A client is admitted with chest pain, and the nurse suspects angina pectoris. Which diagnostic test would the nurse expect to be ordered as an initial assessment?

A) This choice is incorrect because sharp, stabbing chest pain is not the typical presentation of an acute MI. It is more common in conditions like pleuritis or pneumothorax.

B) This choice is incorrect because chest pain relieved by rest and nitroglycerin is more characteristic of stable angina, not an acute MI. Acute MI pain is typically not relieved by these measures.

C) This choice is correct. Sudden, severe chest pain that radiates to the back is a classic presentation of an acute myocardial infarction. The pain is often described as crushing or pressure-like and may be accompanied by other symptoms such as shortness of breath, diaphoresis, and nausea.

D) This choice is incorrect because mild, intermittent chest discomfort during activity is more typical of stable angina, not an acute MI. Acute MI pain is usually more severe, prolonged, and occurs at rest or with minimal exertion.

A) This choice is incorrect because obtaining a detailed health history is important, but administering aspirin is the priority action in a suspected MI. Aspirin helps to prevent further clot formation and reduces the risk of complications during a myocardial infarction.

B) This choice is correct. Administering aspirin as prescribed is the priority action in a suspected MI. Aspirin acts as an antiplatelet agent and can help to prevent the formation of blood clots that could exacerbate the blockage in the coronary artery.

C) This choice is incorrect because while performing a complete physical examination is important, administering aspirin takes precedence in a suspected MI to address the potential clot formation.

D) This choice is incorrect because placing the client in a supine position is not the priority action in a suspected MI. The client's position should be adjusted based on their comfort and ability to breathe effectively.
