What is the recommended action after delivering a shock if the rhythm remains VF/pVT?

• A. Resume CPR immediately and continue for about 2 minutes before rechecking rhythm
• B. Stop CPR and observe
• C. Immediate reanalysis and check for pulse
• D. Administer calcium chloride

Answer: (A)

After delivering a shock for a shockable rhythm, if VF or pulseless VT persists, the priority is to restore perfusion while preparing for the next shock. The best action is to immediately resume high-quality CPR and continue for about two minutes before rechecking the rhythm. This keeps blood flowing to the heart and brain during the pause between shocks, which improves the chances of return of spontaneous circulation when the next defibrillation is attempted. Stopping CPR to observe or immediately reanalyzing during the CPR interval would reduce perfusion and worsen outcomes. After completing the CPR interval, reanalyze the rhythm and check for a pulse; if the rhythm remains shockable and there is no ROSC, deliver another shock and continue the cycle. Calcium chloride isn’t a routine post-shock treatment in this scenario unless there are specific indications like hyperkalemia or certain overdoses.
