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?

Choice A rationale
Pulsus paradoxus, an exaggerated decrease in systolic blood pressure during inspiration, can be a sign of several conditions, including pericardial tamponade, constrictive pericarditis, and restrictive cardiomyopathy.
Choice B rationale
Exudate, a fluid with a high protein content that leaks out of blood vessels due to inflammation, is not typically associated with the symptoms described.
Choice C rationale
An aneurysm, a bulge or ballooning in a blood vessel, could potentially cause the symptoms described, but it is not the most concerning finding given the symptoms of edema, hepatomegaly, and muffled heart sounds.
Choice D rationale
Tamponade, a serious condition in which fluid or blood fills the pericardial sac, compressing the heart and preventing it from pumping effectively, could cause the symptoms described and would be the most concerning finding.

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.
