A 49-year-old male presents with chest pain.

An EKG reveals ST elevation, and he is diagnosed with myocardial ischemia. Which of the following interventions would be most beneficial for this patient?

Encourage exercise to increase heart rate.

Administer a diuretic to decrease volume.

Give an antibiotic to decrease infection.

Apply oxygen to increase myocardial oxygen supply.

Answer and Explanation

The Correct Answer is D

Choice A rationale
Encouraging exercise to increase heart rate in a patient with myocardial ischemia could potentially worsen the condition. Exercise increases the demand for oxygen in the heart, which may not be met due to the reduced blood flow in ischemia, potentially leading to further damage.
Choice B rationale
Administering a diuretic to decrease volume is not the most beneficial intervention for a patient with myocardial ischemia. While diuretics can reduce the workload of the heart by decreasing blood volume, they do not directly address the issue of reduced blood flow to the heart muscle that characterizes ischemia.
Choice C rationale
Giving an antibiotic to decrease infection is not relevant in this context. Myocardial ischemia is not caused by an infection, but by a reduction in blood flow to the heart muscle, often due to a blockage in one or more of the coronary arteries.
Choice D rationale
Applying oxygen to increase myocardial oxygen supply is the most beneficial intervention for a patient with myocardial ischemia. Oxygen therapy can help to meet the oxygen demand of the heart muscle when blood flow is reduced, alleviating symptoms and preventing further damage.

Correct Answer is D

Explanation

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.

A. A 39-year-old patient who has right calf tenderness and swelling after a plane ride B. A 58-year-old patient taking anticoagulants for atrial fibrillation who has black stools C. A 67-year-old patient who has a gangrenous foot ulcer with a weak pedal pulse D. A 50-year-old patient who is reporting sudden sharp and severe upper back pain .

Correct Answer is D

Explanation

Choice A rationale
While calf tenderness and swelling after a plane ride could potentially indicate a deep vein thrombosis, this condition is not immediately life-threatening in most cases. The patient would need evaluation and treatment, but other patients might have more urgent needs14.
Choice B rationale
A patient taking anticoagulants for atrial fibrillation who has black stools could potentially have gastrointestinal bleeding, which would need evaluation. However, this condition might not be immediately life-threatening, and other patients might have more urgent needs14.
Choice C rationale
A patient with a gangrenous foot ulcer and a weak pedal pulse would need evaluation and treatment. However, this condition might not be immediately life-threatening, and other patients might have more urgent needs14.
Choice D rationale
A patient reporting sudden sharp and severe upper back pain could potentially have an aortic dissection, which is a life-threatening condition that requires immediate evaluation and treatment. Therefore, this patient should be assessed first14.
