An 85-year-old male with a history of heart attacks has called 911 for chest discomfort. He states that the pain started 2 hours ago when he was sitting on his porch. When asked, he states that it feels similar to his last heart attack, only this time he is also dizzy. The primary assessment indicates no life threats, and the Emergency Medical Responder on scene reports the following vital signs: pulse, 92 beats/min; respirations, 18 breaths/min; blood pressure, 88/52 mmHg; and SpO2, 92% on room air. The patient has nitroglycerin, but has not taken it yet (you have a standing order to administer nitroglycerin without calling medical direction). After applying oxygen, you should:

A) Perform the secondary exam
B) Assist the patient with his nitroglycerin
C) Provide nonemergent transport
D) Assess for neurologic deficits
