The patient is taking phenelzine (Nardil). The nurse teaches her to avoid eating:

A. ACE inhibitors may be started later to manage heart failure or hypertension after a heart attack but are not typically given acutely during a myocardial infarction.

B. Thrombolytics, such as alteplase, are given as soon as possible after a heart attack to dissolve the blood clot causing the blockage in the coronary artery.

C. Aspirin is commonly administered during a heart attack to help prevent further clot formation and reduce the risk of complications.

D. Potassium-sparing diuretics are not typically given during a myocardial infarction but may be used later in the management of heart failure.

E. Beta blockers are commonly given during and after a heart attack to reduce the heart's workload, decrease oxygen demand, and improve survival rates.

A. Organic nitrates, such as nitroglycerin, dilate (widen) veins and coronary arteries, leading to decreased preload and afterload, which helps relieve angina pain.

B. Constricting veins and coronary arteries would exacerbate angina symptoms by reducing blood flow to the heart muscle.

C. Dissolving veins and coronary arteries is not a mechanism of action for organic nitrates in the treatment of angina.

D. Dilating veins and coronary arteries is the primary mechanism of action for organic nitrates, resulting in increased blood flow to the heart muscle and relief of angina pain.
