The correct answer is D.  

This scenario presents some atypical signs of a heart attack that may be present in women, the elderly, and patients with diabetes.  This woman has no history of heart disease, but her chest pain is a "red flag" for heart attack.  Your response to this woman should be the same as that for someone at high risk: tell her to lie down or sit quietly, then you phone 911 immediately.  If the woman were at high risk, with a history of heart disease and a prescription for nitroglycerin.  your response would be to help her take one of her nitroglycerin tablets at 3- to 5-minute intervals (up to a maximum of 3 tablets) and phone 911 if the pain persists.  

Answer a is incorrect because although it may be a good idea to give aspirin to a victim of heart attack, you should not delay phoning 911 to allow the victim to rest for an hour.  The risk of arrhythmias and death is highest in patients with myocardial infarction (heart attack) during the first hour after the onset of symptoms - this is the time that the victim is most in need of EMS support.  

Answer b is incorrect because a call to the victim's personal physician will waste time and delay transport of the victim to an Emergency Department.  EMS personnel will be prepared to treat sudden arrhythmias that may develop during transport, and they can provide pre-arrival notification to the receiving hospital to speed care at the hospital.  

Answer c is incorrect because any form of exertion, including walking, is contraindicated in a patient who may be experiencing a heart attack.  In addition, you should not delay-phone 911!
