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

A. Aspirin is not primarily used to inhibit peptic ulcer disease; it is used to prevent cardiovascular events by decreasing platelet aggregation.

B. Aspirin decreases platelet aggregation, making it useful in preventing clot formation in conditions such as angina and myocardial infarction.

C. Aspirin is not used to reduce emphysema; it is primarily used for its antiplatelet effects.

D. Aspirin does not directly decrease carbon dioxide retention; its primary mechanism of action in cardiovascular disease is through antiplatelet effects.

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.
