Which of the following best describes the effects of nitroglycerin?

A. Peripheral artery vasodilation
B. Coronary artery vasodilation
C. Chronic migraines
D. Peripheral vein vasodilation

Answer :

The best description of the effects of nitroglycerin is: Peripheral vein vasodilation.

Nitroglycerin primarily causes venous dilation, which reduces the amount of blood returning to the heart (preload), lowering the workload on the heart.

This helps relieve symptoms of angina by decreasing myocardial oxygen demand. While it also dilates coronary arteries to some extent, its primary action is on peripheral veins.

Nitroglycerin is not typically used for chronic migraines, and its effect on peripheral arteries is less pronounced than on veins.
