Multiple Choice Questions on Immune System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
Which of the following is a consideration when administering salicylates?
Correct Answer: A
Rationale: The correct answer is A because administering salicylates with food, milk, antacids, or a large glass of water helps to minimize gastrointestinal side effects like stomach irritation and ulcers. Salicylates can be harsh on the stomach lining, so taking them with food or a buffer like milk or antacids can reduce irritation. Administering on an empty stomach (choice B) can increase the risk of stomach irritation. Crushing enteric-coated tablets (choice C) can lead to rapid absorption and increase the risk of side effects. Avoiding taking with water (choice D) is incorrect as water can help with swallowing and absorption.
Question 5 of 5
What is a consideration for patients taking methotrexate?
Correct Answer: A
Rationale: The correct answer is A because methotrexate can cause bone marrow suppression, leading to decreased production of blood cells and increased risk of infections. Monitoring for signs of infection is crucial to detect and manage any complications promptly. Choice B is incorrect as methotrexate is usually taken on an empty stomach. Choice C advising to avoid taking with water is irrelevant. Choice D is incorrect as methotrexate is typically administered on an empty stomach to enhance absorption.
