1. A 62-year-old man with chronic anemia is experiencing increased fatigue and occasional palpitations at rest. The nurse would expect the patient's laboratory test findings to include
- A. an RBC count of 4,500,000/μL.
- B. a hematocrit (Hct) value of 38%.
- C. normal red blood cell (RBC) indices.
- D. a hemoglobin (Hgb) of 8.6 g/dL.
Correct answer: B
Rationale: The correct answer is B. In chronic anemia, the hematocrit (Hct) value is a crucial indicator of the proportion of red blood cells in the blood. A hematocrit value of 38% indicates a lower than normal level of red blood cells, which aligns with the patient's symptoms of fatigue and palpitations. Choices A, C, and D are incorrect because a low RBC count, normal RBC indices, and a hemoglobin level of 8.6 g/dL do not specifically address the decreased red blood cell mass associated with chronic anemia.
2. Which laboratory test will the nurse use to determine whether filgrastim (Neupogen) is effective for a patient with acute lymphocytic leukemia who is receiving chemotherapy?
- A. Platelet count
- B. Reticulocyte count
- C. Total lymphocyte count
- D. Absolute neutrophil count
Correct answer: D
Rationale: The correct answer is D, Absolute neutrophil count. Filgrastim (Neupogen) works by stimulating the production and function of neutrophils. Therefore, monitoring the Absolute neutrophil count is crucial to assess the effectiveness of filgrastim in increasing neutrophil levels. Choices A, B, and C are incorrect because platelet count, reticulocyte count, and total lymphocyte count do not directly reflect the effectiveness of filgrastim in increasing neutrophils, which are essential in fighting infections during chemotherapy.
3. A patient is being discharged after an emergency splenectomy following a motor vehicle crash. Which instructions should the nurse include in the discharge teaching?
- A. Check frequently for swollen lymph nodes.
- B. Watch for excessive bleeding or bruising.
- C. Take iron supplements to prevent anemia.
- D. Wash hands and avoid individuals who are ill.
Correct answer: D
Rationale: The correct answer is D. After a splenectomy, the patient is at an increased risk of infection, particularly from gram-positive bacteria. Washing hands and avoiding contact with individuals who are ill are crucial to reduce this risk. Choice A is incorrect because checking for swollen lymph nodes is not a priority after a splenectomy. Choice B is incorrect as while bleeding is a concern, it is more immediate post-operatively. Choice C is incorrect as iron supplements do not specifically relate to the risk of infection post-splenectomy.
4. A healthcare provider reviews the laboratory data for an older patient. The healthcare provider would be most concerned about which finding?
- A. Hematocrit of 35%
- B. Hemoglobin of 11.8 g/dL
- C. Platelet count of 400,000/μL
- D. White blood cell (WBC) count of 2800/μL
Correct answer: D
Rationale: A low white blood cell (WBC) count in an older patient is concerning as it indicates a potential compromise in the patient's immune function. White blood cells are crucial for fighting infections and a low count could lead to an increased risk of infections. Hematocrit, hemoglobin, and platelet count are important parameters to assess, but a low WBC count takes priority in this case due to its direct impact on immune health.
5. After a patient with pancytopenia undergoes a bone marrow aspiration from the left posterior iliac crest, which action would be important for the nurse to take?
- A. Elevate the head of the bed to 45 degrees.
- B. Have the patient lie on the left side for 1 hour.
- C. Apply a sterile 2-inch gauze dressing to the site.
- D. Use a half-inch sterile gauze to pack the wound.
Correct answer: B
Rationale: After a bone marrow aspiration, it is important to have the patient lie on the left side for 30 to 60 minutes to decrease the risk of bleeding. Elevating the head of the bed to 45 degrees does not directly address the risk of bleeding. Applying a sterile 2-inch gauze dressing to the site is important for wound care but does not specifically address post-procedural positioning. Using a half-inch sterile gauze to pack the wound is not necessary after a bone marrow aspiration.
