Correct Answer: C

Rationale: The correct answer is to keep nitroglycerin in a light-colored container and readily available. Nitroglycerin should be protected from light to maintain its effectiveness. Option A is incorrect because physical exercise immediately before eating can trigger angina. Option B is incorrect as cold weather can exacerbate angina symptoms. Option D is incorrect as isometric exercises can increase the workload on the heart, which is not recommended for individuals with angina.

Correct Answer: B

Rationale: The correct answer is B: 'Improve the function of the immune system.' Initiating interventions focusing on good nutrition, rest, exercise, and stress reduction aims to enhance the immune system function in clients with HIV infection. For individuals with HIV, maintaining a strong immune system is crucial in fighting the virus and preventing opportunistic infections. Choices A, C, and D are important aspects of care but are secondary to the primary goal of boosting the immune system to combat the effects of the HIV virus.

Correct Answer: C

Rationale: The correct answer is C. When a client experiences syncope due to a significant drop in blood pressure after receiving multiple antihypertensive medications, the additive effect of these medications can cause the blood pressure to drop excessively. This additive effect can lead to hypotension, which is why the nurse decided to hold the client's scheduled antihypertensive medication. Choices A, B, and D provide incorrect rationales. Choice A mentions diuresis, which is not directly related to the drop in blood pressure due to additive medication effects. Choice B refers to an antagonistic interaction reducing effectiveness, which is not applicable in this scenario. Choice D talks about a synergistic effect leading to drug toxicity, which is not the cause of the sudden drop in blood pressure observed in the client.
