A 60-year-old man presents with chest pain and difficulty breathing. He is pale, diaphoretic, and in severe pain. As your partner applies supplemental oxygen, you assess his vital signs. His blood pressure is 180/90 mm Hg, pulse is 110 beats/min and irregular, and respirations are 24 breaths/min and labored. You ask him if has taken any nitroglycerin and he tells you that he does not have any but his wife does. You should:

A: contact medical control and request permission to assist the patient with up to three doses of his wife's nitroglycerin. B: transport at once, apply the AED in case he develops cardiac arrest, and monitor his vital signs en route to the hospital. C: have him swallow up to four enteric-coated aspirin, continue oxygen therapy, and promptly transport him to the hospital. D: complete your focused physical examination and prepare the patient for immediate transport to an appropriate hospital.
