Final answer:
Administer aspirin per protocol to break up clots and prioritize transport to the hospital for nitroglycerin administration.
Step-by-step explanation:
In this situation, it is important to prioritize the immediate treatments for a potential myocardial infarction (MI) or heart attack. Giving aspirin per protocol is a crucial step because it helps to break up clots that may be blocking the arteries and causing the tightness in the patient's chest. Nitroglycerin is also important in restoring blood flow as it causes the blood vessels to dilate. However, given the short transport time to the hospital and the fact that nitroglycerin has not been taken by the patient, it may be more appropriate to prioritize transport and administer nitroglycerin once the patient is at the hospital.
