A nurse on a medical-surgical unit is caring for a client who reports pain in the jaw, back, and shoulder with shortness of breath and nausea. Which of the following actions should the nurse take?

Choice A reason: Symptoms like jaw, back, and shoulder pain with shortness of breath and nausea suggest a possible myocardial infarction (MI). A 12-lead EKG is the priority to confirm MI by detecting ST-segment changes or Q waves, enabling rapid diagnosis and intervention to restore coronary blood flow and minimize heart damage. Choice B reason: Administering enteric-coated acetaminophen is inappropriate, as it addresses pain but not the underlying cause of these symptoms, which may indicate an MI. Acetaminophen lacks anti-inflammatory or anti-ischemic properties, and delaying diagnostic measures like an EKG could worsen outcomes in a potential cardiac emergency. Choice C reason: Obtaining an echocardiogram is not the priority in this acute scenario. While it assesses heart structure and function, it is less urgent than a 12-lead EKG, which quickly diagnoses MI by identifying ischemic changes. Echocardiography may follow later to evaluate complications like wall motion abnormalities. Choice D reason: Administering ibuprofen is not appropriate, as it does not address the potential MI indicated by these symptoms. Ibuprofen may relieve pain but lacks specificity for cardiac ischemia and could delay critical diagnostic steps like an EKG, risking further myocardial damage in an acute cardiac event.
