A. By reducing clotting factors.
B. By decreasing blood pressure.
C. Relieving pain.
D. Dilating blood vessels.
Answer: D. Dilating blood vessels.
Nitroglycerin is a potent vasodilator (increases diameter of blood vessels). It works in seconds to relax the muscles of the blood vessel walls. This action dilates arteries creasing the blood flow through the coronary arteries and oxygen supply to the heart muscle and decreasing the workload of the heart. Decreasing blood pressure and pain relief are results of nitroglycerin action. It does not affect clotting factors.
