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 D
Explanation
The correct answer is Choice D.
Choice A rationale: Allergies to shellfish may indicate iodine allergy, relevant for procedures using iodine-based contrast, like PCI. The client’s shellfish allergy must be reported to the PHCP as a precautionary measure to prevent any allergic reaction.
Choice B rationale: Warm sensations during PCI are a common side effect of the contrast dye used in the procedure. This statement does not indicate an immediate concern requiring PHCP notification as it is a standard patient experience.
Choice C rationale: Anxiety in closed spaces, known as claustrophobia, may affect the client's comfort during PCI but can be managed with sedatives. The PHCP should be aware but it’s not as urgent as taking contraindicated medications.
Choice D rationale: Metformin can lead to lactic acidosis, especially when iodine contrast dye is used during PCI. This condition is serious and may result in adverse interactions. The PHCP must be notified immediately.
Correct Answer is A
Explanation
Choice A rationale
A 59-year-old patient with unstable angina who has just returned from a percutaneous coronary intervention (PCI) should be prioritized for assessment. PCI is a procedure to open blocked or narrowed coronary arteries and can lead to complications such as re-occlusion of the artery or bleeding from the catheter insertion site. Furthermore, unstable angina is a condition that can progress to myocardial infarction if not managed effectively.
Choice B rationale
A 56-year-old patient with variant angina due to receive nifedipine (Procardia) requires monitoring, but is not the highest priority. Variant angina is a form of angina that occurs at rest, often with severe pain, but it is usually well-controlled with medications like nifedipine.
Choice C rationale
A 65-year-old patient who had a myocardial infarction (MI) 4 days ago and is anxious about discharge planned for today is a lower priority for assessment. While it’s important to address the patient’s anxiety and provide education about post-discharge care, this patient is not in immediate danger.
Choice D rationale
A 39-year-old patient with pericarditis complaining of sharp, stabbing chest pain requires assessment, but is not the highest priority. Pericarditis is inflammation of the pericardium, the sac-like covering of the heart, and while it can cause severe pain, it is not typically life- threatening.
