What is the priority assessment for a suspected myocardial infarction (MI)?

• A. Cardiac monitoring
• B. Blood glucose measurement
• C. Respiratory rate assessment
• D. Visual acuity

Answer: (D)

In a suspected myocardial infarction, the most urgent concern is the heart’s electrical activity and rhythm. Continuous cardiac monitoring with an ECG lets you detect life‑threatening arrhythmias (like ventricular fibrillation or VT) and identify ischemic changes quickly, which is critical for initiating time‑sensitive treatments such as reperfusion therapy. Other assessments, like measuring blood glucose or checking respiratory status, are important parts of the overall evaluation but do not address the immediate risk to the heart in the way continuous rhythm monitoring does. Visual acuity has no direct relevance to an acute MI assessment.
