The nurse is caring for a client with an acute myocardial infarction (AMI). What emergent procedure does the nurse anticipate the physician will order?
Exercise electrocardiography.
Computed tomography (CT) of the chest with contrast.
Echocardiogram.
Percutaneous coronary intervention (PCI).
The Correct Answer is D
Choice A rationale
Exercise electrocardiography, also known as a stress test, is not typically the first-line emergent procedure for a patient with an acute myocardial infarction (AMI). This test is often used to diagnose coronary artery disease, but it is not typically used to treat an AMI5.
Choice B rationale
A computed tomography (CT) scan of the chest with contrast could be used to visualize the heart and surrounding structures, but it is not typically the first-line emergent procedure for a patient with an AMI5.
Choice C rationale
An echocardiogram could be used to visualize the heart’s structure and function, but it is not typically the first-line emergent procedure for a patient with an AMI5.
Choice D rationale
Percutaneous coronary intervention (PCI) is the correct answer. This procedure is often used as an emergent treatment for an AMI. It involves using a catheter to place a small structure called a stent to open up blood vessels in the heart that have been narrowed by plaque buildup.

Correct Answer is D
Explanation
Choice A rationale
Elevating the leg above the level of the heart would not be beneficial in this case. This action would actually reduce blood flow to the leg, which is already compromised due to the arterial occlusion.
Choice B rationale
Exercising the leg would increase the oxygen demand of the tissues in the leg, which could exacerbate the problem. The tissues in the leg are already deprived of oxygen due to the arterial occlusion.
Choice C rationale
Applying a compression stocking to the leg would not be beneficial in this case. This action would further compromise blood flow to the leg, which is already reduced due to the arterial occlusion.
Choice D rationale
Keeping the patient in bed in the supine position is the correct action. This position will decrease the oxygen demand of the tissues in the leg and minimize ischemic damage until circulation can be restored.
Correct Answer is B
Explanation
Choice A rationale
Idiopathic vasospasm, or spontaneous constriction of the blood vessels, can cause myocardial ischemia. However, this is a relatively rare cause compared to atherosclerosis.
Choice B rationale
Atherosclerosis, a condition characterized by the buildup of fatty plaques in the arteries, is the most common cause of myocardial ischemia. These plaques can restrict blood flow to the heart muscle, leading to ischemia.
Choice C rationale
Venous emboli, or blood clots that form in the veins, typically do not cause myocardial ischemia. These clots are more likely to cause problems in the lungs (pulmonary embolism) if they travel through the bloodstream.
Choice D rationale
Arterial emboli from a heart valve can cause myocardial ischemia, but this is less common than atherosclerosis. These emboli, or blood clots, can block blood flow to the heart muscle if they travel through the bloodstream.
