In the office protocol for suspected myocardial infarction, which action should occur second after turning off nitrous oxide and increasing oxygen?

• A. Call 911
• B. Elevate the patient’s legs
• C. Administer sublingual nitroglycerin
• D. Recline the patient

Answer: (B)

In suspected myocardial infarction, the immediate goal after stopping nitrous oxide and giving oxygen is to support circulation quickly. Elevating the legs helps by increasing venous return to the heart ( preload ), which helps maintain blood pressure and improve perfusion to vital organs while emergency care is arranged. This simple, rapid maneuver can stabilize the patient without risking additional complications, making it the best next step. Reclining the patient or administering nitroglycerin without regard to the patient’s condition and prescription status can be less reliable or contraindicated, and while calling for emergency help is essential, the leg-elevation step specifically addresses rapidly optimizing hemodynamics right after oxygenation.
