If the rhythm is nonshockable, what is the recommended action?

• A. Wait for ALS
• B. Deliver a second shock
• C. Pause CPR for 1 minute
• D. Immediately resume CPR for about 2 minutes

Answer: (D)

When the rhythm is nonshockable, the priority is to keep blood flowing to vital organs rather than delivering a shock. Defibrillation targets shockable rhythms and won’t help in asystole or pulseless electrical activity, so you resume high-quality CPR immediately to maintain perfusion. Continue chest compressions right away, with minimal interruptions, for about 2 minutes before rechecking the rhythm and pulse and considering advanced interventions. This approach maximizes the chance of ROSC by keeping blood flow going while awaiting further help. Pausing CPR or waiting for ALS would deprive the brain and heart of oxygen-rich blood, and delivering a shock offers no benefit in a nonshockable rhythm.
