The primary goal of pharmacotherapy in coronary artery disease is to:

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.

Choice A rationale

While adequate fluid intake is important for overall health, it does not directly counteract the sedative or unsteady side effects of an anxiolytic medication. Increasing fluid intake will not improve drowsiness or unsteadiness caused by central nervous system depression, and it is not a standard or effective nursing intervention for these specific adverse effects.

Choice B rationale

Anxiolytics, particularly benzodiazepines, are central nervous system depressants that cause drowsiness and impair coordination and judgment. Due to the sedative effects and potential for unsteadiness and ataxia, it is crucial to advise patients to avoid activities that require alertness and precise motor skills, such as driving or operating heavy machinery, to prevent accidents.

Choice C rationale

Alcohol and anxiolytics are both central nervous system depressants. Taking them together has a synergistic effect, meaning their combined depressive effects are greater than the sum of their individual effects. This can significantly increase the risk of severe drowsiness, respiratory depression, and even coma or death. Patients must be warned to avoid alcohol completely.

Choice D rationale

Abruptly discontinuing an anxiolytic, especially a benzodiazepine, can lead to severe withdrawal symptoms, including rebound anxiety, insomnia, tremors, and even seizures. The medication should not be stopped immediately by the patient without consulting a healthcare provider. The dose should be tapered slowly under medical supervision to prevent these dangerous effects.

Choice E rationale

While light exercise can be beneficial for mood and anxiety, it is not a primary or safe recommendation for a patient experiencing drowsiness and unsteadiness due to anxiolytic medication. Engaging in physical activity while feeling unsteady could increase the risk of falls and injury. The priority is to ensure the patient's safety by avoiding risky activities.
