Correct Answer: D

Rationale: The correct response is to explore the client's decision to refuse treatment and offer support. In this situation, it is crucial for the nurse to respect the client's autonomy and decisions regarding her own health. By exploring the client's reasons for refusal, the nurse can better understand her perspective and provide appropriate support. Option A is incorrect as it focuses on questioning the client in front of her children, potentially pressuring her. Option B is inappropriate as it disregards the client's autonomy and tries to persuade her to participate. Option C is also incorrect as it dismisses the client's decision and fails to address the family's concerns in a supportive manner.

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.

Correct Answer: D

Rationale: When administering diazepam for a client with alcohol withdrawal symptoms, it is crucial to perform ongoing assessment of respiratory status. Diazepam can lead to respiratory depression, emphasizing the need for continuous monitoring to detect any signs of respiratory distress early. Protecting the medication from light exposure is a general guideline for some drugs but is not a specific concern for diazepam. Observing for bruising or bleeding is not directly associated with the administration of diazepam for alcohol withdrawal symptoms, making choices A and C incorrect.

Correct Answer: B

Rationale: Confusion is a key symptom of Wernicke's syndrome, which is due to thiamine deficiency. Wernicke's syndrome is characterized by a triad of symptoms known as the classic triad, which includes confusion, ataxia, and ophthalmoplegia. Right lower abdominal pain, depression, and peripheral neuropathy are not typically associated with Wernicke's syndrome, making them incorrect choices for this question.

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.
