Which of the following statements about rhythm checks and defibrillation during pediatric CPR is correct?

• A. Rhythm checks occur every 2 minutes and after defibrillation
• B. Rhythm checks are performed only at the start
• C. Rhythm checks are performed every 5 minutes
• D. Rhythm checks are not required

Answer: (A)

In pediatric CPR, rhythm checks are timed to balance ongoing chest compressions with necessary rhythm assessment. Checking the rhythm every two minutes keeps you aligned with the CPR cycle, allowing timely recognition of return of spontaneous circulation or the need for another defibrillation shock. After delivering a defibrillation shock, you re-check the rhythm to decide if another shock is indicated. This approach minimizes interruptions to compressions while ensuring treatment decisions are based on current rhythm status. Rhythm checks only at the start, or every five minutes, or not required would miss important changes and delay appropriate defibrillation or escalation of care.
