C. "You must take prophylactic analgesics just before engaging in the planned exer-cise."
D. "You must take prophylactic potassium chloride just before engaging in the planned exercise."

Participation in exercise may increase myocardial oxygen demand beyond the ability of the co-ronary circulation to deliver enough oxygen to meet the increased need. Nitroglycerin dilates coronary arteries within 5 minutes of use, ensuring that they will be ready to meet the demand during exercise.
