The nurse is caring for a client diagnosed with angina. Which finding indicates a therapeutic effect of antianginal drug therapy?

Blood pressures be monitored regularly at home: Monitoring blood pressure at home helps the client track the effectiveness of antihypertensive therapy and detect trends that may require dose adjustments. It promotes early recognition of uncontrolled hypertension and allows timely communication with the healthcare provider.

• A low-sodium diet is recommended: Excess sodium intake contributes to fluid retention and increased blood pressure. Educating the client about reducing sodium supports medication efficacy and helps manage hypertension. Dietary modifications complement pharmacologic therapy to improve cardiovascular outcomes.

• Do not stop taking the medication abruptly: Abrupt discontinuation of antihypertensive medications can lead to rebound hypertension, which may cause stroke, myocardial infarction, or other cardiovascular complications. Clients should be educated to taper medications only under the guidance of a healthcare provider.

• Engage in regular exercise: Regular physical activity helps lower blood pressure by improving cardiovascular efficiency, reducing weight, and promoting vascular health. Exercise is an essential nonpharmacologic strategy that complements antihypertensive therapy and supports long-term blood pressure control.

A. Heart failure: Terazosin is not primarily indicated for heart failure management. While it may have some vasodilatory effects that could theoretically reduce afterload, it is not a standard treatment for heart failure and does not address the core pathophysiology.

B. Peripheral vascular disease: Terazosin does not directly treat peripheral vascular disease. Its mechanism of action as an alpha-1 adrenergic blocker primarily targets vascular smooth muscle to lower systemic blood pressure rather than improve blood flow to peripheral tissues.

C. Pulmonary edema: Pulmonary edema is usually managed with diuretics, oxygen therapy, and addressing the underlying cause. Terazosin does not have an acute role in managing fluid overload or pulmonary congestion.

D. Chronic hypertension: Terazosin is an alpha-1 adrenergic blocker used to treat chronic hypertension by relaxing vascular smooth muscle, reducing peripheral vascular resistance, and lowering blood pressure. It is commonly prescribed for long-term blood pressure control, especially in clients who may also have benign prostatic hyperplasia.
