Final answer:
Epinephrine is not typically included in the ED general treatment for chest pain, whereas aspirin, morphine, and nitroglycerin are commonly used for their clot-preventive, pain-relieving, and vasodilating effects, respectively.
Step-by-step explanation:
Among the options listed for the general treatment of chest pain in the emergency department (ED), Epinephrine is not typically included. The mainstays of emergency treatment for chest pain, particularly due to acute myocardial infarction (MI), include administering aspirin, which helps to break up clots, morphine for pain control, and nitroglycerin, which is used to relieve chest pain associated with angina by vasodilation and improving blood flow to the heart muscle. Nitroglycerin has been used since the 1880s and continues to be a critical medication in the treatment of heart-related chest pain. While Epinephrine can increase blood pressure and heart rate, it is not a standard treatment for chest pain mainly because it can actually exacerbate ischemia in patients with coronary artery disease.
