The nurse notes that the client has a low red blood cell count and anticipates which of the following subjective manifestations on assessment? 1.Chest pain 2.Nausea 3.Sore throat 4. Fatigue

Answer:Fatigue Rationale: Fatigue would signify that the body’s tissues are not receiving enough oxygenation. Sore throat is a sign of infection. Chest pain may indicate an impending myocardial infarction. Nausea is a symptom for many disease processes, but is not typical for anemia.

p. 866, Safe and Effective Care Environment Which laboratory blood test result for a client undergoing hematologic assessment does the nurse report immediately to the prescriber? A. Red blood cell count 1.2 million/mm3 B. Platelets 185,000/mm3 C. Hematocrit 36% D. INR 1.2

ANS: A Rationale: All of these test results are in the low to low-normal range. However, the most abnormal result is the red blood cell count. The normal red blood cell range is 4.2 to 6.1 million/mm3. This client’s value is dangerously below normal. More test answers on https://studyhippo.com/ch-41-42-hematology-nclex-review/

The nurse expects which of these laboratory test results to be elevated in a client following an acute myocardial infarction? a) creatine kinase (CK), troponin T and I, and myoglobin b) blood urea nitrogen (BUN), serum creatinine, and protein-bound iodine c) aspartate aminotransferase (AST) [formerly serum glutamic-oxalaocteic transaminase (SGOT)], red blood cell count (RBC), and platelets d) lactic dehydrogenase (LDH), thyroxine, and endorphin levels (Kaplan, Cardio B 5/30)

a) values are increased after an MI; creatine kinase (CK-MB) is an enzyme that is cardiac specific; begins to increase in an hour and peaks in 24 hours; troponin is myocardial muscle protein released when heart muscle is damaged; any rise indicates MI; myoglobin is protein found in cardiac and skeletal muscle; normal is less than 90 micrograms/L (Kaplan, Cardio B 5/30) More test answers on https://studyhippo.com/kaplan-cardio-set-b/

3. A full-term neonate who is 30 hours old has a bilirubin level of 10 mg/dL. The neonate has a yellowish tint to the skin of the face. The mother is breastfeeding her newborn. The nurse caring for this neonate would anticipate which of the following interventions? a. Phototherapy b. Feeding neonate every 2 to 3 hours c. Switch from breastfeeding to bottle feeding d. Assess red blood cell count

ANS: b a. Phototherapy is considered when the levels are 12 mg/dL or higher when the neonate is 25 to 48 hours old. Neonates re-absorb increased amounts of unconjugated bilirubin in the intestines due to lack of intestinal bacteria and decreased gastrointestinal motility. b. Adequate hydration promotes excretion of bilirubin in the urine. c. Colostrum acts as a laxative and assists in the passage of meconium. d. Assessing RBC is not a treatment for hyperbilirubinemia.

What is Red Blood Cell Count?

Red Blood Cell Count is a test used to measure the number of red blood cells in a sample of your blood. It is also known as an RBC count. This test helps diagnose and monitor many different conditions, such as anemia, polycythemia, or leukemia. It can also help detect infection or other serious medical conditions. The RBC count provides valuable information about your overall health and can help guide treatment decisions.The RBC count measures the number of red blood cells present in a given volume of your blood sample. Red blood cells are responsible for carrying oxygen throughout your body, so having an accurate measurement is important for assessing overall health and detecting any potential issues. In general, a normal range for adults is 4 million to 6 million red blood cells per milliliter (mm3) of whole blood. An abnormally low level may indicate anemia or a recent loss of red blood cells due to bleeding; while an abnormally high level may indicate dehydration or polycythemia (a condition in which the body produces too many red blood cells).Your doctor may order this test if you are experiencing signs and symptoms that could be related to one of the above conditions, such as fatigue, shortness of breath or pale skin tone. The results can provide important insight into whether further testing or treatment is needed to address the underlying cause behind these symptoms. Your doctor may also order this test periodically if you have been diagnosed with any condition that affects your red cell production or distribution within the body, such as sickle cell disease or thalassemia (a type of inherited anemia). To collect a sample for this test, your healthcare provider will draw some blood from one arm using either a needle and syringe method or finger prick technique; depending on what type of analysis they need performed on the sample. After drawing it up into collection tubes containing preservatives and anticoagulants (to prevent clumping), they will send it off to be processed at their lab’s certified facility where technicians will use specialized equipment and techniques to identify each individual cell type present in the sample before counting them up manually under microscopes with calibrated slides in order to determine how many there are per mm3of whole-blood volume collected from you during sampling procedure then report back those findings directly back to your doctor who ordered it initially so they can decide upon best course(s) of action based off those exact results.
