For a patient on antihypertensive medication, what lifestyle modification should the nurse recommend to enhance medication effectiveness?

Choice A rationale Reducing physical activity is not a recommended lifestyle modification for enhancing the effectiveness of antihypertensive medication. Regular physical activity, such as aerobic exercise, strengthens the cardiovascular system, helps manage weight, and can directly lower blood pressure, thereby complementing the effects of medication. Choice B rationale Increasing dietary sodium intake is detrimental to blood pressure control. High sodium intake leads to increased fluid retention, which raises blood volume and cardiac output, thereby increasing blood pressure. This counteracts the effect of antihypertensive medication and is a known risk factor for cardiovascular disease. Choice C rationale Limiting fluid intake is not a universally recommended strategy for all patients on antihypertensive medication. While some conditions like heart failure may require fluid restriction, this is not a general rule for hypertension management. Maintaining adequate hydration is important for overall health and for the proper function of various bodily systems. Choice D rationale Maintaining a low-sodium diet and managing weight are two critical lifestyle modifications that enhance the effectiveness of antihypertensive medication. A low-sodium diet reduces fluid retention and blood volume, while weight management decreases the strain on the heart and blood vessels. These actions work synergistically with medication to lower blood pressure.
