Multiple Choice Questions on Immune System Questions
Question 1 of 5
The nurse is caring for someone with a low red blood cell (erythrocyte) count. The nurse explains the function of the erythrocyte is to (select ONE that apply.)
Correct Answer: B
Rationale: Step 1: Erythrocytes carry oxygen bound to hemoglobin. This is correct as they transport oxygen from the lungs to the body tissues. Step 2: Erythrocytes also carry some carbon dioxide. This is the correct answer because they pick up carbon dioxide from the tissues and transport it to the lungs for exhalation. Step 3: Erythrocytes do not assist with clotting, which is primarily the role of platelets and certain proteins in the blood. Step 4: Erythrocytes do not assist with immunity, as that function is mainly carried out by white blood cells.
Question 2 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 3 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 4 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 5 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.
