In the pulseless electrical activity algorithm, what is the first step?

• A. Chest Compressions and Oxygen First
• B. Defibrillation
• C. Check Rhythm
• D. Administer Epinephrine

Answer: (A)

Immediate high-quality chest compressions with 100% oxygen are the first action. In pulseless electrical activity, there’s organized electrical activity but no effective heartbeat, so the top priority is to restore perfusion quickly. Starting CPR right away maintains blood flow to the brain and heart while you address reversible causes. Defibrillation isn’t used yet because the rhythm isn’t shockable, and epinephrine and rhythm checks come after initiating CPR and continuing it for cycles.
