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.
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 C
Explanation
Choice A rationale
This sequence is incorrect because it suggests that blood goes from the lungs to the pulmonary artery, which is not accurate. The pulmonary artery carries deoxygenated blood from the heart to the lungs.
Choice B rationale
This sequence is incorrect because it suggests that blood goes from the pulmonary vein to the lungs, which is not accurate. The pulmonary vein carries oxygenated blood from the lungs to the heart.
Choice C rationale
This sequence correctly describes the direction of blood flow through the heart and lungs. Deoxygenated blood enters the right atrium, goes to the right ventricle, then is sent to the lungs via the pulmonary artery. After picking up oxygen in the lungs, the blood returns to the heart via the pulmonary vein, entering the left atrium, then the left ventricle, from where it is pumped out to the rest of the body.
Choice D rationale
This sequence is incorrect because it suggests that blood goes from the pulmonary vein to the pulmonary artery, which is not accurate. The pulmonary vein carries oxygenated blood from the lungs to the heart, and the pulmonary artery carries deoxygenated blood from the heart to the lungs.
Correct Answer is B
Explanation
Choice A rationale
While it’s important to inquire about an allergy to iodine in a patient who has undergone an angiogram, it’s not typically the priority for assessing and documenting for this patient after the procedure. An allergy to iodine would be more relevant before the procedure, as iodine-based contrast dye is often used during an angiogram.
Choice B rationale
Checking peripheral pulses in the affected leg is typically a priority when caring for a patient who has undergone an angiogram. This is because the procedure involves inserting a catheter into a blood vessel in the leg. Checking the peripheral pulses can help assess for potential complications such as a blood clot or decreased blood flow to the leg.
Choice C rationale
Monitoring for decreased blood pressure is important in a patient who has undergone an angiogram, but it’s not typically the priority for assessing and documenting for this patient after the procedure. While changes in blood pressure can occur after any medical procedure, other assessments such as checking peripheral pulses in the affected leg are typically more directly related to potential complications of an angiogram.
Choice D rationale
Tracking fluid intake is an important part of overall patient care, but it’s not typically the priority for assessing and documenting for a patient who has undergone an angiogram. Other assessments such as checking peripheral pulses in the affected leg are typically more directly related to potential complications of an angiogram.
