Quizplus · Accepted Answer

IV nitroglycerin is a vasodilator that primarily affects the veins, leading to decreased preload and improved myocardial oxygen supply. Relief of pain is an expected outcome of its administration as it can decrease myocardial workload and the resulting ischemia that causes chest pain in patients with MI. Decreased heart rate, increased cardiac output, and control of cardiac dysrhythmias are not expected outcomes of nitroglycerin administration, although they may occur secondary to the medication's actions.
