question
When assessing a patient's abdomen, what would be most appropriate for the nurse to do? 1. Palpate the abdomen before auscultation. 2. Percuss the abdomen before auscultation. 3. Auscultate the abdomen before palpation. 4. Perform deep palpation before light palpation.
answer
3 During examination of the abdomen, auscultation is done before percussion and palpation because these latter procedures may alter the bowel sounds.
question
When preparing a patient for a capsule endoscopy study, what should the nurse do? 1. Ensure the patient understands the required bowel preparation. 2. Have the patient return to the procedure room for removal of the capsule. 3. Teach the patient to maintain a clear liquid diet throughout the procedure. 4. Explain to the patient that conscious sedation will be used during placement of the capsule.
answer
1 A capsule endoscopy study involves the patient performing a bowel prep to cleanse the bowel before swallowing the capsule. The patient will be on a clear liquid diet for 1 to 2 days before the procedure and will remain NPO for 4 to 6 hours after swallowing the capsule. The capsule is disposable and will pass naturally with the bowel movement, although the monitoring device will need to be removed.
question
Inspection of an older patient's mouth reveals the presence of white, curd-like lesions on the patient's tongue. What is the most likely etiology for this abnormal assessment finding? 1. Herpesvirus 2. Candida albicans 3. Vitamin deficiency 4. Irritation from ill-fitting dentures
answer
2 White, curd-like lesions surrounded by erythematous mucosa are associated with oral candidiasis. Herpesvirus causes benign vesicular lesions in the mouth. Vitamin deficiencies may cause a reddened, ulcerated, swollen tongue. Irritation from ill-fitting dentures will cause friable, edematous, painful, bleeding gingivae.
question
The nurse should recognize that the liver performs which functions (select all that apply)? 1. Bile storage 2. Detoxification 3. Protein metabolism 4. Steroid metabolism 5. Red blood cell (RBC) destruction
answer
2, 3, 4 The liver performs multiple major functions that aid in the maintenance of homeostasis. These include metabolism of proteins and steroids as well as detoxification of drugs and metabolic waste products. The Kupffer cells of the liver participate in the breakdown of old RBCs. The liver produces bile, but storage occurs in the gall bladder.
question
The health care team is assessing a male patient for acute pancreatitis after he presented to the emergency department with severe abdominal pain. Which laboratory value is the best diagnostic indicator of acute pancreatitis? 1. Gastric pH 2. Blood glucose 3. Serum amylase 4. Serum potassium
answer
3 Elevated serum amylase levels indicate early pancreatic dysfunction and are used to diagnose acute pancreatitis. Serum lipase levels stay elevated longer than serum amylase in acute pancreatitis. Blood glucose, gastric pH, and potassium levels are not direct indicators of acute pancreatic dysfunction.
question
The nurse is performing a focused abdominal assessment of a patient who has been recently admitted. In order to palpate the patient's liver, where should the nurse palpate the patient's abdomen? 1. Left lower quadrant 2. Left upper quadrant 3. Right lower quadrant 4. Right upper quadrant
answer
4 Although the left lobe of the liver is located in the left upper quadrant of the abdomen, the bulk of the liver is located in the right upper quadrant.
question
The patient had a car accident and was "scared to death." The patient is now reporting constipation. What affecting the gastrointestinal (GI) tract does the nurse know could be contributing to the constipation? 1. The patient is too nervous to eat or drink, so there is no stool. 2. The sympathetic nervous system was activated, so the GI tract was slowed. 3. The parasympathetic nervous system is now functioning to slow the GI tract. 4. The circulation in the GI system has been increased, so less waste is removed.
answer
2 The constipation is most likely related to the sympathetic nervous system activation from the stress related to the accident. SNS activation can decrease peristalsis. Even without oral intake for a short time, stool will be formed. The parasympathetic system stimulates peristalsis. The circulation to the GI system is decreased with stress.
question
A 90-year-old healthy man is suffering from dysphagia. The nurse explains what age-related change of the GI tract is the most likely cause of his difficulty? 1. Xerostomia 2. Esophageal cancer 3. Decreased taste buds 4. Thinner abdominal wall
answer
1 Xerostomia, decreased volume of saliva, leads to dry oral mucosa and dysphagia. Esophageal cancer is not an age-related change. Decreased taste buds and a thinner abdominal wall do not contribute to difficulty swallowing.
question
A patient had a stomach resection for stomach cancer. The nurse should teach the patient about the loss of the hormone that stimulates gastric acid secretion and motility and maintains lower esophageal sphincter tone. Which hormone will be decreased with a gastric resection? 1. Gastrin 2. Secretin 3. Cholecystokinin 4. Gastric inhibitory peptide
answer
1 Gastrin is the hormone activated in the stomach (and duodenal mucosa) by stomach distention that stimulates gastric acid secretion and motility and maintains lower esophageal sphincter tone. Secretin inhibits gastric motility and acid secretion and stimulates pancreatic bicarbonate secretion. Cholecystokinin allows increased flow of bile into the duodenum and release of pancreatic digestive enzymes. Gastric inhibitory peptide inhibits gastric acid secretion and motility.
question
The patient tells the nurse she had a history of abdominal pain, so she had a surgery to make an opening into the common bile duct to remove stones. The nurse knows that this surgery is called a 1. colectomy 2. cholecystectomy 3. choledocholithotomy 4. choledochojejunostomy
answer
3 A choledocholithotomy is an opening into the common bile duct for the removal of stones. A colectomy is the removal of the colon. The cholecystectomy is the removal of the gallbladder. The choledochojejunostomy is an opening between the common bile duct and the jejunum.
question
The ED nurse has inspected, auscultated, and palpated the abdomen with no obvious abnormalities, except pain. When the nurse palpates the abdomen for rebound tenderness, there is severe pain. The nurse should know that this could indicate what problem? 1. Hepatic cirrhosis 2. Hypersplenomegaly 3. Gall bladder distention 4. Peritoneal inflammation
answer
4 When palpating for rebound tenderness, the problem area of the abdomen will produce pain and severe muscle spasm when there is peritoneal inflammation. Hepatic cirrhosis, hypersplenomegaly, and gall bladder distention do not manifest with rebound tenderness.
question
A patient who is scheduled for surgery with general anesthesia in 1 hour is observed with a moist, but empty water glass in his hand. Which assessment finding may indicate that the patient drank a glass of water? 1. Flat abdomen without movement upon inspection 2. Tenderness at left upper quadrant upon palpation 3. Easily heard, loud gurgling in the right upper quadrant 4. High-pitched, hollow sounds in the left upper quadrant
answer
3 If the patient drank water on an empty stomach, gurgling can be assessed without a stethoscope or assessed with auscultation. High-pitched, hollow sounds are tympanic and indicate an empty cavity. A flat abdomen and tenderness do not indicate that the patient drank a glass of water.
question
When caring for the patient with heart failure, the nurse knows that which gastrointestinal process is most dependent on cardiac output and may affect the patient's nutritional status? 1. Ingestion 2. Digestion 3. Absorption 4. Elimination
answer
3 Substances that interface with the absorptive surfaces of the GI tract (primarily in the small intestine) diffuse across the intestinal membranes into intestinal capillaries and are then carried to other parts of the body for use in energy production. The cardiac output provides the blood flow for this absorption of nutrients to occur.
question
An 85-year-old woman seen in the primary care provider's office for a well check complains of difficulty swallowing. What common effect of aging should the nurse assess for as a possible cause? 1. Anosmia 2. Xerostomia 3. Hypochlorhydria 4. Salivary gland tumor
answer
2 Xerostomia (decreased saliva production), or dry mouth, affects many older adults and may be associated with difficulty swallowing (dysphagia). Anosmia is loss of sense of smell. Hypochlorhydria, a decrease in stomach acid, does not affect swallowing. Salivary gland tumors are not common.
question
The nurse is reviewing the home medication list for a 44-year-old man admitted with suspected hepatic failure. Which medication could cause hepatotoxicity? 1. Nitroglycerin 2. Digoxin (Lanoxin) 3. Ciprofloxacin (Cipro) 4. Acetaminophen (Tylenol)
answer
4 Many chemicals and drugs are potentially hepatotoxic (see Table 39-6) and result in significant patient harm unless monitored closely. For example, chronic high doses of acetaminophen and nonsteroidal antiinflammatory drugs (NSAIDs) may be hepatotoxic.
question
The nurse is assessing a 50-year-old woman admitted with a possible bowel obstruction. Which assessment finding would be expected in this patient? 1. Tympany to abdominal percussion 2. Aortic pulsation visible in epigastric region 3. High-pitched sounds on abdominal auscultation 4. Liver border palpable 1 cm below the right costal margin
answer
3 The bowel sounds are more high pitched (rushes and tinkling) when the intestines are under tension, as in intestinal obstruction. Bowel sounds may also be diminished or absent with an intestinal obstruction. Normal findings include aortic pulsations on inspection and tympany with percussion, and the liver may be palpable 1 to 2 cm along the right costal margin.
question
A 62-year-old woman patient is scheduled for a percutaneous transhepatic cholangiography to restore biliary drainage. The nurse discusses the patient's health history and is most concerned if the patient makes which statement? 1. "I am allergic to bee stings." 2. "My tongue swells when I eat shrimp." 3. "I have had epigastric pain for 2 months." 4. "I have a pacemaker because my heart rate was slow."
answer
2 The percutaneous transhepatic cholangiography procedure will include the use of radiopaque contrast medium. Patients allergic to shellfish and iodine are also allergic to contrast medium. Having a pacemaker will not affect the patient during this procedure. It would be expected that the patient would have some epigastric pain given the patient's condition.
question
A 35-year-old man with a family history of adenomatous polyposis had a colonoscopy with removal of multiple polyps. Which signs and symptoms should the nurse teach the patient to report immediately? 1. Fever and abdominal pain 2. Flatulence and liquid stool 3. Loudly audible bowel sounds 4. Sleepiness and abdominal cramps
answer
1 The patient should be taught to observe for signs of rectal bleeding and peritonitis. Fever, malaise, and abdominal pain and distention could indicate a perforated bowel with peritonitis.

question
The gastrointestinal (GI) system (also called the digestive system)
answer
The mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. The associated organs are the liver, pancreas, and gallbladder
question
The GI is composed of four layers
answer
(1) mucosa, (2) submucosa, (3) muscle, and (4) serosa
question
The GI tract is innervated by the parasympathetic and sympathetic branches of the autonomic nervous system.
answer
The parasympathetic (cholinergic) system is mainly excitatory, and the sympathetic (adrenergic) system is mainly inhibitory. For example, peristalsis is increased by parasympathetic stimulation and decreased by sympathetic stimulation.
question
The GI tract has its own nervous system: the enteric (or intrinsic) nervous system.
answer
composed of two nerve layers that lie between the mucosa and the muscle layers. These neurons have receptors for pressure and movement.

question
two layers of the peritoneum
answer
the parietal layer, which lines the abdominal cavity wall, and the visceral layer, which covers the abdominal organs
question
The main function of the GI system is
answer
to supply nutrients to body cells. This is accomplished through the processes of (1) ingestion (taking in food), (2) digestion (breaking down food), and (3) absorption (transferring food products into circulation)
question
appetite
answer
stimulated by hypoglycemia, an empty stomach, decrease in body temperature, and input from higher brain centers. The sight, smell, and taste of food frequently stimulate appetite. Appetite may be inhibited by stomach distention, illness (especially accompanied by fever), hyperglycemia, nausea and vomiting, and certain drugs (e.g., amphetamines).
question
Ghrelin
answer
released from the stomach mucosa plays a role in appetite stimulation.
question
Leptin
answer
involved in appetite suppression
question
salivary glands
answer
parotid, submaxillary, and sublingual glands. These glands produce saliva, which consists of water, protein, mucin, inorganic salts, and salivary amylase.
question
The Stomach
answer
functions are to store food, mix food with gastric secretions, and empty contents in small boluses into the small intestine; absorbs only small amounts of water, alcohol, electrolytes, and certain drugs; always contains gastric fluid and mucus; serves as a reservoir for food, which is slowly released into the small intestine. The length of time that food remains in the stomach depends on the composition of the food, but average meals remain from 3 to 4 hours.
question
upper esophageal sphincter (UES)
answer
at the proximal end of the esophagus
question
lower esophageal sphincter (LES)
answer
remains contracted except during swallowing, belching, or vomiting; is an important barrier that normally prevents reflux of acidic gastric contents into the esophagus.
question
chief cells, located in the funds of the stomach
answer
which secrete pepsinogen, and parietal cells, which secrete hydrochloric (HCl) acid, water, and intrinsic factor. The secretion of HCl acid makes gastric juice acidic. This acidic pH aids in the protection against ingested organisms. Intrinsic factor promotes cobalamin (vitamin B12) absorption in the small intestine.
question
Small intestine
answer
two primary functions are digestion and absorption (uptake of nutrients from the gut lumen to the bloodstream). It extends from the pylorus to the ileocecal valve. Composed of the duodenum, jejunum, and ileum; carbohydrates are broken down to monosaccharides, fats to glycerol and fatty acids, and proteins to amino acids
question
The ileocecal valve
answer
prevents reflux of large intestine contents into the small intestine.
question
amylase (ptyalin)
answer
breaks down starches to maltose
question
digestion of proteins
answer
begins in the stomach with the release of pepsinogen from chief cells
question
chyme
answer
food mixed with gastric secretions; stimulate motility and secretion. Secretions involved in digestion include enzymes from the pancreas, bile from the liver and enzymes from the small intestine. Enzymes on the brush border of the microvilli complete the digestion process. These enzymes break down disaccharides to monosaccharides and peptides to amino acids for absorption.
question
Large intestin
answer
absorption of water and electrolytes; forms feces and serves as a reservoir for the fecal mass until defecation occurs
question
Liver
answer
largest internal organ in the body; It lies in the right epigastric region; it essential for life; It functions in the manufacture, storage, transformation, and excretion of a number of substances involved in metabolism.
question
The biliary tract
answer
consists of the gallbladder and the duct system.
question
The gallbladder
answer
It function is to concentrate and store bile. It holds approximately 45 mL of bile. Bile is produced by the hepatic cells
question
stercobilinogen
answer
accounts for the brown color of stool.
question
Functions of the Liver
answer
Carbohydrate metabolism; Glycogenesis (conversion of glucose to glycogen), glycogenolysis (process of breaking down glycogen to glucose), gluconeogenesis (formation of glucose from amino acids and fatty acids). Protein metabolism: Synthesis of nonessential amino acids, synthesis of plasma proteins (except gamma globulin), synthesis of clotting factors, urea formation from ammonia (NH3) (NH3 formed from deamination of amino acids by action of bacteria in colon). Fat metabolism: Synthesis of lipoproteins, breakdown of triglycerides into fatty acids and glycerol, formation of ketone bodies, synthesis of fatty acids from amino acids and glucose, synthesis and breakdown of cholesterol. Detoxification: Inactivation of drugs and harmful substances and excretion of their breakdown products. Steroid metabolism; Conjugation and excretion of gonadal and adrenal corticosteroid hormones. Bile Synthesis Bile production; Formation of bile, containing bile salts, bile pigments (mainly bilirubin), and cholesterol. Bile excretion: Bile excretion by liver about 1 L/day. Storage: Glucose in form of glycogen. Vitamins, including fat soluble (A, D, E, K) and water soluble (B1, B2, cobalamin, folic acid). Fatty acids. Minerals (iron, copper). Amino acids in form of albumin and beta-globulins. Kupffer cells: Breakdown of old RBCs, WBCs, bacteria, and other particles. Breakdown of hemoglobin from old RBCs to bilirubin and biliverdin.
question
The pancreas
answer
behind the stomach and in front of the first and second lumbar vertebrae; exocrine and endocrine functions. The exocrine function contributes to digestion through the production and release of enzymes. The endocrine function occurs in the islets of Langerhans, whose β cells secrete insulin and amylin; α cells secrete glucagon; δ cells secrete somatostatin; and F cells secrete pancreatic polypeptide.
question
Causes of constipation in older adults
answer
slower peristalsis, inactivity, decreased dietary fiber, decreased fluid intake, constipating medications, and laxative abuse; neurologic, cognitive, and metabolic disorders may also play a role.
question
Drug effect on the GI
answer
chronic high doses of acetaminophen and nonsteroidal antiinflammatory drugs (NSAIDs) may be hepatotoxic. NSAIDs (including aspirin) may also predispose a patient to upper GI bleeding, with an increasing risk as the person ages. Other medications such as antibiotics may change the normal bacterial composition in the GI tract, resulting in diarrhea. Antacids and laxatives may affect the absorption of certain medications.

question
An upper GI series with small bowel follow-through
answer
provides visualization of the oropharyngeal area, the esophagus, the stomach, and the small intestine via fluoroscopy and x-ray examination. The procedure consists of the patient swallowing contrast medium and then assuming different positions on the x-ray table.
question
lower GI series (barium enema)
answer
observe by means of fluoroscopy the colon filling with contrast medium and to observe by x-ray the filled colon. This procedure identifies polyps, tumors, and other lesions in the colon. It consists of administering an enema of contrast medium to the patient.
question
Esophagogastroduodenoscopy (EGD)
answer
Directly visualizes mucosal lining of esophagus, stomach, and duodenum with flexible endoscope. Before procedure: Keep patient NPO for 8 hr. Make sure signed consent is on chart. Give preoperative medication if ordered. Explain to patient that local anesthesia may be sprayed on throat before insertion of scope and that patient will be sedated during the procedure. After procedure: Keep patient NPO until gag reflex returns. Gently tickle back of throat to determine reflex. Use warm saline gargles for relief of sore throat. Check temperature q15-30min for 1-2 hr (sudden temperature spike is sign of perforation).
question
Colonoscopy
answer
Directly visualizes entire colon up to ileocecal valve with flexible fiberoptic scope. Before procedure: Bowel preparation is done. After procedure: Patient may experience abdominal cramps caused by stimulation of peristalsis because the bowel is constantly inflated with air during procedure. Observe for rectal bleeding and manifestations of perforation (e.g., malaise, abdominal distention, tenesmus). Check vital signs.
question
Video capsule endoscopy (VCE)
answer
Patient swallows a capsule with camera , which provides endoscopic visualization of GI tract . Instruct patient to fast overnight. Patient may have bowel preparation similar to colonoscopy. The video capsule is swallowed, and clear liquids resumed after 2 hr and food and medications after 4 hr. Eight hours after swallowing the capsule, the patient returns to have the monitoring device removed. Peristalsis causes passage of the disposable capsule with a bowel movement.
question
1.A patient is admitted to the hospital with a diagnosis of diarrhea with dehydration. The nurse recognizes that increased peristalsis resulting in diarrhea can be related to a.sympathetic inhibition. b.mixing and propulsion. c.sympathetic stimulation. d.parasympathetic stimulation.
answer
D
question
2.A patient has an elevated blood level of indirect (unconjugated) bilirubin. One cause of this finding is that a.the gallbladder is unable to contract to release stored bile. b.bilirubin is not being conjugated and excreted into the bile by the liver. c.the Kupffer cells in the liver are unable to remove bilirubin from the blood. d.there is an obstruction in the biliary tract preventing flow of bile into the small intestine.
answer
B Bilirubin is a pigment derived from the breakdown of hemoglobin and is insoluble in water. Bilirubin is bound to albumin for transport to the liver and is referred to as unconjugated. An indirect bilirubin determination is a measurement of unconjugated bilirubin, and the level may be elevated in hepatocellular and hemolytic conditions.
question
3.As gastric contents move into the small intestine, the bowel is normally protected from the acidity of gastric contents by the a.inhibition of secretin release. b.release of bicarbonate by the pancreas. c. release of pancreatic digestive enzymes. d. release of gastrin by the duodenal mucosa.
answer
B The hormone secretin stimulates the pancreas to secrete fluid with a high concentration of bicarbonate. This alkaline secretion enters the duodenum and neutralizes acid in the chyme.
question
4. A patient is jaundiced and her stools are clay colored (gray). This is most likely related to a.decreased bile flow into the intestine. b.increased production of urobilinogen. c.increased production of cholecystokinin. d.increased bile and bilirubin in the blood.
answer
A Bile is produced by the hepatocytes and is stored and concentrated in the gallbladder. When bile is released from the common bile duct, it enters the duodenum. In the intestines, bilirubin is reduced to stercobilinogen and urobilinogen by bacterial action. Stercobilinogen accounts for the brown color of stool. Stools may be clay-colored if bile is not released from the common bile duct into the duodenum. Jaundice may result if the bilirubin level in the blood is elevated.
question
5. An 80-year-old man states that, although he adds a lot of salt to his food, it still does not have much taste. The nurse's response is based on the knowledge that the older adult a.should not experience changes in taste. b.has a loss of taste buds, especially for sweet and salt. c.has some loss of taste but no difficulty chewing food. d.loses the sense of taste because the ability to smell is decreased.
answer
B Older adults have decreased numbers of taste buds and a decreased sense of smell. These age-related changes diminish the sense of taste (especially of salty and sweet substances).
question
6. When the nurse is assessing the health perception-health maintenance pattern as related to GI function, an appropriate question to ask is a."What is your usual bowel elimination pattern?" b."What percentage of your income is spent on food?" c."Have you traveled to a foreign country in the last year?" d."Do you have diarrhea when you are under a lot of stress?"
answer
C When assessing gastrointestinal function in relation to the health perception-health management pattern, the nurse should ask the patient about recent foreign travel with possible exposure to hepatitis, parasitic infestation, or bacterial infection.
question
7. During an examination of the abdomen the nurse should a.position the patient in the supine position with the bed flat and knees straight. b.listen in the epigastrium and all four quadrants for 2 minutes for bowel sounds. c.use the following order of techniques: inspection, palpation, percussion, auscultation. d.describe bowel sounds as absent if no sound is heard in the lower right quadrant after 2 minutes.
answer
B The nurse should listen in the epigastrium and all four quadrants for bowel sounds for at least 2 minutes. The patient should be in the supine position and should slightly flex the knees; the head of the bed should be raised slightly. During examination of the abdomen, the nurse auscultates before performing percussion and palpation because the latter procedures may alter the bowel sounds. Bowel sounds cannot be described as absent until no sound is heard for 5 minutes in each quadrant.
question
8. A normal physical assessment finding of the GI system is/are (select all that apply) a.nonpalpable liver and spleen. b.borborygmi in upper right quadrant. c.tympany on percussion of the abdomen. d.liver edge 2 to 4 cm below the costal margin. e. finding of a firm, nodular edge on the rectal examination.
answer
A, C Normal assessment findings for the gastrointestinal system include a nonpalpable liver and spleen and generalized tympany on percussion. Normally, bowel sounds are high pitched and gurgling; loud gurgles indicate hyperperistalsis and are called borborygmi (stomach growling). If the patient has chronic obstructive pulmonary disease, large lungs, or a low-set diaphragm, the liver may be palpated 0.4 to 0.8 inch (1 to 2 cm) below the right costal margin. On palpation, the rectal wall should be soft and smooth and should have no nodules.
question
9. In preparing a patient for a colonoscopy, the nurse explains that a.a signed permit is not necessary. b.sedation may be used during the procedure. c.only one cleansing enema is necessary for preparation. d.a light meal should be eaten the day before the procedure.
answer
B Sedation is induced during a colonoscopy. A signed consent form is necessary for a colonoscopy. A cathartic or enema is administered the night before the procedure, and more than one enema may be necessary. Patients may need to be kept on clear liquids 1 to 2 days before the procedure.
