Multiple Choice Questions on Immune System Questions
Question 1 of 5
Which of the following statements is false?
Correct Answer: B
Rationale: The correct answer is B because hematopoietic stem cells give rise to all blood cell types, including both white and red blood cells. The other choices are true: A is correct as hematopoiesis does occur in various locations, C is true as hematopoietic stem cells can self-renew, and D is accurate as platelets do participate in clotting to prevent blood loss. Overall, B is the only statement that is false in this context.
Question 2 of 5
Which nutrient is necessary for erythropoiesis? Select one that does not apply.
Correct Answer: B
Rationale: The correct answer is B: Vitamin C. Vitamin C is not necessary for erythropoiesis, the process of red blood cell production. Iron is essential for hemoglobin synthesis, Vitamin B12 is needed for DNA synthesis in red blood cells, and Folic acid is crucial for cell division and growth in erythropoiesis. Vitamin C plays a role in collagen production and immune function, but it is not directly involved in red blood cell formation.
Question 3 of 5
Which nursing care should be prioritized when caring for a patient recovering from a bone marrow biopsy? Select one that does not apply.
Correct Answer: C
Rationale: The correct answer is C: Administer sedatives. Administering sedatives is not a priority when caring for a patient recovering from a bone marrow biopsy because sedatives are not typically needed for this procedure. The priority nursing care should focus on assessing for excess bleeding (A), providing analgesics for pain relief (B), and monitoring vital signs (D) to ensure the patient's safety and recovery. Sedatives may not be necessary and could potentially mask important signs or symptoms that need immediate attention. Prioritizing the assessment for bleeding, pain management, and monitoring vital signs ensures the patient's well-being and identifies any complications early on.
Question 4 of 5
A nurse is caring for a client who is postoperative following vein ligation and stripping for varicose veins. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct answer is A. Positioning the client supine with legs elevated helps promote venous return and reduce swelling in postoperative varicose veins. Elevating the legs assists in decreasing venous pressure, improving blood flow back to the heart. Keeping legs flat can lead to increased swelling and discomfort. Applying heat can exacerbate swelling and should be avoided. Immediate ambulation is not recommended initially postoperatively to prevent strain on the surgical site.
Question 5 of 5
A nurse is assessing a client for manifestations of aplastic anemia. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: The correct answer is A: Petechiae and ecchymosis. In aplastic anemia, there is a decrease in all types of blood cells (red blood cells, white blood cells, and platelets), leading to symptoms like easy bruising (ecchymosis) and tiny red or purple spots on the skin (petechiae) due to decreased platelet count. Pallor alone (B) is more indicative of anemia in general, not specifically aplastic anemia. Fever (C) is not a typical manifestation of aplastic anemia. Fatigue alone (D) is a common symptom of many types of anemia, but it does not specifically point to aplastic anemia.
