Nursing priorities in suspected MI include which of the following?

• A. Delay treatment until laboratory results confirm MI.
• B. ECG; Assess pain; Oxygen if needed; Prepare reperfusion.
• C. Immediate antibiotics.
• D. Keep patient NPO and observe.

Answer: (B)

In suspected myocardial infarction, the priority is rapid assessment and initiation of reperfusion to limit heart muscle damage. The most important step is obtaining an ECG right away to detect ischemia or infarction and guide urgent treatment. At the same time, assess the patient’s pain and overall stability, since ongoing pain and hemodynamic compromise signal the need for immediate intervention. Oxygen should be given only if the patient is showing hypoxemia or respiratory distress, because unnecessary oxygen can have drawbacks and isn’t beneficial for everyone. Prepare reperfusion promptly, whether through percutaneous coronary intervention or thrombolysis, following the established protocol so blood flow is restored as quickly as possible. Delaying treatment for lab confirmation is inappropriate because troponin levels may be normal early on and don’t change the need for urgent action. Antibiotics have no role in the acute MI management, and simply keeping the patient NPO and observing does not address the urgent need to restore perfusion.
