You are transporting a patient who had an episode of chest pain. On scene, you assisted him in taking his nitroglycerin medication, which completely alleviated the chest pain. En route to the hospital, the patient asks you why the nitroglycerin took the chest pain away. Beyond telling the patient that nitroglycerin can increase coronary artery blood flow, you would add:

A) "It causes the heart rate to decrease, which relaxes it and decreases pain." B) "It has a sedative effect on the brain, making you less aware of the pain." C) "It dilates the blood vessels, which decreases the workload of the heart." D) "It causes the body to relax, decreasing the need for oxygen."
