Which dietary recommendation aligns with the DASH diet for Mr. Carter?

Choice A reason: Shiny skin is associated with peripheral arterial disease due to reduced blood flow causing trophic changes. Peripheral venous disease causes venous stasis, leading to swollen veins and edema, not shiny skin. This finding is incorrect, as it reflects arterial insufficiency rather than venous pathology in the lower extremities.

Choice B reason: Swollen and enlarged veins are hallmark manifestations of peripheral venous disease, resulting from venous stasis and incompetent valves, causing blood pooling and varicosities. This increases venous pressure, leading to visible vein enlargement, making this the primary finding the nurse should recognize in clients with this condition.

Choice C reason: Diminished hair growth is characteristic of peripheral arterial disease, where reduced arterial flow impairs follicle nourishment. Peripheral venous disease causes edema and varicosities, not hair loss. This finding is incorrect, as it reflects arterial, not venous, pathology, making it irrelevant to the client’s condition.

Choice D reason: Loss of pigmentation over the shin suggests arterial insufficiency or chronic venous stasis dermatitis with hyperpigmentation, not depigmentation. Peripheral venous disease typically causes brownish discoloration from hemosiderin. This finding is incorrect, as swollen veins are more specific to venous disease than pigmentation changes.

Choice A reason: Stopping beta blockers abruptly if fatigue occurs is dangerous, as it can cause rebound hypertension or arrhythmias. Fatigue is a common side effect, but patients should consult providers, making this incorrect, as the nurse should teach safe management, not sudden discontinuation.

Choice B reason: Beta blockers are not used for quick relief in hypertensive emergencies, which require rapid-acting drugs like nitroprusside. They manage chronic hypertension, making this incorrect, as the nurse should clarify their role in long-term control, not acute crisis management.

Choice C reason: Grapefruit juice affects some cardiac drugs but not beta blockers significantly, and it does not enhance absorption. This is incorrect, as the nurse should focus on side effects like bradycardia, not irrelevant drug-food interactions, for effective beta blocker patient education.

Choice D reason: Beta blockers slow heart rate by blocking beta-adrenergic receptors, potentially causing bradycardia. This is a major teaching point, as patients must monitor for symptoms like dizziness, making it the correct choice to include in education for safe beta blocker use.
