Correct Answer: B

Rationale: The correct instruction for the nurse to provide to the client prescribed atorvastatin (Lipitor) for hyperlipidemia is to avoid drinking grapefruit juice while taking this medication. Grapefruit juice can interfere with the metabolism of atorvastatin, leading to an increased risk of side effects. It is crucial for the client to adhere to this instruction to ensure the effectiveness and safety of the treatment. Choices A, C, and D are incorrect because taking the medication with breakfast, increasing dietary fiber intake, and avoiding foods high in potassium are not specific instructions related to atorvastatin therapy for hyperlipidemia.

Correct Answer: B

Rationale: Spinach is high in vitamin K, which can interfere with the effectiveness of warfarin. It is important for clients taking warfarin to maintain consistent levels of vitamin K intake to ensure the medication works properly. Foods rich in vitamin K, such as spinach, can counteract the effects of warfarin, leading to potential complications. Therefore, clients on warfarin are advised to either avoid or consume vitamin K-rich foods, like spinach, in consistent amounts to maintain the medication's efficacy. Bananas, oranges, and yogurt are not high in vitamin K and do not significantly impact the effectiveness of warfarin, making them safe options for clients taking this medication.

Correct Answer: B

Rationale: In a client with coronary artery disease (CAD) experiencing dyspnea at rest, the priority intervention should be to elevate the head of the bed to at least 45 degrees. This position helps reduce the work of breathing, optimizes lung expansion, and can alleviate symptoms of dyspnea by improving oxygenation and ventilation. Providing a walker for ambulation, monitoring oxygen saturation, and having an oxygen cannula at the bedside are important interventions but not the priority when the client is experiencing dyspnea at rest. Elevating the head of the bed is crucial to improve respiratory function and should be prioritized in this situation.

Correct Answer: A

Rationale: Corrected Rationale: When taking docusate sodium, it is important to take the medication with a full glass of water to help ensure its proper effectiveness. This helps prevent the stool from hardening and makes it easier to pass, especially for individuals experiencing constipation. Choice B is incorrect because there is no specific instruction to take docusate sodium at bedtime. Choice C is incorrect because docusate sodium does not need to be taken on an empty stomach. Choice D is incorrect because there is no need to avoid taking docusate sodium with antacids.

Correct Answer: A

Rationale: Limiting alcohol intake is an essential lifestyle modification recommended for managing hypertension. Excessive alcohol consumption can raise blood pressure, so limiting it to one drink per day is beneficial in controlling hypertension. Alcohol moderation is a key part of a heart-healthy lifestyle for individuals with high blood pressure. Choice B is incorrect because increasing sodium intake can actually worsen hypertension by retaining water and increasing blood pressure. Choice C is incorrect because while exercise is important for overall health, moderate-intensity exercise is recommended for individuals with hypertension to avoid excessive strain on the heart. Choice D is incorrect because high potassium foods like bananas are actually beneficial for individuals with hypertension as they can help lower blood pressure.
