the students identify which of the following structures as possibly being affected? a) Ileum b) Liver c) Large intestine d) Stomach
answer
D) Stomach The upper gastrointestinal (GI) tract begins at the mouth and ends at the jejunum. Therefore, the stomach would be a component of the upper GI tract. The lower GI tract begins at the ileum and ends at the anus. The liver is considered an accessory structure.
question
A group of students are studying for an examination on the gastrointestinal (GI) system and are reviewing the structures of the esophagus and stomach. The students demonstrate understanding of the material when they identify which of the following as the opening between the stomach and duodenum? a) Hypoharyngeal sphincter b) Cardiac sphincter c) Pyloric sphincter d) Ileocecal valve
answer
C) Pyloric Sphincter The pyloric sphincter is the opening between the stomach and duodenum. The cardiac sphincter is the opening between the esophagus and the stomach. The hypopharyngeal sphincter or upper esophageal sphincter prevents food or fluids from re-entering the pharynx. The ileocecal valve is located at the distal end of the small intestine and regulates flow of intestinal contents into the large intestine.
question
Which of the following is the major carbohydrate that tissue cells use as fuel? a) Proteins b) Fats c) Chyme d) Glucose
answer
D) Glucose Glucose is the major carbohydrate that tissue cells use as fuel. Proteins are a source of energy after they are broken down into amino acids and peptides. Chyme stays in the small intestine for 3 to 6 hours, allowing for continued breakdown and absorption of nutrients. Ingested fats become monoglycerides and fatty acids by the process of emulsification.
question
The nurse asks a client to point to where she feels pain. The client asks why this is important. The nurse's best response would be which of the following? a) "This determines the pain medication to be ordered." b) "If the doctor massages over the exact painful area, the pain will disappear." c) "Often the area of pain is referred from another area." d) "The area may determine the severity of the pain."
answer
C) Often the area of pain is referred from another area Pain can be a major symptom of disease. The location and distribution of pain can be referred from a different area. If a client points to an area of pain and has other symptoms associated with a certain disease, this is valuable information for treatment.
question
A client is scheduled for magnetic resonance imaging (MRI). During the client teaching, the nurse will discuss which of the following? a) "The examination will take only 15 minutes." b) "You must be NPO for the day before the examination." c) "Do you experience any claustrophobia?" d) "You must remove all jewelry but can wear your wedding ring."
answer
C) Do you experience any claustrophobia? MRI is a noninvasive technique that uses magnetic fields and radio waves to produce images of the area being studied. Clients must be NPO for 6 to 8 hours before the study and remove all jewelry and other metals. The examination takes 60 to 90 minutes and can induce feelings of claustrophobia, because the scanner is close fitting.
question
A nurse is providing postprocedure instructions for a client who had an esophagogastroduodenoscopy. The nurse should perform which action? a) Tell the client to call back in the morning so she can give him instructions over the phone. b) Review the instructions with the person accompanying the client home. c) Tell the client there aren't specific instructions for after the procedure. d) Give instructions to the client immediately before discharge.
answer
B) Review the instructions with the person accompanying the client home A client who undergoes esophagogastroduodenoscopy receives sedation during the procedure, and his memory becomes impaired. Clients tend not to remember instructions provided after the procedure. The nurse's best course of action is to give the instructions to the person who is accompanying the client home. It isn't appropriate for the nurse to tell the client to call back in the morning for instructions. The client needs to be aware at discharge of potential complications and signs and symptoms to report to the physician.
question
A nurse is preparing a client for a protcosigmoidoscopy. Identify the quadrant on which this diagnostic test will focus. A) RUQ B) RLQ C) LUQ D) LLQ
answer
D) LLQ The sigmoid colon is in the left lower quadrant. Proctosigmoidoscopy is examination of the rectum and sigmoid colon using a rigid endoscope inserted anally about 10 inches.
question
The most common cause of esophageal varices includes which of the following? a) Portal hypertension b) Asterixis c) Jaundice d) Ascites
answer
A) Portal hypertension Esophageal varices are almost always caused by portal hypertension, which results from obstruction of the portal circulation within the damaged liver. Jaundice occurs when the bilirubin concentration in the blood is abnormally elevated. Ascites results from circulatory changes within the diseased liver. Asterixis is an involuntary flapping movement of the hands associated with metabolic liver dysfunction.
question
Which of the follow statements provide accurate information regarding cancer of the colon and rectum? a) There is no hereditary component to colon cancer. b) Cancer of the colon and rectum is the second most common type of internal cancer in the United States. c) Rectal cancer affects more than twice as many people as colon cancer. d) The incidence of colon and rectal cancer decreases with age.
answer
B) Cancer of the colon and rectum is the second most common type of internal cancer in the US Cancer of the colon and rectum is the second most common type of internal cancer in the United States. Colon cancer affects more than twice as many people as does rectal cancer (94,700 for colon, 34,700 for rectum). The incidence increases with age (the incidence is highest in people older than 85). Colon cancer occurrence is higher in people with a family history of colon cancer.
question
Blood shed in sufficient quantities into the upper GI tract, produces which color of stool? a) Tarry-black b) Milky white c) Green d) Bright red
answer
A) Tarry-black Blood shed in sufficient quantities into the upper GI tract produces a tarry-black stool. Blood entering the lower portion of the GI tract or passing rapidly through it will appear bright or dark red. A milky white stool is indicative "of" a patient who received barium. A green stool is indicative of a patient who has eaten spinach.
question
A nurse is receiving report from the emergency room regarding a new client being admitted to the medical-surgical unit with a diagnosis of peptic ulcer disease. The nurse expects the age of the client will be between a) 20 and 30 years b) 15 and 25 years c) 40 and 60 years d) 60 and 80 years
answer
C) 40 to 60 years Peptic ulcer disease occurs with the greatest frequency in people 40 to 60 years old. It is relatively uncommon in women of childbearing age, but it has been observed in children and even in infants.
question
A nurse is interviewing a client about his past medical history. Which preexisting condition may lead the nurse to suspect that a client has colorectal cancer? a) Polyps b) Weight gain c) Hemorrhoids d) Duodenal ulcers
answer
A) Polyps Colorectal polyps are common with colon cancer. Duodenal ulcers and hemorrhoids aren't preexisting conditions of colorectal cancer. Weight loss — not gain — is an indication of colorectal cancer.
question
The nurse observes dry mucous membranes in a client who is receiving tube feedings after an oral surgery. The client also complains of unpleasant tastes and odors. Which of the following measures should be included in the client's plan of care? a) Provide frequent mouth care. b) Keep the feeding formula refrigerated. c) Ensure adequate hydration with additional water. d) Flush the tube with water before adding the feedings.
answer
A) Provide frequent mouth care Frequent mouth care helps to relieve the discomfort from dryness and unpleasant odors and tastes. It can be done with the help of ice chips and analgesic throat lozenges, gargles, or sprays. Adequate hydration is essential. If urine output is less than less than 500 mL/day, formula and additional water can be given as ordered. Keeping the feeding formula refrigerated and unopened until it is ready for use and flushing the tube with water before adding feedings are measures to protect the client from infections.
question
A client with a peptic ulcer is about to begin a therapeutic regimen that includes a bland diet, antacids, and famotidine (Pepcid). Before the client is discharged, the nurse should provide which instruction? a) "Eat three balanced meals every day." b) "Avoid aspirin and products that contain aspirin." c) "Stop taking the drugs when your symptoms subside." d) "Increase your intake of fluids containing caffeine."
answer
B) Avoid aspirin and products that contain aspirin The nurse should instruct the client to avoid aspirin because it's a gastric irritant and should not be taken by clients with peptic ulcer to prevent further erosion of the stomach lining. The client should eat small, frequent meals rather than three large ones. Antacids and ranitidine prevent acid accumulation in the stomach; they should be taken even after symptoms subside. Caffeine should be avoided because it increases acid production in the stomach.
question
The nurse is checking the residual content for a client who is receiving intermittent feedings. Which residual content, if obtained, would lead the nurse to delay the feeding? a) 120 mL b) 60 mL c) 30 mL d) 90 mL
answer
A) 120 mL Feedings typically are delayed if the residual content measures more than 100 mL for intermittent feedings or 10% to 20% of the hourly amount of a continuous feeding. Thus a residual content of 120 mL would require the nurse to delay the feeding.
question
A nurse is preparing a client with Crohn's disease for a barium enema. What should the nurse do the day before the test? a) Encourage plenty of fluids. b) Order a high-fiber diet. c) Serve dairy products. d) Serve the client his usual diet.
answer
A) Encourage plenty of fluids The nurse should encourage plenty of fluids because adequate fluid intake is necessary to avoid dehydration that may be caused by the bowel preparation and to prevent fecal impaction after the procedure. The client may be placed on a low-residue diet 1 to 2 days before the procedure to reduce the contents in the GI tract. Fiber intake is limited in a low-residue diet. Because dairy products leave a residue, they aren't allowed the evening before the test. Clear liquids only are allowed the evening before the test.
question
A 24-year-old athlete is admitted to the trauma unit following a motor-vehicle collision. The client is comatose and has developed ascites as a result of the accident. You are explaining the client's condition to his parents. In your education, what do you indicate is the primary function of the small intestine? a) Digest proteins b) Digest fats c) Absorb nutrients d) Absorb water
answer
C) Absorb nutrients The primary function of the small intestine is to absorb nutrients from the chyme.
question
A physician has ordered a liver biopsy for a client whose condition is deteriorating. Which of the following places the client at high risk due to her altered liver function during the biopsy? a) Low platelet count b) Low hemoglobin c) Decreased prothrombin time d) Low sodium level
answer
A) Low platelet count Certain blood tests provide information about liver function. Prolonged prothrombin time (PT) and low platelet count place the client at high risk for hemorrhage. The client may receive intravenous (IV) administration of vitamin K or infusions of platelets before liver biopsy to reduce the risk of bleeding.
question
When caring for a client with an acute exacerbation of a peptic ulcer, the nurse finds the client doubled up in bed with severe pain to his right shoulder. The intial appropriate action by the nurse is to a) Assess the client's abdomen and vital signs. b) Irrigate the client's NG tube. c) Place the client in the high-Fowler's position. d) Notify the health care provider.
answer
A) Assess the client's abdomen and vital signs Signs and symptoms of perforation includes sudden, severe upper abdominal pain (persisting and increasing in intensity); pain may be referred to the shoulders, especially the right shoulder, because of irritation of the phrenic nerve in the diaphragm. The nurse should assess the vital signs and abdomen prior to notifying the physician. Irrigation of the NG tube should not be performed because the additional fluid may be spilled into the peritoneal cavity, and the client should be placed in a position of comfort, usually on the side with the head slightly elevated.
question
A client with complaints of right lower quadrant pain is admitted to the emergency department. Blood specimens are drawn and sent to the laboratory. Which laboratory finding should be reported to the physician immediately? a) Hematocrit 42% b) Serum potassium 4.2 mEq/L c) Serum sodium 135 mEq/L d) White blood cell (WBC) count 22.8/mm3
answer
D) White blood cell (WBC) count 22.8/mm3 The nurse should report the elevated WBC count. This finding, which is a sign of infection, indicates that the client's appendix might have ruptured. Hematocrit of 42%, serum potassium of 4.2 mEq/L, and serum sodium of 135 mEq/L are within normal limits. Alterations in these levels don't indicate appendicitis.
question
A client is admitted to the healthcare facility suspected of having acute pancreatitis and undergoes laboratory testing. Which of the following would the nurse expect to find? a) Decreased white blood cell count b) Increased serum calcium levels c) Elevated urine amylase levels d) Decreased liver enzyme levels
answer
c) Elevated urine amylase levels Elevated serum and urine amylase, lipase, and liver enzyme levels accompany significant pancreatitis. If the common bile duct is obstructed, the bilirubin level is above normal. Blood glucose levels and white blood cell counts can be elevated. Serum electrolyte levels (calcium, potassium, and magnesium) are low.
question
The nurse recognizes that the patient diagnosed with a duodenal ulcer will likely experience a) weight loss. b) vomiting. c) pain 2 to 3 hours after a meal. d) hemorrhage.
answer
C) Pain 2 to 3 hours after a meal The patient with a gastric ulcer often awakens between 1 to 2 with pain, and ingestion of food brings relief. Vomiting is uncommon in the patient with duodenal ulcer. Hemorrhage is less likely in the patient with duodenal ulcer than the patient with gastric ulcer. The patient with a duodenal ulcer may experience weight gain.
question
A client with diabetes begins to have digestive problems and is told by the physician that they are a complication of the diabetes. Which of the following explanations from the nurse is most accurate? a) Insulin has an adverse effect of constipation. b) The nerve fibers of the intestinal lining are experiencing neuropathy. c) Elevated glucose levels cause bacteria overgrowth in the large intestine. d) The pancreas secretes digestive enzymes.
answer
D) The pancreas secretes digestive enzymes While the pancreas has the well-known function of secreting insulin, it also secretes digestive enzymes. These enzymes include trypsin, amylase, and lipase. If the secretion of these enzymes are affected by a diseased pancreas as foundi with diabetes, the digestive functioning may be impaired.
question
A client with an esophageal stricture is about to undergo esophageal dilatation. As the bougies are passed down the esophagus, the nurse should instruct the client to do which action to minimize the vomiting urge? a) Hold his breath b) Bear down as if having a bowel movement c) Pant like a dog d) Take long, slow breaths
answer
D) Take long, slow breaths During passage of the bougies used to dilate the esophagus, the client should take long, slow breaths to minimize the vomiting urge. Having the client hold the breath, bear down as if having a bowel movement, or pant like a dog is neither required nor helpful.
question
A nursing instructor tells the class that review of oral hygiene is an important component during assessment of the gastrointestinal system. One of the students questions this statement. Which of the following explanations from the nurse educator is most appropriate? a) "Injury to oral mucosa or tooth decay can lead to difficulty in chewing food." b) "Mouth sores are caused by bacteria that can thin the villi of the small intestine." c) "Decaying teeth secrete toxins that decrease the absorption of nutrients." d) "Bad breath will encourage ingestion of fatty foods to mask odor."
answer
A) Injury to the oral mucosa or tooth decay can lead to difficulty in chewing food Poor oral hygiene can result in injury to the oral mucosa, lip, or palate; tooth decay; or loss of teeth. Such problems may lead to disruption in the digestive system. The ability to chew food or even swallow may be hindered.
question
Which of the following terms describes a gastric secretion that combines with vitamin B12 so that it can be absorbed? a) Amylase b) Trypsin c) Pepsin d) Intrinsic factor
answer
D) Intrinsic factor Intrinsic factor, secreted by the gastric mucosa, combines with dietary vitamin B12 so that the vitamin can be absorbed in the ileum. In the absence of intrinsic factor, vitamin B12 cannot be absorbed and pernicious anemia results. Amylase is an enzyme that aids in the digestion of starch. Pepsin, an important enzyme for protein digestion, is the end product of the conversion of pepsinogen from the chief cells. Digestive enzymes secreted by the pancreas include trypsin, which aids in digesting protein.
question
A client presents with complaints of blood in her stools. Upon inspection, the nurse notes streaks of bright red blood visible on the outer surface of formed stool. Which of the following will the nurse further investigate with this client? a) Ingestion of cherry soda b) Ingestion of cocoa c) Presence or history of hemorrhoids d) Recent barium studies
answer
C) Presence or history of hemorrhoids Stool is normally light to dark brown. Blood in the stool can present in various ways and must be investigated. Lower rectal or anal bleeding is suspected if there is streaking of blood on the surface of the stool or blood is noted on toilet tissue.
question
A client is to have an upper GI procedure with barium ingestion and abdominal ultrasonography. While scheduling these diagnostic tests, the nurse must consider which factor? a) The client may eat a light meal before either test. b) Both tests need to be done before breakfast. c) The upper GI should be scheduled before the ultrasonography. d) The ultrasonography should be scheduled before the GI procedure.
answer
d) The ultrasonography should be scheduled before the GI procedure Both an upper GI procedure with barium ingestion and an ultrasonography may be completed on the same day. The ultrasonography test should be completed first, because the barium solution could interfere with the transmission of the sound waves. The ultrasonography test uses sound waves that are passed into internal body structures, and the echoes are recorded as they strike tissues. Fluid in the abdomen prevents transmission of ultrasound.
question
While palpating a client's right upper quadrant (RUQ), the nurse would expect to find which structure? a) Spleen b) Appendix c) Liver d) Sigmoid colon
answer
C) Liver The RUQ contains the liver, gallbladder, duodenum, head of the pancreas, hepatic flexure of the colon, portions of the ascending and transverse colon, and a portion of the right kidney. The sigmoid colon is located in the left lower quadrant; the appendix, in the right lower quadrant; and the spleen, in the left upper quadrant.
question
The nurse is preparing to examine the abdomen of a client complaining of a change in his bowel pattern. The nurse would place the client in which position? a) Lithotomy b) Supine with knees flexed c) Knee-chest d) Left Sim's lateral
answer
B) Supine with knees flexed When examining the abdomen, the client lies supine with his knees flexed. This position assists in relaxing the abdominal muscles. The lithotomy position commonly is used for a female pelvic examination and to examine the rectum. The knee-chest position can be used for a variety of examinations, most commonly the anus and rectum. The left Sim's lateral position may be used to assess the rectum or vagina and to administer an enema.
question
What part of the GI tract begins the digestion of food? a) Stomach b) Mouth c) Duodenum d) Esophagus
answer
B) Mouth Food that contains starch undergoes partial digestion when it mixes with the enzyme salivary amylase, which the salivary glands secrete.
question
A client is scheduled for several diagnostic tests to evaluate her gastrointestinal function. After teaching the client about these tests, the nurse determines that the client has understood the teaching when she identifies which test as not requiring the use of a contrast medium? a) Computer tomography b) Colonoscopy c) Small bowel series d) Upper GI series
answer
B) Colonoscopy A colonoscopy is a direct visual examination of the entire large intestine. It does not involve the use of a contrast agent. Contrast medium may be used with a small bowel series, computed tomography, and upper GI series.
question
A physician plans to send a client home with supplies to complete a hemoccult test on all stools for 3 days. During the client education, the nurse informs the client to avoid which of the following medications while collecting stool for the test? a) ibuprofen (Advil) b) ciprofloxacin (Cipro XR) c) docusate sodium (Colace) d) acetaminophen (Tylenol)
answer
A) Ibprofen (Advil) Fecal occult blood testing (FOBT) is one of the most commonly performed stool tests. FOBT can be done at the bedside, in the physician's office, or at home. The client is taught to avoid aspirin, red meats, nonsteroidal antiinflammatory agents, and horseradish for 72 hours prior to the examination. Advil is an anti-inflammatory drug and should be avoided with FOBT.
question
A client comes into the emergency department with complaints of abdominal pain. Which of the following should the nurse ask first? a) Family history of ruptured appendix b) Characteristics and duration of pain c) Concerns about impending hospital stay d) Medications taken in the last 8 hours
answer
B) Characteristics and duration of pain A focused abdominal assessment begins with a complete history. The nurse must obtain information about abdominal pain. Pain can be a major symptom of gastrointestinal disease. The character, duration, pattern, frequency, location, distribution, and timing of the pain vary but require investigation immediately.
question
A client presented with gastrointestinal bleeding 2 days ago and continues to have problems. The physician has ordered a visualization of the small intestine via a capsule endoscopy. Which of the following will the nurse include in the client education about this procedure? a) "An x-ray machine will use a capsule ray to follow your intestinal tract." b) "You will need to swallow a capsule." c) "The physician will use a scope called a capsule to view your intestine." d) "A capsule will be inserted into your rectum."
answer
B) You will need to swallow a capsule A capsule endoscopy allows for noninvasive visualization of the small intestinal mucosa. The technique consists of the client swallowing a capsule that is embedded with a wireless miniature camera, which is propelled through the intestine by peristalsis. The capsule passes from the rectum in 1 to 2 days.
question
A patient scheduled to undergo an abdominal ultrasonography is advised to do which of the following? a) Restrict eating of solid food for 6 to 8 hours before the test. b) Do not consume anything sweet for 24 hours before the test c) Do not undertake any strenuous exercise for 24 hours before the test d) Avoid exposure to sunlight for at least 6 to 8 hours before the test
answer
A) Restrict eating of solid food for 6 to 8 hours before the test For a patient who is scheduled to undergo an abdominal ultrasonography, the patient should restrict herself from solid food for 6 to 8 hours to avoid having images of her test obscured with gas and intestinal contents. Ultrasonography records the reflection of sound waves. Strenuous exercises, the consumption of sweets, and exposure to sunlight do not affect the results of the test in any way.
question
The nurse is to obtain a stool specimen from a client who reported that he is taking iron supplements. The nurse would expect the stool to be which color? a) Black b) Red c) Dark brown d) Green
answer
A) Black Ingestion of iron can cause the stool to turn black. Meat protein causes stool to appear dark brown. Ingestion of large amounts of spinach may turn stool green while ingestion of carrots and beets may cause stool to turn red.
question
A nurse is assisting with preoperative care for a client who requires an appendectomy. The nurse is aware that the surgery will involve which abdominal quadrant? A) RLQ B) RUQ C) LLQ D) LUQ
answer
A) RLQ The appendix is in the right lower quadrant.
question
The client cannot tolerate oral feedings due to an intestinal obstruction and is NPO. A central line has been inserted, and the client is being started on parenteral nutrition (PN). The nurse performs the following actions while the client receives PN (select all that apply): a) Document intake and output. b) Use clean technique for all catheter dressing changes. c) Weigh the client every day. d) Cover insertion site with a transparent dressing that is changed daily. e) Check blood glucose level every 6 hours.
answer
A) Document intake and output; C) Weigh the client every day; E) Check blood glucose level every 6 hours When a client is receiving PN through a central line, the nurse weighs the client daily, checks blood glucose level every 6 hours, and documents intake and output. These actions are to ensure the client is receiving optimal nutrition. The nurse also performs activities to prevent infection, such as covering the insertion site with a transparent dressing that is changed weekly and/or prn and using sterile technique during catheter site dressing changes.
question
Which of the following is the primary symptom of achalasia? a) Difficulty swallowing b) Pulmonary symptoms c) Chest pain d) Heartburn
answer
A) Difficulty swallowing The primary symptom of achalasia is difficulty in swallowing both liquids and solids. The patient may also report chest pain and heartburn that may or may not be associated with eating. Secondary pulmonary complications may result from aspiration of gastric contents.
question
A nurse enters the room of a client who has returned to the unit after having a radical neck dissection. Which assessment finding requires immediate intervention? a) The client lying in a lateral position, with the head of bed flat b) Foley catheter bag containing 500 ml of amber urine c) Serosanguineous drainage on the dressing d) A piggyback infusion of levofloxacin (Levaquin)
answer
A) The client lying in a lateral position, with the head of bed flat A client who has had neck surgery is at risk for neck swelling. To prevent respiratory complications, the head of the bed should be at least at a 30-degree angle. This position gives the lungs room to expand and decreases swelling by promoting venous and lymphatic drainage. This position also minimizes the risk of aspiration. Serosanguineous drainage on the dressing, a Foley bag containing amber urine, and levofloxacin infusing aren't causes for concern.
question
To ensure patency of central venous line ports, diluted heparin flushes are used in which of the following situations? a) Before drawing blood b) With continuous infusions c) When the line is discontinued d) Daily when not in use
answer
D) Daily when not in use Daily instillation of dilute heparin flush when a port is not in use will maintain the port. Continuous infusion maintains the patency of each port. Heparin flushes are used after each intermittent infusion. Heparin flushes are used after blood drawing in order to prevent clotting of blood within the port. Heparin flush of ports is not necessary if a line is to be discontinued.
question
A client with GERD develops espophagitis. Which diagnostic test would the nurse expect the physician to order to confirm the diagnosis? a) Upper endoscopy with biopsy b) Stool testing for occult blood c) 24-hour esophageal pH monitoring d) Barium swallow
answer
A) Upper endoscopy with biopsy Upper endoscopy with biopsy confirms esophagitis. Barium-swallow would reveal inflammation or stricture formation from chronic esophagitis. Tests of stool may show positive findings of blood. Ambulatory 24-hour esophageal pH monitoring allows for observation of the frequency of reflux episodes and their associated symptoms.
question
Which of the following medications requires the nurse to contact the pharmacist in consultation when the patient receives all oral medications by feeding tube? a) Buccal or sublingual tablets b) Enteric-coated tablets c) Soft gelatin capsules filled with liquid d) Simple compressed tablets
answer
B) Enteric-coated tablets Enteric-coated tablets are meant to be digested in the intestinal tract and may be destroyed by stomach acids. A change in the form of medication is necessary for patients with tube feedings. Simple compressed tablets may be crushed and dissolved in water for patients receiving oral medications by feeding tube. Buccal or sublingual tablets are absorbed by mucous membranes and may be given as intended to the patient undergoing tube feedings. The nurse may make an opening in the capsule and squeeze out contents for administration by feeding tube.
question
A client recovering from gastric bypass surgery accidentally removes the nasogastric tube. It is best for the nurse to a) Notify the surgeon about the tube's removal. b) Reinsert the nasogastric tube to the stomach. c) Document the discontinuation of the nasogastric tube. d) Place the nasogastric tube to the level of the esophagus.
answer
A) Notify the surgeon about the tube's removal If the nasogastric tube is removed accidently in a client who has undergone esophageal or gastric surgery, it is usually replaced by the physician. Care is taken to avoid trauma to the suture line. The nurse will not insert the tube to the esophagus or to the stomach in this situation. The nurse needs to do more than just document its removal. The nurse needs to notify the physician who will make a determination of leaving out or inserting a new nasogastric tube.
question
Paul Cavanagh, a 63-year-old retired teacher, had oral cancer and had extensive surgery to excise the malignancy. While is surgery was deemed successful, it was quite disfiguring and incapacitating. What is essential to Mr. Cavanagh and his family? a) Knowing that everything will work out just fine b) Time to mourn, accept, and adjust to the loss c) Not giving in to anger d) Having a courageous attitude
answer
B) Time to mourn, accept, and adjust to the loss The first time family members or clients see the effects of surgery, the experience usually is traumatic. The nurse needs to promote effective coping and therapeutic grieving at this time. Responses may range from crying or extreme sadness and avoiding contact with others to refusing to talk about the surgery or changes in appearance. Allowing the client time to mourn, accept, and adjust to losses is essential.
question
Initially, which diagnostic should be completed following placement of a NG tube? a) X-ray b) Measurement of tube length c) pH measurement of aspirate d) Visual assessment of aspirate
answer
A) X-ray Instead of auscultation, a combination of three methods is recommended: measurement of tube length, visual assessment of aspirate, and pH measurement of aspirate.
question
A client who is recovering from anesthesia following oral surgery for lip cancer is experiencing difficulty breathing deeply and coughing up secretions. Which of the following measures will help ease the client's discomfort? a) Positioning the client flat on the abdomen or side. b) Keeping the head of the bed elevated. c) Turning the client's head to the side. d) Providing a tracheostomy tray near the bed.
answer
B) Keeping the head of the bed elevated It is essential to position the client with the head of the bed elevated because it is easier for the client to breathe deeply and cough up secretions after recovering from the anesthetic. Positioning the client flat either on the abdomen or side with the head turned to the side will facilitate drainage from the mouth. A tracheostomy tray is kept by the bed for respiratory distress or airway obstruction. When mouth irrigation is carried out, the nurse should turn the client's head to the side to allow the solution to run in gently and flow out.
question
Which of the following is an accurate statement regarding cancer of the esophagus? a) Chronic irritation of the esophagus is a known risk factor. b) It is three times more common in women in the U.S. than men. c) It is seen more frequently in Caucasian Americans than in African Americans. d) It usually occurs in the fourth decade of life.
answer
A) Chronic irritation of the esophagus is a known risk factor In the United States, cancer of the esophagus has been associated with the ingestion of alcohol and the use of tobacco. In the United States, carcinoma of the esophagus occurs more than three times more often in men as in women. It is seen more frequently in African Americans than in Caucasian Americans. It usually occurs in the fifth decade of life
question
Which of the following is the best method for determining nasogastric tube placement? a) Placement of external end of tube under water b) Testing of pH of gastric aspirate c) X-ray d) Observation of gastric aspirate
answer
C) X-ray Radiologic identification of tube placement in the stomach is the most reliable method. Gastric fluid may be grassy green, brown, clear, or odorless while an aspirate from the lungs may be off-white or tan. Hence, checking aspirate is not the best method of determining nasogastric tube placement in the stomach. Gastric pH values are typically lower or more acidic than that of the intestinal or respiratory tract, but not always. Placement of external end of tube under water and watching for air bubbles is not a reliable method for determining nasogastric tube placement in the stomach.
question
Regarding oral cancer, the nurse provides health teaching to inform the patient that a) most oral cancers are painful at the outset. b) blood testing is used to diagnose oral cancer. c) a typical lesion is soft and craterlike. d) many oral cancers produce no symptoms in the early stages.
answer
D) Many oral cancers produce no symptoms in the early stages The most frequent symptom of oral cancer is a painless sore that does not heal. The patient may complain of tenderness, and difficulty with chewing, swallowing, or speaking as the cancer progresses. Biopsy is used to diagnose oral cancer. A typical lesion in oral cancer is a painless hardened ulcer with raised edges.
question
A client has a gastrointestinal tube that enters the stomach through a surgically created opening in the abdominal wall. The nurse documents this as which of the following? a) Jejunostomy tube b) Nasogastric tube c) Orogastric tube d) Gastrostomy tube
answer
D) Gastrostomy tube A gastrostomy tube enters the stomach through a surgically created opening into the abdominal wall. A jejunostomy tube enters jejunum or small intestine through a surgically created opening into the abdominal wall. A nasogastric tube passes through the nose into the stomach via the esophagus. An orogastric tube passes through the mouth into the stomach.
question
The nurse is to obtain a stool specimen from a client who reported that he is taking iron supplements. The nurse would expect the stool to be which color? a) Dark brown b) Red c) Black d) Green
answer
C) Black Ingestion of iron can cause the stool to turn black. Meat protein causes stool to appear dark brown. Ingestion of large amounts of spinach may turn stool green while ingestion of carrots and beets may cause stool to turn red.
question
Which of the following would a nurse expect to assess in a client with peritonitis? a) Decreased pulse rate b) Deep slow respirations c) Hyperactive bowel sounds d) Board-like abdomen
answer
D) Board-like abdomen The client with peritonitis would typically exhibit a rigid, board-like abdomen, with absent bowel sounds, elevated pulse rate, and rapid, shallow respirations.
question
A nurse is applying an ostomy appliance to the ileostomy of a client with ulcerative colitis. Which action is appropriate? a) Maintaining wrinkles in the faceplate so it doesn't irritate the skin b) Scrubbing fecal material from the skin surrounding the stoma c) Cutting the faceplate opening no more than 2? larger than the stoma d) Gently washing the area surrounding the stoma using a facecloth and mild soap
answer
D) Gently washing the area surrounding the stoma using a facecloth and mild soap For a client with an ostomy, maintaining skin integrity is a priority. The nurse should gently wash the area surrounding the stoma using a facecloth and mild soap. Scrubbing the area around the stoma can damage the skin and cause bleeding. The faceplate opening should be no more than 1/8? to 1/6? larger than the stoma. This size protects the skin from exposure to irritating fecal material. The nurse can create an adequate seal and prevent leakage of fecal material from under the faceplate by applying a thin layer of skin barrier and smoothing out wrinkles in the faceplate. Eliminating wrinkles in the faceplate also protects the skin surrounding the stoma from pressure.
question
The nurse is providing care to a client who has had a percutaneous liver biopsy. The nurse would monitor the client for which of the following? a) Intake and output b) Passage of stool c) Return of the gag reflex d) Signs and symptoms of bleeding
answer
D) Signs and symptoms of bleeding A major complication after a liver biopsy is bleeding so it would be important for the nurse to monitor the client for signs and symptoms of bleeding. Return of the gag reflex would be important for the client who had an esophagogastroduodenoscopy to prevent aspiration. Monitoring the passage of stool would be important for a client who had a barium enema or colonoscopy. Monitoring intake and output is a general measure indicated for any client. It is not specific to a liver biopsy.
question
An elderly client asks the nurse how to treat chronic constipation. What is the best recommendation the nurse can make? a) Administer a tap-water enema weekly. b) Take a mild laxative such as magnesium citrate when necessary. c) Take a stool softener such as docusate sodium (Colace) daily. d) Administer a phospho-soda (Fleet) enema when necessary.
answer
C) Take a stool softener such as docusate sodium (Colace) daily Stool softeners taken daily promote absorption of liquid into the stool, creating a softer mass. They may be taken on a daily basis without developing a dependence. Dependence is an adverse effect of daily laxative use. Enemas used daily or on a frequent basis can also lead to dependence of the bowel on an external source of stimulation.
question
Which patient teaching component is important for the nurse to communicate regarding pain management prior to or during diagnostic testing for a disorder of the GI system? a) The patient should not expel gas and test fluids from the bowel when he or she experiences the urge during the procedure. b) The patient should inform the test personnel if he or she experiences pressure or cramping during the instillation of test fluids. c) The patient should take a sedative before the procedure to avoid the possibility of experiencing any discomfort. d) The patient should lie down in a supine position for at least 3 hours before the test to reduce any discomfort during the test.
answer
B) The patient should inform the test personnel if he or she experiences pressure or cramping during instillation of test fluids To ensure that a patient who is to undergo a diagnostic test for a disorder of the gastrointestinal system experiences no or minimal discomfort during the test, the patient should be instructed to inform the test personnel if he or she experiences pressure or cramping during the instillation of test fluids. The test personnel can slow the instillation or take other measures to relieve discomfort. The patient should also be advised to expel gas and test fluids from the bowel when he or she experiences the urge. Ignoring the urge to expel the bowel contents increases pain and discomfort. The patient should be advised not to take any sedative or analgesic before the test, unless prescribed. Lying down in a supine position is not known to have any consequence on the level of discomfort experienced by a patient during a diagnostic test for a GI disorder.
question
Nursing assessment of a client with peritonitis reveals hypotension, tachycardia, and signs and symptoms of dehydration. The nurse also expects to find: a) tenderness and pain in the right upper abdominal quadrant. b) severe abdominal pain with direct palpation or rebound tenderness. c) jaundice and vomiting. d) rectal bleeding and a change in bowel habits.
answer
B) Severe abdominal pain with direct palpation or rebound tenderness Peritonitis decreases intestinal motility and causes intestinal distention. A classic sign of peritonitis is a sudden, diffuse, severe abdominal pain that intensifies in the area of the underlying causative disorder (such as appendicitis, diverticulitis, ulcerative colitis, or a strangulated obstruction). The client may also have rebound tenderness. Tenderness and pain in the right upper abdominal quadrant suggest cholecystitis. Jaundice and vomiting are signs of cirrhosis of the liver. Rectal bleeding or a change in bowel habits may indicate colorectal cancer.
question
A nurse is reviewing the history and physical of a client admitted for a hemorrhoidectomy. Which predisposing condition does the nurse expect to see? a) Constipation b) Hypoglycemia c) Lactic acidosis d) Hyperkalemia
answer
A) Constipation Orthostatic hypertension and other conditions associated with persistently high intra-abdominal pressure (such as pregnancy) can lead to hemorrhoids. The passing of hard stools, not diarrhea, can aggravate hemorrhoids. Diverticulosis has no relationship to hemorrhoids. Rectal bleeding is a symptom of hemorrhoids, not a predisposing condition.
question
After 20 seconds of auscultating for bowel sounds on a client recovering from abdominal surgery, the nurse hears nothing. Which of the following should the nurse do based on the assessment findings? a) Listen longer for the sounds. b) Call the physician to report absent bowel sounds. c) Document that the client is constipated. d) Return in 1 hour and listen again to confirm findings.
answer
A) Listen longer for sounds Auscultation is used to determine the character, location, and frequency of bowel sounds. The frequency and character of sounds are usually heard as clicks and gurgles that occur irregularly and range from 5 to 35 per minutes. Normal sounds are heard about every 5 to 20 seconds, whereas hypoactive sounds can be one or two sounds in 2 minutes. Postoperatively, it is common for sounds to be reduced; therefore, the nurse needs to listen at least 3 to 5 minutes to verify absent or no bowel sounds.
question
A client is being treated for prolonged diarrhea. Which of the following foods should the nurse encourage the client to consume? a) Protein-rich foods b) High-fiber foods c) Potassium-rich foods d) High-fat foods
answer
C) Potassium rich foods The nurse should encourage the client with diarrhea to consume potassium-rich foods. Excessive diarrhea causes severe loss of potassium. The nurse should also instruct the client to avoid high-fiber or fatty foods because these foods stimulate gastrointestinal motility. The intake of protein foods may or may not be appropriate depending on the client's status.
question
A client is admitted to the hospital for diagnostic testing to rule out colorectal cancer. Which intervention should the nurse include on the plan of care? a) Prepare the client for a gastrostomy tube placement. b) Administer morphine (Duramorph PF) routinely, as ordered. c) Test all stools for occult blood. d) Administer topical ointment to the rectal area to decrease bleeding.
answer
C) Test all stools for occult blood Blood in the stools is one of the warning signs of colorectal cancer. The nurse should plan on checking all stools for both frank and occult blood. The blood in the stool is coming from the colon or rectum; administering an ointment wouldn't help decrease the bleeding. Preparing a client for a gastrostomy tube isn't appropriate when diagnosing colorectal cancer. Colorectal cancer is usually painless; administering opioid pain medication isn't needed.
question
A client is admitted with a diagnosis of acute appendicitis. When assessing the abdomen, the nurse would expect to find rebound tenderness at which location? a) Left upper quadrant b) Right lower quadrant c) Left lower quadrant d) Right upper quadrant
answer
B) Right lower quadrant The pain of acute appendicitis localizes in the right lower quadrant (RLQ) at McBurney's point, an area midway between the umbilicus and the right iliac crest. Often, the pain is worse when manual pressure near the region is suddenly released, a condition called rebound tenderness.
question
A nurse is preparing a client with Crohn's disease for a barium enema. What should the nurse do the day before the test? a) Serve dairy products. b) Encourage plenty of fluids. c) Serve the client his usual diet. d) Order a high-fiber diet.
answer
B) Encourage plenty of fluids The nurse should encourage plenty of fluids because adequate fluid intake is necessary to avoid dehydration that may be caused by the bowel preparation and to prevent fecal impaction after the procedure. The client may be placed on a low-residue diet 1 to 2 days before the procedure to reduce the contents in the GI tract. Fiber intake is limited in a low-residue diet. Because dairy products leave a residue, they aren't allowed the evening before the test. Clear liquids only are allowed the evening before the test.
question
A client with appendicitis is experiencing excruciating abdominal pain. An abdominal X-ray film reveals intraperitoneal air. The nurse should prepare the client for: a) colonoscopy. b) surgery. c) nasogastric (NG) tube insertion. d) barium enema.
answer
B) Surgery The client should be prepared for surgery because his signs and symptoms indicate bowel perforation. Appendicitis is the most common cause of bowel perforation in the United States. Because perforation can lead to peritonitis and sepsis, surgery wouldn't be delayed to perform other interventions, such as colonoscopy, NG tube insertion, or a barium enema. These procedures aren't necessary at this point.
question
The nurse is assessing a client for constipation. Which of the following is the first review that the nurse should conduct in order to identify the cause of constipation? Choose the correct option. a) Review the client's current medications b) Review the client's alcohol consumption c) Review the client's usual pattern of elimination d) Review the client's activity levels
answer
C) Review the client's usual pattern of elimination Constipation has many possible reasons; assessing the client's usual pattern of elimination is the first step in identifying the cause.
question
A longitudinal tear or ulceration in the lining of the anal canal is termed a (an) a) anorectal abscess. b) anal fistula. c) anal fissure. d) hemorrhoid.
answer
C) Anal fissure Fissures are usually caused by the trauma of passing a large, firm stool or from persistent tightening of the anal canal secondary to stress or anxiety (leading to constipation). An anorectal abscess is an infection in the pararectal spaces. An anal fistula is a tiny, tubular, fibrous tract that extends into the anal canal from an opening located beside the anus. A hemorrhoid is a dilated portion of vein in the anal canal.
question
A 74-year-old client is on the hospital unit where you practice nursing. She will be undergoing rhinoplasty and you are completing her admission assessment and paperwork. She reports medications she uses on a daily basis, which you record for her chart. Which of her daily medications will result in constipation? a) Acetaminophen b) Laxative c) NSAIDs d) Multivitamin without iron
answer
B) Laxative Constipation may also result from chronic use of laxatives ("cathartic colon") because such use can cause a loss of normal colonic motility and intestinal tone. Laxatives also dull the gastrocolic reflex.
question
Patients with chronic liver dysfunction have problems with insufficient vitamin intake. Which of the following may occur as a result of vitamin C deficiency? a) Beriberi b) Scurvy c) Night blindness d) Hypoprothrombinemia
answer
B) Scurvy Scurvy may result from a vitamin C deficiency. Night blindness, hypoprothrombinemia, and beriberi do not result from a vitamin C deficiency.
question
A client is admitted to the health care facility with abdominal pain, a low-grade fever, abdominal distention, and weight loss. The physician diagnoses acute pancreatitis. What is the primary goal of nursing care for this client? a) Maintaining adequate nutritional status b) Preventing fluid volume overload c) Relieving abdominal pain d) Teaching about the disease and its treatment
answer
C) Relieving abdominal pain The predominant clinical feature of acute pancreatitis is abdominal pain, which usually reaches peak intensity several hours after onset of the illness. Therefore, relieving abdominal pain is the nurse's primary goal. Because acute pancreatitis causes nausea and vomiting, the nurse should try to prevent fluid volume deficit, not overload. The nurse can't help the client achieve adequate nutrition or understand the disease and its treatment until the client is comfortable and no longer in pain.
question
When reviewing the history of a client with pancreatic cancer, the nurse would identify which of the following as a possible risk factor? a) Ingestion of a low-fat diet b) One-time exposure to petrochemicals c) Ingestion of caffeinated coffee d) History of pancreatitis
answer
D) History of pancreatitis Pancreatitis is associated with the development of pancreatic cancer. Other factors that correlate with pancreatic cancer include diabetes mellitus, a high-fat diet, and chronic exposure to carcinogenic substances (i.e., petrochemicals). Although data are inconclusive, a relationship may exist between cigarette smoking and high coffee consumption (especially decaffeinated coffee) and the development of pancreatic carcinoma.
question
A client is diagnosed with a hiatal hernia. Which statement indicates effective client teaching about hiatal hernia and its treatment? a) "I'll lie down immediately after a meal." b) "I'll eat three large meals every day without any food restrictions." c) "I'll eat frequent, small, bland meals that are high in fiber." d) "I'll gradually increase the amount of heavy lifting I do."
answer
C) I'll eat frequent, small, bland meals that are high in fiber In hiatal hernia, the upper portion of the stomach protrudes into the chest when intra-abdominal pressure increases. To minimize intra-abdominal pressure and decrease gastric reflux, the client should eat frequent, small, bland meals that can pass easily through the esophagus. Meals should be high in fiber to prevent constipation and minimize straining on defecation (which may increase intra-abdominal pressure from the Valsalva maneuver). Eating three large meals daily would increase intra-abdominal pressure, possibly worsening the hiatal hernia. The client should avoid spicy foods, alcohol, and tobacco because they increase gastric acidity and promote gastric reflux. To minimize intra-abdominal pressure, the client shouldn't recline after meals, lift heavy objects, or bend.
question
The client is receiving a 25% dextrose solution of parenteral nutrition. The infusion machine is beeping, and the nurse determines the intravenous (IV) bag is empty. The nurse finds there is no available bag to administer. It is most important for the nurse to a) Request a new bag from the pharmacy department. b) Flush the line with 10 mL of sterile saline. c) Infuse a solution containing 10% dextrose and water. d) Catch up with the next bag when it arrives.
answer
C) Infuse a solution containing 10% dextrose and water If the parenteral nutrition solution runs out, a solution of 10% dextrose and water is infused to prevent hypoglycemia. The nurse would then order the next parenteral nutrition bag from the pharmacy. Flushing a peripherally inserted catheter is usually prescribed every 8 hours or per hospital established protocols. It is not the most important activity at this moment. The infusion rate should not be increased to compensate for fluids that were not infused, because hyperglycemia and hyperosmolar diuresis could occur.
question
Patients diagnosed with esophageal varices are at risk for hemorrhagic shock. Which of the following is a sign of potential hypovolemia? a) Hypotension b) Bradycardia c) Polyuria d) Warm moist skin
answer
A) Hypotension Signs of potential hypovolemia include cool, clammy skin, tachycardia, decreased blood pressure, and decreased urine output.
question
Which of the following is caused by improper catheter placement and inadvertent puncture of the pleura? a) Pneumothorax b) Sepsis c) Fluid overload d) Air embolism
answer
A) Pneumothorax A pneumothorax is caused by improper catheter placement and inadvertent puncture of the pleura. Air embolism can occur from a missing cap on a port. Sepsis can be caused by the separation of dressings. Fluid overload is caused by fluids infusing too rapidly.
question
The nurse inserts a nasoduodenal tube for feeding of the client. To check best for placement, the nurse a) Verifies location with an abdominal x-ray b) Aspirates contents and checks the color of the aspirate c) Auscultates when injecting air d) Adds 8 to 10 inches of the tube after inserting to the xiphoid process
answer
A) Verifies location with an abdominal x-ray Initially, an x-ray should be used to confirm placement of the nasoduodenal tube. It is the most accurate method to verify tube placement. Adding 8 to 10 inches to the length of the tube after measuring from nose to earlobe to xiphoid process is not supported, because it does not indicate that the tube will be in the correct position. Intestinal aspirate is usually clear and yellow to bile-colored. Gastric aspirate is usually cloudy and green, tan, off-white, or brown. Food particles may be present. The traditional method of injecting air through the tube while auscultating the epigastric area with a stethoscope to detect air insufflation is also an unreliable indicator.
question
A nurse is reviewing laboratory test results from a client. The report indicates that the client has jaundice. What serum bilirubin level must the client's finding exceed? Enter the correct number only.
answer
Jaundice becomes clinically evident when the serum bilirubin level exceeds 2.5 mg/dL (43 fmol/L).
question
A client with severe and chronic liver disease is showing manifestations related to inadequate vitamin intake and metabolism. He reports difficulty driving at night because he cannot see well. Which of the following vitamins is most likely deficient for this client? a) Vitamin K b) Vitamin A c) Riboflavin d) Thiamine
answer
B) Vitamin A Problems common to clients with severe chronic liver dysfunction result from inadequate intake of sufficient vitamins. Vitamin A deficiency results in night blindness and eye and skin changes. Thiamine deficiency can lead to beriberi, polyneuritis, and Wernicke-Korsakoff psychosis. Riboflavin deficiency results in characteristic skin and mucous membrane lesions. Vitamin K deficiency can cause hypoprothrombinemia, characterized by spontaneous bleeding and ecchymoses.
question
A client diagnosed with acute pancreatitis is being transferred to another facility. The nurse caring for the client completes the transfer summary, which includes information about the client's drinking history and other assessment findings. Which assessment findings confirm his diagnosis? a) Recent weight loss and temperature elevation b) Presence of easy bruising and bradycardia c) Adventitious breath sounds and hypertension d) Presence of blood in the client's stool and recent hypertension
answer
Recent weight loss and temperature elevation Assessment findings associated with pancreatitis include recent weight loss and temperature elevation. Inflammation of the pancreas causes a response that elevates temperature and leads to abdominal pain that typically occurs with eating. Nausea and vomiting may occur as a result of pancreatic tissue damage that's caused by the activation of pancreatic enzymes. The client may experience weight loss because of the lost desire to eat. Blood in stools and recent hypertension aren't associated with pancreatitis; fatty diarrhea and hypotension are usually present. Presence of easy bruising and bradycardia aren't found with pancreatitis; the client typically experiences tachycardia, not bradycardia. Adventitious breath sounds and hypertension aren't associated with pancreatitis.
question
A client with acute liver failure exhibits confusion, a declining level of consciousness, and slowed respirations. The nurse finds him very difficult to arouse. The diagnostic information which best explains the client's behavior is: a) elevated blood urea nitrogen and creatinine levels and hyperglycemia. b) subnormal serum glucose and elevated serum ammonia levels. c) subnormal clotting factors and platelet count. d) elevated liver enzymes and low serum protein level.
answer
B) Subnormal serum glucose and elevated serum ammonia levels In acute liver failure, serum ammonia levels increase because the liver can't adequately detoxify the ammonia produced in the GI tract. In addition, serum glucose levels decline because the liver isn't capable of releasing stored glucose. Elevated serum ammonia and subnormal serum glucose levels depress the level of a client's consciousness. Elevated liver enzymes, low serum protein level, subnormal clotting factors and platelet count, elevated blood urea nitrogen and creatine levels, and hyperglycemia aren't as directly related to the client's level of consciousness.
question
A nurse is caring for a client with cirrhosis. The nurse assesses the client at noon and discovers that the client is difficult to arouse and has an elevated serum ammonia level. The nurse should suspect which situation? a) The client didn't take his morning dose of lactulose (Cephulac). b) The client is relaxed and not in pain. c) The client's hepatic function is decreasing. d) The client is avoiding the nurse.
answer
C) The client's hepatic function is decreasing The decreased level of consciousness caused by an increased serum ammonia level indicates hepatic disfunction. If the client didn't take his morning dose of lactulose, he wouldn't have elevated ammonia levels and decreased level of consciousness this soon. These assessment findings don't indicate that the client is relaxed or avoiding the nurse.
question
A client is admitted for suspected GI disease. Assessment data reveal muscle wasting, a decrease in chest and axillary hair, and increased bleeding tendency. The nurse suspects the client has: a) cirrhosis. b) cholelithiasis. c) appendicitis. d) peptic ulcer disease.
answer
A) Cirrhosis Muscle wasting, a decrease in chest and axillary hair, and increased bleeding tendencies are all symptoms of cirrhosis. The client may also have mild fever, edema, abdominal pain, and an enlarged liver. Clients with peptic ulcer disease complain of a dull, gnawing epigastric pain that's relieved by eating. Appendicitis is characterized by a periumbilical pain that moves to the right lower quadrant and rebound tenderness. Cholelithiasis is characterized by severe abdominal pain that presents several hours after a large meal.
question
The nurse is caring for a client with cirrhosis. Which assessment findings indicate that the client has deficient vitamin K absorption caused by this hepatic disease? a) Ascites and orthopnea b) Gynecomastia and testicular atrophy c) Purpura and petechiae d) Dyspnea and fatigue
answer
C) Purpura and petechiae A hepatic disorder, such as cirrhosis, may disrupt the liver's normal use of vitamin K to produce prothrombin (a clotting factor). Consequently, the nurse should monitor the client for signs of bleeding, including purpura and petechiae. Dyspnea and fatigue suggest anemia. Ascites and orthopnea are unrelated to vitamin K absorption. Gynecomastia and testicular atrophy result from decreased estrogen metabolism by the diseased liver.
question
A nurse is providing dietary instructions to a client with a history of pancreatitis. Which instruction is correct? a) "Maintain a high-sodium, high-calorie diet." b) "Maintain a high-carbohydrate, low-fat diet." c) "Maintain a high-fat, high-carbohydrate diet." d) "Maintain a high-fat diet and drink at least 3 L of fluid a day."
answer
B) Maintain a high carbohydrate, low fat diet A client with a history of pancreatitis should avoid foods and beverages that stimulate the pancreas, such as fatty foods, caffeine, and gas-forming foods; should avoid eating large meals; and should eat plenty of carbohydrates, which are easily metabolized. Therefore, the only correct instruction is to maintain a high-carbohydrate, low-fat diet. An increased sodium or fluid intake isn't necessary because chronic pancreatitis isn't associated with hyponatremia or fluid loss.
question
A client is evaluated for severe pain in the right upper abdominal quadrant, which is accompanied by nausea and vomiting. The physician diagnoses acute cholecystitis and cholelithiasis. For this client, which nursing diagnosis takes top priority? a) Anxiety related to unknown outcome of hospitalization b) Acute pain related to biliary spasms c) Imbalanced nutrition: Less than body requirements related to biliary inflammation d) Deficient knowledge related to prevention of disease recurrence
answer
B) Acute pain related to biliary spams The chief symptom of cholecystitis is abdominal pain or biliary colic. Typically, the pain is so severe that the client is restless and changes positions frequently to find relief. Therefore, the nursing diagnosis of Acute pain related to biliary spasms takes highest priority. Until the acute pain is relieved, the client can't learn about prevention, may continue to experience anxiety, and can't address nutritional concerns.
question
Patients with chronic liver dysfunction have problems with insufficient vitamin intake. Which of the following may occur as a result of vitamin C deficiency? a) Hypoprothrombinemia b) Scurvy c) Beriberi d) Night blindness
answer
B) Scurvy Scurvy may result from a vitamin C deficiency. Night blindness, hypoprothrombinemia, and beriberi do not result from a vitamin C deficiency.
question
Patients diagnosed with esophageal varices are at risk for hemorrhagic shock. Which of the following is a sign of potential hypovolemia? a) Bradycardia b) Hypotension c) Polyuria d) Warm moist skin
answer
B) Hypotension Signs of potential hypovolemia include cool, clammy skin, tachycardia, decreased blood pressure, and decreased urine output.
question
A client being treated for pancreatitis faces the risk of atelectasis. Which of the following interventions would be important to implement to minimize this risk? a) Withhold oral feedings for the client. b) Instruct the client to avoid coughing. c) Monitor pulse oximetry every hour. d) Reposition the client every 2 hours.
answer
D) Reposition the client every 2 hours Repositioning the client every 2 hours minimizes the risk of atelectasis in a client who is being treated for pancreatitis. The client should be instructed to cough every 2 hours to reduce atelectasis. Monitoring the pulse oximetry helps show changes in respiratory status and promote early intervention, but it would do little to minimize the risk of atelectasis. Withholding oral feedings limits the reflux of bile and duodenal contents into the pancreatic duct.
question
A client with hepatitis who has not responded to medical treatment is scheduled for a liver transplant. Which of the following most likely would be ordered? a) Chenodiol b) Ursodiol c) Tacrolimus d) Interferon alfa-2b, recombinant
answer
C) Tacrolimus In preparation for a liver transplant, a client receives immunosuppressants to reduce the risk for organ rejection. Tacrolimus or cyclosporine are two immunosuppresants that may be used. Chenodiol and ursodiol are agents used to dissolve gall stones. Recombinant interferon alfa-2b is used to treat chronic hepatitis B, C, and D to force the virus into remission.
question
A client with liver and renal failure has severe ascites. On initial shift rounds, his primary nurse finds his indwelling urinary catheter collection bag too full to store more urine. The nurse empties more than 2,000 ml from the collection bag. One hour later, she finds the collection bag full again. The nurse notifies the physician, who suspects that a bladder rupture is allowing the drainage of peritoneal fluid. The physician orders a urinalysis to be obtained immediately. The presence of which substance is considered abnormal? a) Albumin b) Chloride c) Urobilinogen d) Creatinine
answer
A) Albumin Albumin is an abnormal finding in a routine urine specimen. Ascites present in liver failure contain albumin; therefore, if the bladder ruptured, ascites containing albumin would drain from the indwelling urinary catheter because the catheter is no longer contained in the bladder. Creatinine, urobilinogen, and chloride are normally found in urine.
question
A physician orders spironolactone (Aldactone), 50 mg by mouth four times daily, for a client with fluid retention caused by cirrhosis. Which finding indicates that the drug is producing a therapeutic effect? a) Loss of 2.2 lb (1 kg) in 24 hours b) Serum potassium level of 3.5 mEq/L c) Blood pH of 7.25 d) Serum sodium level of 135 mEq/L
answer
A) Loss of 2.2 lb (1 kg) in 24 hours Daily weight measurement is the most accurate indicator of fluid status; a loss of 2.2 lb (1 kg) indicates loss of 1 L of fluid. Because spironolactone is a diuretic, weight loss is the best indicator of its effectiveness. This client's serum potassium and sodium levels are normal. A blood pH of 7.25 indicates acidosis, an adverse reaction to spironolactone.
question
When reviewing the history of a client with pancreatic cancer, the nurse would identify which of the following as a possible risk factor? a) Ingestion of caffeinated coffee b) Ingestion of a low-fat diet c) History of pancreatitis d) One-time exposure to petrochemicals
answer
C) History of pancreatitis Pancreatitis is associated with the development of pancreatic cancer. Other factors that correlate with pancreatic cancer include diabetes mellitus, a high-fat diet, and chronic exposure to carcinogenic substances (i.e., petrochemicals). Although data are inconclusive, a relationship may exist between cigarette smoking and high coffee consumption (especially decaffeinated coffee) and the development of pancreatic carcinoma.
question
The nurse is preparing to interview a client with cirrhosis. Based on an understanding of this disorder, which question would be most important to include? a) "What type of over-the-counter pain reliever do you use?" b) "How often do you drink alcohol?" c) "Have you had an infection recently?" d) "Does your work expose you to chemicals?"
answer
B) How often do you drink alcohol? The most common type of cirrhosis results from chronic alcohol intake and is frequently associated with poor nutrition. Although it can follow chronic poisoning with chemicals or ingestion of hepatotoxic drugs such as acetaminophen, asking about alcohol intake would be most important. Asking about an infection or exposure to hepatotoxins or industrial chemicals would be important if the client had postnecrotic cirrhosis.
question
A nurse is preparing a client for surgery. During preoperative teaching, the client asks where is bile stored. The nurse knows that bile is stored in the: a) Cystic duct b) Duodenum c) Gallbladder d) Common bile duct
answer
C) Gallbladder The gallbladder functions as a storage depot for bile.
question
Which of the following symptoms characterizes regional enteritis? a) Severe diarrhea b) Diffuse involvement c) Exacerbations and remissions d) Transmural thickening
answer
D) Transmural thickening Transmural thickening is an early pathologic change of Crohn's disease. Later pathology results in deep, penetrating granulomas. Regional enteritis is characterized by regional discontinuous lesions. Severe diarrhea is characteristic of ulcerative colitis while diarrhea in regional enteritis is less severe. Regional enteritis is characterized by a prolonged and variable course while ulcerative colitis is characterized by exacerbations and remissions.
question
If a client has abdominal surgery and a portion of the small intestine is removed, the client is at risk for which of the following? a) Gastric ulcers b) Malabsorption syndrome c) Constipation d) Cirrhosis
answer
B) Malabsorption syndrome Absorption is the primary function of the small intestine. Vitamins and minerals are absorbed essentially unchanged. Nutrients are absorbed at specific locations in the small intestine.
question
A client with a history of alcohol abuse comes to the emergency department and complains of abdominal pain. Laboratory studies help confirm a diagnosis of acute pancreatitis. The client's vital signs are stable, but the client's pain is worsening and radiating to his back. Which intervention takes priority for this client? a) Providing mouth care b) Administering morphine I.V. as ordered c) Placing the client in a semi-Fowler's position d) Maintaining nothing-by-mouth (NPO) status
answer
B) Administering morphine IV as ordered The nurse should address the client's pain issues first by administering morphine I.V. as ordered. Placing the client in a Semi-Fowler's position, maintaining NPO status, and providing mouth care don't take priority over addressing the client's pain issues.
question
Which of the following is an outcome of histamine 2 (H2)-receptor antagonists blocking the action of histamine in the stomach? a) Blood phosphate levels are elevated. b) Symptoms of gastroesophageal reflux are relieved. c) Acid indigestion is relieved. d) Acid secretion is reduced.
answer
D) Acid secretion is reduced H2-receptor antagonists decrease the amount of hydrochloric acid that the stomach produces by blocking the action of histamine on histamine receptors of potential cells in the stomach.
question
A nonresponsive client has a nasogastric tube to low intermittent suction due to gastrointestinal bleeding. It is most important for the nurse to a) Change the nasal tape every 2 to 3 days. b) Auscultate lung sounds every 4 hours. c) Inspect the nose daily for skin irritation. d) Apply water-based lubricant to the nares daily.
answer
B) Auscultate lung sounds every 4 hours Pulmonary complications may occur as a result of nasogastric intubation. It is a high priority according to Maslow's hierarchy of needs and takes a higher priority over assessing the nose, changing nasal tape, or applying a water-based lubricant.
question
When caring for a client with acute pancreatitis, the nurse should use which comfort measure? a) Encouraging frequent visits from family and friends b) Administering frequent oral feedings c) Positioning the client on the side with the knees flexed d) Administering an analgesic once per shift, as ordered, to prevent drug addiction
answer
C) Postitioning the client on the side with the knees flexed The nurse should place the client with acute pancreatitis in a side-lying position with knees flexed; this position promotes comfort by decreasing pressure on the abdominal muscles. The nurse should administer an analgesic, as needed and ordered, before pain becomes severe, rather than once each shift. Because the client needs a quiet, restful environment during the acute disease stage, the nurse should discourage frequent visits from family and friends. Frequent oral feedings are contraindicated during the acute stage to allow the pancreas to rest.
question
Which of the following medications would the nurse expect the physician to order for a client with cirrhosis who develops portal hypertension? a) Kanamycin (Kantrex) b) Spironolactone (Aldactone) c) Cyclosporine (Sandimmune) d) Lactulose (Cephulac)
answer
B) Spironlactone (Aldactone) For portal hypertension, a diuretic usually an aldosterone antagonist such as spironolactone (Aldactone) is ordered. Kanamycin (Kantrex) would be used to treat hepatic encephalopathy to destroy intestinal microorganisms and decrease ammonia production. Lactulose would be used to reduce serum ammonia concentration in a client with hepatic encephalopathy. Cyclosporine (Sandimmune) would be used to prevent graft rejection after a transplant.
question
A client is prescribed tetracycline to treat peptic ulcer disease. Which of the following instructions would the nurse give the client? a) "Take the medication with milk." b) "Do not drive when taking this medication." c) "Be sure to wear sunscreen while taking this medicine." d) "Expect a metallic taste when taking this medicine, which is normal."
answer
C) Be sure to wear sunscreen while taking this medicine Tetracycline may cause a photosensitivity reaction in clients. The nurse should caution the client to use sunscreen when taking this drug. Dairy products can reduce the effectiveness of tetracycline, so the nurse should not advise him or her to take the medication with milk. A metallic taste accompanies administration of metronidazole (Flagyl). Administration of tetracycline does not necessitate driving restrictions.
question
The nurse observes dry mucous membranes in a client who is receiving tube feedings after an oral surgery. The client also complains of unpleasant tastes and odors. Which of the following measures should be included in the client's plan of care? a) Ensure adequate hydration with additional water. b) Keep the feeding formula refrigerated. c) Provide frequent mouth care. d) Flush the tube with water before adding the feedings.
answer
C) Provide frequent mouth care Frequent mouth care helps to relieve the discomfort from dryness and unpleasant odors and tastes. It can be done with the help of ice chips and analgesic throat lozenges, gargles, or sprays. Adequate hydration is essential. If urine output is less than less than 500 mL/day, formula and additional water can be given as ordered. Keeping the feeding formula refrigerated and unopened until it is ready for use and flushing the tube with water before adding feedings are measures to protect the client from infections.
question
The nurse is caring for a man who has experienced a spinal cord injury. Throughout his recovery, the client expects to gain control of his bowels. The nurse's best response to this client would be which of the following? a) "Over time, the nerve fibers will regrow new tracts, and you can have bowel movements again." b) "Wearing an undergarment will become more comfortable over time." c) "Having a bowel movement is a spinal reflex requiring intact nerve fibers. Yours are not intact." d) "It is not going to happen. Your nerve cells are too damaged."
answer
C) Having a bowel movement is a spinal reflex requiring intact nerve fibers. Yours are not intact The act of defecation is a spinal reflex involving the parasympathetic nerve fibers. Normally, the external anal sphincter is maintained in a state of tonic contraction. With a spinal cord injury, the client no longer has this nervous system control and is often incontinent.
question
After teaching a group of students about the various organs of the upper gastrointestinal tract and possible disorders, the instructor determines that the teaching was successful when the students identify which of the following structures as possibly being affected? a) Large intestine b) Ileum c) Liver d) Stomach
answer
D) Stomach The upper gastrointestinal (GI) tract begins at the mouth and ends at the jejunum. Therefore, the stomach would be a component of the upper GI tract. The lower GI tract begins at the ileum and ends at the anus. The liver is considered an accessory structure.
question
An elderly client asks the nurse how to treat chronic constipation. What is the best recommendation the nurse can make? a) Take a mild laxative such as magnesium citrate when necessary. b) Administer a tap-water enema weekly. c) Administer a phospho-soda (Fleet) enema when necessary. d) Take a stool softener such as docusate sodium (Colace) daily.
answer
D) Take a stool softener such as docuaste sodium (Colace) daily. Stool softeners taken daily promote absorption of liquid into the stool, creating a softer mass. They may be taken on a daily basis without developing a dependence. Dependence is an adverse effect of daily laxative use. Enemas used daily or on a frequent basis can also lead to dependence of the bowel on an external source of stimulation.
question
Following administration of a dose of metoclopramide (Reglan) to the patient, the nurse determines that the medication has been effective when which of the following is noted? A) Decreased blood pressure B) Absence of muscle tremors C) Relief of nausea and vomiting D) No further episodes of diarrhea
answer
C) Relief of nausea and vomiting Metoclopramide is classified as a prokinetic and antiemetic medication. If it is effective, the patient's nausea and vomiting should resolve.
question
The patient receiving chemotherapy rings the call bell and reports an onset of nausea. The nurse should prepare a prn dose of which of the following medications? A) Morphine sulfate B) Zolpidem (Ambien) C) Ondansetron (Zofran) D) Dexamethasone (Decadron)
answer
C) Ondansetron (Zofran) Ondansetron is a 5-HT3 receptor antagonist antiemetic that is especially effective in reducing cancer chemotherapy-induced nausea and vomiting.
question
The patient who is admitted with a diagnosis of diverticulitis and a history of irritable bowel disease and gastroesophageal reflux disease (GERD) has received a dose of Mylanta 30 ml PO. The nurse would evaluate its effectiveness by questioning the patient as to whether which of the following symptoms has been resolved? A) Diarrhea B) Heartburn C) Constipation D) Lower abdominal pain
answer
B) Heartburn Mylanta is an antacid that contains both aluminum and magnesium. It is indicated for the relief of GI discomfort, such as with heartburn associated with GERD.
question
After administering a dose of promethazine (Phenergan) to a patient with nausea and vomiting, the nurse explains that which of the following may be experienced as a common temporary adverse effect of the medication? A) Drowsiness B) Reduced hearing C) Sensation of falling D) Photosensitivity
answer
A) Drowsiness Although being given to this patient as an antiemetic, promethazine also has sedative and amnesic properties. For this reason, the patient is likely to experience drowsiness as an adverse effect of the medication.
question
The nurse is caring for a patient treated with intravenous fluid therapy for severe vomiting. As the patient recovers and begins to tolerate oral intake, the nurse understands that which of the following food choices would be most appropriate? A) Ice tea B) Dry toast C) Warm broth D) Plain hamburger
answer
B) Dry toast Dry toast or crackers may alleviate the feeling of nausea and prevent further vomiting. Extremely hot or cold liquids and fatty foods are generally not well tolerated.
question
The nurse determines that a patient has experienced the beneficial effects of medication therapy with famotidine (Pepcid) when which of the following symptoms is relieved? A) Nausea B) Belching C) Epigastric pain D) Difficulty swallowing
answer
C) Epigastric Pain Famotidine is an H2-receptor antagonist that inhibits parietal cell output of HCl acid and minimizes damage to gastric mucosa related to hyperacidity, thus relieving epigastric pain.
question
A patient reports having dry mouth and asks for some liquid to drink. The nurse reasons that this symptom can most likely be attributed to a common adverse effect of which of the following medications? A) Digoxin (Lanoxin) B) Cefotetan (Cefotan) C) Famotidine (Pepcid) D) Promethazine (Phenergan)
answer
D) Promethazine (Phenergan) A common adverse effect of promethazine, an antihistamine antiemetic agent, is dry mouth; another is blurred vision.
question
A patient with a history of peptic ulcer disease has presented to the emergency department with complaints of severe abdominal pain and a rigid, boardlike abdomen, prompting the health care team to suspect a perforated ulcer. Which of the following actions should the nurse anticipate? A) Providing IV fluids and inserting a nasogastric tube B) Administering oral bicarbonate and testing the patient's gastric pH level C) Performing a fecal occult blood test and administering IV calcium gluconate D) Starting parenteral nutrition and placing the patient in a high-Fowler's position
answer
A) Providing IV fluids and inserting a NG tube A perforated peptic ulcer requires IV replacement of fluid losses and continued gastric aspiration by NG tube. Nothing is given by mouth and gastric pH testing is not a priority. Calcium gluconate is not a medication directly relevant to the patient's suspected diagnosis and parenteral nutrition is not a priority in the short term.
question
The results of a patient's recent endoscopy indicate the presence of peptic ulcer disease (PUD). Which of the following teaching points should the nurse provide to the patient in light of his new diagnosis? A) "You'll need to drink at least two to three glasses of milk daily." B) "It would likely be beneficial for you to eliminate drinking alcohol." C) "Many people find that a minced or pureed diet eases their symptoms of PUD." D) "Your medications should allow you to maintain your present diet while minimizing symptoms."
answer
B) "It would likely be beneficial for you to eliminate drinking alcohol" Although there is no specific recommended dietary modification for PUD, most patients find it necessary to make some sort of dietary modifications to minimize symptoms. Milk may exacerbate PUD and alcohol is best avoided because it can delay healing.
question
The nurse is conducting discharge teaching for a patient with metastatic lung cancer who was admitted with a bowel impaction. Which of the following instructions would be most helpful to prevent further episodes of constipation? A) Maintain a high intake of fluid and fiber in the diet. B) Reduce intake of medications causing constipation. C) Eat several small meals per day to maintain bowel motility. D) Sit upright during meals to increase bowel motility by gravity.
answer
A) Maintain a high intake of fluid and fiber int he diet Increased fluid intake and a high-fiber diet reduce the incidence of constipation caused by immobility, medications, and other factors. Fluid and fiber provide bulk that in turn increases peristalsis and bowel motility.
question
The nurse should administer a prn dose of magnesium hydroxide (MOM) after noting which of the following while reviewing a patient's medical record? A) Abdominal pain and bloating B) No bowel movement for 3 days C) A decrease in appetite by 50% over 24 hours D) Muscle tremors and other signs of hypomagnesemia
answer
B) No bowel movement for 3 days MOM is an osmotic laxative that produces a soft, semisolid stool usually within 15 minutes to 3 hours. This medication would benefit the patient who has not had a bowel movement for 3 days.
question
The nurse is preparing to administer a dose of bisacodyl (Dulcolax). In explaining the medication to the patient, the nurse would state that it acts in which of the following ways? A) Increases bulk in the stool B) Lubricates the intestinal tract to soften feces C) Increases fluid retention in the intestinal tract D) Increases peristalsis by stimulating nerves in the colon wall
answer
D) Increases peristalsis by stimulating nerves in the colon wall Bisacodyl is a stimulant laxative that aids in producing a bowel movement by irritating the colon wall and stimulating enteric nerves. It is available in oral and suppository forms.
question
The nurse is preparing to administer a scheduled dose of docusate sodium (Colace) when the patient complains of an episode of loose stool and does not want to take the medication. Which of the following is the appropriate action by the nurse? A) Write an incident report about this untoward event. B) Attempt to have the family convince the patient to take the ordered dose. C) Withhold the medication at this time and try to administer it later in the day. D) Chart the dose as not given on the medical record and explain in the nursing progress notes.
answer
D) Chart the dose as not given on the medical record and explain in the nursing progress notes. Whenever a patient refuses medication, the dose should be charted as not given. An explanation of the reason should then be documented in the nursing progress notes. In this instance, the refusal indicates good judgment by the patient.
question
A patient is scheduled to receive "Colace 100 mg PO." The patient asks to take the medication in liquid form, and the nurse obtains an order for the interchange. Available is a syrup that contains 150 mg/15 ml. How many milliliters does the nurse administer? A) 3 B) 5 C) 10 D) 12
answer
C) 10 mL The concentration of the syrup is 10 mg/ml. Therefore, a 100-mg dose necessitates 10 ml.
question
The nurse would instruct the patient to do which of the following to best enhance the effectiveness of a daily dose of docusate sodium (Colace)? A) Take a dose of mineral oil at the same time. B) Add extra salt to food on at least one meal tray. C) Ensure dietary intake of 10 g of fiber each day. D) Take each dose with a full glass of water or other liquid.
answer
D) Take each dose with a full glass of water or other liquid Docusate lowers the surface tension of stool, permitting water and fats to penetrate and soften the stool for easier passage. The patient should take the dose with a full glass of water and should increase overall fluid intake, if able, to enhance effectiveness of the medication. Dietary fiber intake should be a minimum of 20 g daily to prevent constipation.
question
The nurse would question the use of which of the following cathartic agents in a patient with renal insufficiency? A) Bisacodyl B) Lubiprostone C) Cascara sagrada D) Milk of magnesia
answer
D) Milk of Magnesia Milk of magnesia may cause hypermagnesemia in patients with renal insufficiency. The nurse should question this order with the health care provider before administration.
question
A patient who is administering a bisacodyl (Dulcolax) suppository asks the nurse how long it will take to work. The nurse replies that the patient will probably need to use the bedpan or commode within which of the following time frames after administration? A) 2-5 Minutes B) 15-60 Minutes C) 2-4 Hours D) 6-8 Hours
answer
B) 15-60 minutes Bisacodyl suppositories usually are effective within 15 to 60 minutes of administration, so the nurse should plan accordingly to assist the patient to use the bedpan or commode.
question
The nurse is caring for a patient in the emergency department with complaints of acute abdominal pain, nausea, and vomiting. When the nurse palpates the patient's left lower abdominal quadrant, the patient complains of pain in the right lower quadrant. The nurse will document this as which of the following diagnostic signs of appendicitis? A) Rovsing sign B) Referred pain C) Chvostek's sign D) Rebound tenderness
answer
A) Rovsing sign In patients with suspected appendicitis, Rovsing sign may be elicited by palpation of the left lower quadrant, causing pain to be felt in the right lower quadrant.
question
The nurse is caring for a 68-year-old patient admitted with abdominal pain, nausea, and vomiting. The patient has an abdominal mass and a bowel obstruction is suspected. The nurse auscultating the abdomen listens for which of the following types of bowel sounds that is consistent with the patient's clinical picture? A) Low pitched and rumbling above the area of obstruction B) High pitched and hypoactive below the area of obstruction C) Low pitched and hyperactive below the area of obstruction D) High pitched and hyperactive above the area of obstruction
answer
A) Low pitched and rumbling above the area of obstruction Early in intestinal obstruction, the patient's bowel sounds are hyperactive and high pitched, sometimes referred to as "tinkling" above the level of the obstruction. This occurs because peristaltic action increases to "push past" the area of obstruction. As the obstruction becomes complete, bowel sounds decrease and finally become absent.
question
The nurse is planning care for a 68-year-old patient with an abdominal mass and suspected bowel obstruction. Which of the following factors in the patient's history increases the patient's risk for colorectal cancer? A) Osteoarthritis B) History of rectal polyps C) History of lactose intolerance D) Use of herbs as dietary supplements
answer
B) History of rectal polyps A history of rectal polyps places this patient at risk for colorectal cancer. This tissue can degenerate over time and become malignant. The other factors identified do not pose additional risk to the patient.
question
The nurse is preparing to insert a nasogastric tube into a 68-year-old patient with an abdominal mass and suspected bowel obstruction. The patient asks the nurse why this procedure is necessary. Which of the following responses is most appropriate? A) "The tube will help to drain the stomach contents and prevent further vomiting." B) "The tube will push past the area that is blocked, and thus help to stop the vomiting." C) "The tube is just a standard procedure before many types of surgery to the abdomen." D) "The tube will let us measure your stomach contents, so that we can plan what type of IV fluid replacement would be best."
answer
A) The tube will help drain the stomach contents and prevent further vomiting The nasogastric tube is used to decompress the stomach by draining stomach contents, and thereby prevent further vomiting.
question
A 61-year-old patient with suspected bowel obstruction has had a nasogastric tube inserted at 4:00 am. The nurse shares in the morning report that the day shift staff should check the tube for patency at which of the following times? A) 7:00 am, 10:00 am, and 1:00 pm B) 8:00 am and 12:00 pm C) 9:00 am and 3:00 pm D) 9:00 am, 12:00 pm, and 3:00 pm
answer
B) 8:00 am and 12:00 pm A nasogastric tube should be checked for patency routinely at 4-hour intervals. Thus if the tube were inserted at 4:00 am, it would be due to be checked at 8:00 am and 12:00 pm.
question
The nurse who inserted a nasogastric tube for a 68-year-old patient with suspected bowel obstruction should write which of the following priority nursing diagnoses on the patient's problem list? A) Anxiety related to nasogastric tube placement B) Abdominal pain related to nasogastric tube placement C) Risk for deficient knowledge related to nasogastric tube placement D) Altered oral mucous membrane related to nasogastric tube placement
answer
D) Altered oral mucous membrane related to nasogastric tube placement With nasogastric tube placement, the patient is likely to breathe through the mouth and may experience irritation in the affected nares. For this reason, the nurse should plan preventive measures based on this nursing diagnosis.
question
A colectomy is scheduled for a 68-year-old woman with an abdominal mass, possible bowel obstruction, and a history of rectal polyps. The nurse should plan to include which of the following prescribed measures in the preoperative preparation of this patient? A) Instruction on irrigating a colostomy B) Administration of a cleansing enema C) A high-fiber diet the day before surgery D) Administration of IV antibiotics for bowel preparation
answer
B) Administration of a cleansing enema Preoperative preparation for bowel surgery typically includes bowel cleansing with antibiotics, such as oral neomycin and cleansing enemas, including Fleet enemas.
question
Which of the following would be the highest priority information to include in preoperative teaching for a 68-year-old patient scheduled for a colectomy? A) How to care for the wound B) How to deep breathe and cough C) The location and care of drains after surgery D) What medications will be used during surgery
answer
B) How to deep breathe and cough Because anesthesia, an abdominal incision, and pain can impair the patient's respiratory status in the postoperative period, it is of high priority to teach the patient to cough and deep breathe. Otherwise, the patient could develop atelectasis and pneumonia, which would delay early recovery from surgery and hospital discharge.
question
The nurse asks a 68-year-old patient scheduled for colectomy to sign the operative permit as directed in the physician's preoperative orders. The patient states that the physician has not really explained well what is involved in the surgical procedure. Which of the following is the most appropriate action by the nurse? A) Ask family members whether they have discussed the surgical procedure with the physician. B) Have the patient sign the form and state the physician will visit to explain the procedure before surgery. C) Explain the planned surgical procedure as well as possible, and have the patient sign the consent form. D) Delay the patient's signature on the consent and notify the physician about the conversation with the patient.
answer
D) Delay the patient's signature on the consent and notify the physician about the conversation with the patient. The patient should not be asked to sign a consent form unless the procedure has been explained to the satisfaction of the patient. The nurse should notify the physician, who has the responsibility for obtaining consent.
question
Two days following a colectomy for an abdominal mass, a patient reports gas pains and abdominal distention. The nurse plans care for the patient based on the knowledge that the symptoms occur as a result of which of the following? A) Impaired peristalsis B) Irritation of the bowel C) Nasogastric suctioning D) Anastomosis site inflammation
answer
A) Impaired peristalsis Until peristalsis returns to normal following anesthesia, the patient may experience slowed gastrointestinal motility leading to gas pains and abdominal distention.
question
Following bowel resection, a patient has a nasogastric tube to suction, but complains of nausea and abdominal distention. The nurse irrigates the tube prn as ordered, but the irrigating fluid does not return. Which of the following should be the priority action by the nurse? A) Notify the physician. B) Auscultate for bowel sounds. C) Reposition the tube and check for placement. D) Remove the tube and replace it with a new one.
answer
C) Reposition the tube and check for placement The tube may be resting against the stomach wall. The first action by the nurse, since this intestinal surgery (not gastric surgery), is to reposition the tube and check it again for placement.
question
The nurse is caring for a postoperative patient with a colostomy. The nurse is preparing to administer a dose of famotidine (Pepcid) when the patient asks why the medication was ordered since the patient does not have a history of heartburn or gastroesophageal reflux disease (GERD). Which of the following would be the most appropriate response by the nurse? A) "This will prevent air from accumulating in the stomach, causing gas pains." B) "This will prevent the heartburn that occurs as a side effect of general anesthesia." C) "The stress of surgery is likely to cause stomach bleeding if you do not receive it." D) "This will reduce the amount of HCl in the stomach until the nasogastric tube is removed, and you can eat a regular diet again."
answer
D) This will reduce the amount of HCl in the stomach until the nasogastric tube is removed, and you can eat a regular diet again Famotidine is an H2-receptor antagonist that inhibits gastric HCl secretion and thus minimizes damage to gastric mucosa while the patient is not eating a regular diet after surgery.
question
A 54-year-old patient admitted with diabetes mellitus, malnutrition, osteomyelitis, and alcohol abuse has a serum amylase level of 280 U/L and a serum lipase level of 310 U/L. To which of the following diagnoses does the nurse attribute these findings? A) Malnutrition B) Osteomyelitis C) Alcohol abuse D) Diabetes mellitus
answer
C) Alcohol Abuse The patient with alcohol abuse could develop pancreatitis as a complication, which would increase the serum amylase (normal 30-122 U/L) and serum lipase (normal 31-186 U/L) levels as shown.
question
The health care provider orders lactulose for a patient with hepatic encephalopathy. The nurse will monitor for effectiveness of this medication for this patient by assessing which of the following? A) Relief of constipation B) Relief of abdominal pain C) Decreased liver enzymes D) Decreased ammonia levels
answer
D) Decreased ammonia levels Hepatic encephalopathy is a complication of liver disease and is associated with elevated serum ammonia levels. Lactulose traps ammonia in the intestinal tract. Its laxative effect then expels the ammonia from the colon, resulting in decreased serum ammonia levels and correction of hepatic encephalopathy.
question
The family of a patient newly diagnosed with hepatitis A asks the nurse what they can do to prevent becoming ill themselves. Which of the following responses by the nurse is most appropriate? A) "The hepatitis vaccine will provide immunity from this exposure and future exposures." B) "I am afraid there is nothing you can do since the patient was infectious before admission." C) "You will need to be tested first to make sure you don't have the virus before we can treat you." D) "An injection of immunoglobulin will need to be given to prevent or minimize the effects from this exposure."
answer
D) An injection of immunoglobulin will need to be given to prevent or minimize the effects from this exposure Immunoglobulin provides temporary (1-2 months) passive immunity and is effective for preventing hepatitis A if given within 2 weeks after exposure. It may not prevent infection in all persons, but it will at least modify the illness to a subclinical infection. The hepatitis vaccine is only used for preexposure prophylaxis.
question
When planning care for a patient with cirrhosis, the nurse will give highest priority to which of the following nursing diagnoses? A) Imbalanced nutrition: less than body requirements B) Impaired skin integrity related to edema, ascites, and pruritus C) Excess fluid volume related to portal hypertension and hyperaldosteronism D) Ineffective breathing pattern related to pressure on diaphragm and reduced lung volume
answer
D) Ineffective breathing pattern related to pressure on diaphragm and reduced lung volume Although all of these nursing diagnoses are appropriate and important in the care of a patient with cirrhosis, airway and breathing are always the highest priorities.
question
When caring for a patient with liver disease, the nurse recognizes the need to prevent bleeding resulting from altered clotting factors and rupture of varices. Which of the following nursing interventions would be appropriate to achieve this outcome (select all that apply)? A) Use smallest gauge possible when giving injections or drawing blood. B) Teach patient to avoid straining at stool, vigorous blowing of nose, and coughing. C) Advise patient to use soft-bristle toothbrush and avoid ingestion of irritating food. D) Apply gentle pressure for the shortest possible time period after performing venipuncture. E) Instruct patient to avoid aspirin and NSAIDs to prevent hemorrhage when varices are present.
answer
A,B,C,E Using the smallest gauge for injections will minimize the risk of bleeding into the tissues. Avoiding straining, nose blowing, and coughing will reduce the risk of hemorrhage at these sites. The use of a soft-bristle toothbrush and avoidance of irritating food will reduce injury to highly vascular mucous membranes. The nurse should apply gentle but prolonged pressure to venipuncture sites to minimize the risk of bleeding.
question
A patient with type 2 diabetes and cirrhosis asks the nurse if it would be okay to take silymarin (milk thistle) to help minimize liver damage. The nurse responds based on knowledge that A) Milk thistle may affect liver enzymes and thus alter drug metabolism. B) Milk thistle is generally safe in recommended doses for up to 10 years. C) There is unclear scientific evidence for the use of milk thistle in treating cirrhosis. D) Milk thistle may elevate the serum glucose levels and is thus contraindicated in diabetes.
answer
A) Milk thistle may affect liver enzymes and thus alter drug metabolism There is good scientific evidence for the use of milk thistle as an antioxidant to protect the liver cells from toxic damage in the treatment of cirrhosis. It is noted to be safe for up to 6 years, not 10 years, and it may lower, not elevate, blood glucose levels. It does affect liver enzymes and thus could alter drug metabolism. Therefore patients will need to be monitored for drug interactions.
question
When caring for a patient with a biliary obstruction, the nurse will anticipate administering which of the following vitamin supplements (select all that apply)? A) Vitamin A B) Vitamin D C) Vitamin E D) Vitamin K E) Vitamin B
answer
A,B,C,D Biliary obstruction prevents bile from entering the small intestine and thus prevents the absorption of fat-soluble vitamins. Vitamins A, D, E, and K are all fat soluble and thus would need to be supplemented in a patient with biliary obstruction.
question
Diet therapy for patients diagnosed with IBS include which of the following? a) High-fiber diet b) Fluids with meals c) Caffeinated products d) Spicy foods
answer
A) High fiber diet A high-fiber diet is prescribed to help control diarrhea and constipation. Foods that are possible irritants such as caffeine, spicy foods, lactose, beans, fried foods, corn, wheat, alcohol should be avoided. Fluids should not be taken with meals because this results in abdominal distention.
question
Which of the following is a parasympathetic response in the GI tract? a) Blood vessel constriction b) Decreased gastric secretion c) Decreased motility d) Increased peristalsis
answer
D) Increased peristalsis Increased peristalsis is a parasympathetic response in the GI tract. Decreased gastric secretion, blood vessel constriction, and decreased motility are sympathetic responses in the GI tract.
question
A nurse is assisting with a percutaneous liver biopsy. Place the steps involved in care in the correct sequence from first to last. Ensure that the biopsy equipment is assembled and in order. Help the client assume a supine position. Make sure that the specimen container is labeled and delivered to the laboratory. While the physician inserts the needle, instruct the client to take a deep breath and hold it to keep the liver as near to the abdominal wall as possible. Place a rolled towel beneath the client's right lower ribs.
answer
Ensure that the biopsy equipment is assembled and in order. Help the client assume a supine position. Place a rolled towel beneath the client's right lower ribs. While the physician inserts the needle, instruct the client to take a deep breath and hold it to keep the liver as near to the abdominal wall as possible. Make sure that the specimen container is labeled and delivered to the laboratory. When assisting with a percutaneous liver biopsy, the nurse ensures that the biopsy equipment is assembled and in order. He or she helps the client assume a supine position with a rolled towel beneath the right lower ribs. Before the physician inserts the needle, the nurse instructs the client to take a deep breath and hold it to keep the liver as near to the abdominal wall as possible. After specimen cells are obtained, they are placed in a preservative. The nurse makes sure that the specimen container is labeled and delivered to the laboratory.
question
A client is admitted to the healthcare facility suspected of having acute pancreatitis and undergoes laboratory testing. Which of the following would the nurse expect to find? a) Decreased white blood cell count b) Decreased liver enzyme levels c) Elevated urine amylase levels d) Increased serum calcium levels
answer
C) Elevated urine amylase levels Elevated serum and urine amylase, lipase, and liver enzyme levels accompany significant pancreatitis. If the common bile duct is obstructed, the bilirubin level is above normal. Blood glucose levels and white blood cell counts can be elevated. Serum electrolyte levels (calcium, potassium, and magnesium) are low.
question
The most common symptom of esophageal disease is a) nausea. b) odynophagia. c) vomiting. d) dysphagia.
answer
D) Dysphagia This symptom may vary from an uncomfortable feeling that a bolus of food is caught in the upper esophagus to acute pain on swallowing. Nausea is the most common symptom of gastrointestinal problems in general. Vomiting is a nonspecific symptom that may have a variety of causes. Odynophagia refers specifically to acute pain on swallowing.
question
The client is experiencing swallowing difficulties and is now scheduled to receive a gastric feeding. She has the following oral medications prescribed: furosemide (Lasix), digoxin, enteric coated aspirin (Ecotrin), and vitamin E. The nurse withholds a) furosemide b) digoxin c) vitamin E d) enteric coated aspirin
answer
D) Enteric coated aspirin Simple compressed tablets (furosemide, digoxin) may be crushed and dissolved in water. Soft gelatin capsules filled with liquid (vitamin E) may be opened, and the contents squeezed out. Enteric coated tablets (enteric coated aspirin) are not to be crushed and a change in the form of the medications is required.
question
A physician has ordered a liver biopsy for a client whose condition is deteriorating. Which of the following places the client at high risk due to her altered liver function during the biopsy? a) Low hemoglobin b) Decreased prothrombin time c) Low sodium level d) Low platelet count
answer
D) Low platelet count Certain blood tests provide information about liver function. Prolonged prothrombin time (PT) and low platelet count place the client at high risk for hemorrhage. The client may receive intravenous (IV) administration of vitamin K or infusions of platelets before liver biopsy to reduce the risk of bleeding.
question
A client with liver and renal failure has severe ascites. On initial shift rounds, his primary nurse finds his indwelling urinary catheter collection bag too full to store more urine. The nurse empties more than 2,000 ml from the collection bag. One hour later, she finds the collection bag full again. The nurse notifies the physician, who suspects that a bladder rupture is allowing the drainage of peritoneal fluid. The physician orders a urinalysis to be obtained immediately. The presence of which substance is considered abnormal? a) Albumin b) Chloride c) Creatinine d) Urobilinogen
answer
A) Albumin Albumin is an abnormal finding in a routine urine specimen. Ascites present in liver failure contain albumin; therefore, if the bladder ruptured, ascites containing albumin would drain from the indwelling urinary catheter because the catheter is no longer contained in the bladder. Creatinine, urobilinogen, and chloride are normally found in urine.
question
An elderly patient diagnosed with diarrhea is taking digoxin (Lanoxin). Which of the following electrolyte imbalances should the nurse be alert to? a) Hyponatremia b) Hypokalemia c) Hypernatremia d) Hyperkalemia
answer
B) Hypokalemia The older person taking digitalis must be aware of how quickly dehydration and hypokalemia can occur with diarrhea. The nurse teaches the patient to recognize the symptoms of hypokalemia because low levels of potassium intensify the action of digitalis, leading to digitalis toxicity.
question
A home care nurse is caring for a client with complaints of epigastric discomfort who is scheduled for a barium swallow. Which statement by the client indicates an understanding of the test? a) "I'll drink full liquids the day before the test." b) "There is no need for special preparation before the test." c) "I'll take a laxative to clear my bowels before the test." d) "I'll avoid eating or drinking anything 6 to 8 hours before the test."
answer
D) I'll avoid eating or drinking anything 6 to 8 hours before the test The client demonstrates understanding of a barium swallow when he states that he must refrain from eating or drinking for 6 to 8 hours before the test. No other preparation is needed. Before a lower GI series, the client should eat a low-residue or clear liquid diet for 2 days and take a potent laxative and an oral liquid preparation.
question
Which of the following surgical procedures for obesity utilizes a prosthetic device to restrict oral intake? a) Vertical-banded gastroplasty b) Roux-en-Y gastric bypass c) Gastric banding d) Biliopancreatic diversion with duodenal switch
answer
C) Gastric banding In gastric banding, a prosthetic device is used to restrict oral intake by creating a small pouch of 10 to 15 milliliters that empties through the narrow outlet into the remainder of the stomach. Roux-en-Y gastric bypass uses a horizontal row of staples across the fundus of the stomach to create a pouch with a capacity of 20 to 30 mL. Vertical-banded gastroplasty involves placement of a vertical row of staples along the lesser curvature of the stomach, creating a new, small gastric pouch. Biliopancreatic diversion with duodenal switch combines gastric restriction with intestinal malabsorption.
question
When assisting with the plan of care for a client receiving tube feedings, which of the following would the nurse include to reduce the client's risk for aspiration? a) Administering 15 to 30 mL of water every 4 hours. b) Aspirating for residual contents every 4 to 8 hours. c) Keeping the client in a semi-Fowler's position at all times. d) Giving the feedings at room temperature.
answer
C) Keeping the client in a semi Fowler's position at all times With continuous tube feedings, the nurse needs to keep the client in a semi-Fowler's position at all times to reduce regurgitation and the risk for aspiration. Aspirating for residual contents helps to ensure adequate nutrition and prevent overfeeding. Administering 15 to 30 mL of water every 4 hours helps to maintain tube patency. Giving the feedings at room temperature reduces the risk for diarrhea.
question
A patient receives atropine, an anticholinergic drug, in preparation for surgery. The nurse expects this drug to affect the GI tract by: a) increasing gastric emptying b) relaxing pyloric and ileocecal sphincters c) decreasing secretions and peristaltic action d) stimulating the nervous system of the GI tract
answer
c) decreasing secretions and peristaltic action The parasympathetic nervous system increasing motility and secretions and relaxing sphincters to promote movement of contents. A drug that blocks this activity decreases secretions and peristalsis, slows gastric emptying, and contracts sphincters. The enteric nervous system of the GI tract is modulated by sympathetic and parasympathetic influence
question
After eating, a patient with an inflamed gallbladder experiences pain caused by contraction of the gallbladdder. The mechanism responsible for this action is a) production of bile by the liver b) production of secretin by the duodenum c) release of gastrin from the stomach antrum d) production of cholecystokinin by the duodenum
answer
d) production of cholecystokinin by the duodenum Cholecystokinin is secreted by the duodenal mucosa when fats and amino acids enter the duodenum and stimulates the gallbladder to release bile and emulsify the fats for digestion. The bile is produced by the liver but stored in the gallbladder. Secretin is responsible for stimulating pancreatic bicarbonate secretion, and gastrin increases gastric motility and acid secretion.
question
When caring for a patient who has had most of the stomach surgically removed, the nurse plans to teach the client a) that extra iron will need to be taken to prevent anemia b) to avoid foods with lactose to prevent diarrhea and bloating c) that lifelong supplementation of cobalamin will be needed d) that, because of the absence of digestive enzymes, protein malnurition is likely
answer
c) that lifelong supplementation of cobalamin will be needed The stomach secretes intrinsic factor necessary for cobalamin absorption in the intestine. In removal of part or all of the stomach, cobalamin must be supplemented for life.
question
True or False? The structure that prevents reflux of stomach contents into the esophagus is the upper esophageal sphincter.
answer
False The structure that prevents reflux of stomach contents into the esophagus is the lower esophageal sphincter.
question
True or False? The nurse encourages that patient with chronic constipation to attempt defecation after the first meal of the day because gastrocolic and duodenocolic reflexes increase colon peristalsis at that time.
answer
True
question
True or False? A drug that clocks the release of secretions from the stomach's chief cells will decrease gastric acidity.
answer
False A drug that clocks the release of secretions from the stomach's parietal cells will decrease gastric acidity.
question
