You are assessing a 49-year-old man who complains of chest pressure that began the night before. He is conscious, but anxious, and tells you he has a history of angina and hypertension. After applying high-flow oxygen, you expose his chest to auscultate his lungs and note that he has a nitroglycerin patch on his right upper chest. His skin is cool and pale, his blood pressure is 78/50 mm Hg, and his pulse is 110 beats/min and irregular. You should:. A. remove the nitroglycerin patch, place him in a supine position and elevate his lower extremities, and prepare for immediate transport.
B. immediately remove the nitroglycerin patch, apply the AED in case he develops cardiac arrest, and transport to the closest hospital.
C. move the nitroglycerin patch to the other side of his chest in case you need to apply the AED, keep him warm, and transport without delay.
D. ask him if the nitroglycerin patch he is wearing has improved his chest pressure, complete your secondary assessment, and transport promptly.
