Correct Answer: A

Rationale: The correct answer is A: Weight-bearing exercise. Weight-bearing exercise helps build and maintain bone density, which is critical in preventing osteoporosis. Activities like aerobic exercises, stretching, and low-impact exercises such as swimming are beneficial for overall fitness but do not directly contribute to improving bone strength, making them less effective in preventing osteoporosis.

Correct Answer: A

Rationale: The correct answer is A: Non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs can increase the risk of bleeding in clients taking Coumadin, which is an anticoagulant medication. Avoiding NSAIDs helps prevent potentially dangerous interactions with Coumadin. Choices B, C, and D are incorrect. Cough medicines with guaifenesin, histamine blockers, and laxatives containing magnesium salts do not typically have significant interactions with Coumadin therapy. Therefore, they are not the over-the-counter medications that the client needs to avoid while on Coumadin.

Correct Answer: C

Rationale: A potassium level of 6.2 mEq/L indicates hyperkalemia, which is dangerous and requires immediate treatment. Administering a potassium-binding medication will help lower potassium levels and prevent life-threatening complications.

Correct Answer: D

Rationale: In this situation, the client's pruritus (itching) is likely exacerbated by hot baths, which can worsen the itching sensation. Using cooler water will help soothe the skin and reduce pruritus. Additionally, applying calamine lotion after soaking can provide further relief. Instructing the client to use a moisturizer immediately after the bath (Choice A) may not address the root cause of pruritus aggravated by hot baths. Advising the client to take shorter baths with less water (Choice B) might not be as effective in relieving the itching sensation caused by cirrhosis. Suggesting antihistamines for the pruritus (Choice C) may not directly address the impact of hot baths on the client's discomfort.

Correct Answer: D

Rationale: The correct answer is D, 'All of the above.' When developing educational materials for older clients with new antihypertensive medications, it is essential to include characteristics such as using pictures to illustrate complex ideas, providing a list with definitions of unfamiliar terms, and using common words with few syllables. These features help enhance understanding and medication adherence, especially for older adults who may have challenges with health literacy. Choices A, B, and C collectively address the need for simplicity, visual support, and clarification of terms in educational materials, making them crucial for effective patient education.
