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.

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.

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.

Correct Answer: A

Rationale: Rationale: 1. Allopurinol inhibits xanthine oxidase enzyme, reducing uric acid levels. 2. Probenecid increases uric acid excretion, not inhibiting xanthine oxidase. 3. Colchicine is an anti-inflammatory agent for gout, not a xanthine oxidase inhibitor. 4. Leflunomide is a disease-modifying antirheumatic drug, not a xanthine oxidase inhibitor. In summary, Allopurinol (choice A) is the correct answer as it directly inhibits xanthine oxidase, while the other choices have different mechanisms of action not related to xanthine oxidase inhibition.

Correct Answer: D

Rationale: The correct answer is D because abruptly stopping prednisone can lead to adrenal insufficiency due to suppression of the body's natural cortisol production. This can result in potentially life-threatening symptoms. Choices A, B, and C are incorrect because while they are important considerations when taking prednisone, they are not as critical as ensuring the client understands the importance of tapering off the medication gradually to prevent adrenal insufficiency.
