When assessing a male patient in the telemetry unit who is experiencing persistent, crushing chest pain, which symptoms would lead the nurse to suspect a myocardial infarction?

Choice A rationale
A 39-year-old patient experiencing tenderness and swelling in the right calf following a flight may be experiencing deep vein thrombosis (DVT), a condition that can lead to serious complications such as pulmonary embolism if not treated. However, DVT is not immediately life-threatening in most cases.
Choice B rationale
A 58-year-old patient on anticoagulants for atrial fibrillation presenting with black stools is likely experiencing gastrointestinal bleeding, a common side effect of anticoagulant therapy. This can lead to severe blood loss, anemia, and hypovolemic shock, which can be life-threatening if not promptly addressed. Therefore, this patient should be prioritized for assessment.
Choice C rationale
A 67-year-old patient with a gangrenous foot ulcer and a weak pedal pulse likely has peripheral artery disease and an infection that could lead to sepsis if not treated. However, while this condition needs medical attention, it is not as immediately life-threatening as gastrointestinal bleeding.
Choice D rationale
A 50-year-old patient reporting sudden, severe upper back pain could be experiencing a number of conditions, ranging from musculoskeletal strain to aortic dissection. While an aortic dissection is a medical emergency, without additional symptoms such as chest pain, shortness of breath, or loss of consciousness, this patient is not the highest priority.

Choice A rationale
While palpating the liver edge can provide information about liver health and potential fluid accumulation, it is not typically a priority assessment for a patient taking Digoxin (Lanoxin), Furosemide (Lasix), and Captopril.
Choice B rationale
A serum potassium level of 3.0 mEq/L is low (hypokalemia). This is a critical finding because both Digoxin and Furosemide can cause hypokalemia. Hypokalemia increases the risk of digoxin toxicity, which can lead to serious cardiac arrhythmias.
Choice C rationale
While weight gain may indicate worsening heart failure, a gain of 2 pounds over 3 days is not typically considered significant. However, any sudden or unexplained weight gain should be reported to the healthcare provider.
Choice D rationale
Presence of 1+ to 2+ edema in the feet and ankles could indicate worsening heart failure, but it is not as immediately concerning as hypokalemia in a patient taking Digoxin and Furosemide.
