What is listed as the first step in managing cardiac arrest?

• A. CPR
• B. Defibrillate if in VT or VF
• C. Epinephrine first
• D. Observe and wait

Answer: (A)

In cardiac arrest, preserving blood flow to the brain and heart right away is crucial, so the best first move is to start high-quality chest compressions immediately. This CPR action maintains coronary and cerebral perfusion and buys critical time while help arrives and a defibrillator is prepared. Defibrillation is vital for shockable rhythms (like ventricular fibrillation or pulseless VT), but it should occur as soon as the device is ready without delaying CPR. Epinephrine is a later consideration in ACLS, and simply observing and waiting offers no lifeline in this situation.
