Why do you give nitroglycerin to a patient complaining of chest pain?

It takes their mind off the chest pain.
It dilates the bronchioles making it easier to breath.
It dilates the coronary arteries easing blood flow.
It dilates the pupils making it easier to see.

Explanation

Answer: C -The primary reason that patients are given nitroglycerin is to dilate the coronary arteries, which in turn lessens the workload on the heart by increasing blood flow. Nitroglycerine has a secondary, or side, effect of dilating peripheral vasculature and lowering systemic blood pressure, but its primary target is the coronary vasculature and increasing blood flow and therefor oxygen directly to the myocardium.
