Which statement correctly describes the energy for first and subsequent shocks in pediatric defibrillation?

• A. First shock 4 J/kg; subsequent 2 J/kg
• B. First shock 8 J/kg; subsequent 4 J/kg
• C. First shock 2 J/kg; subsequent 4 J/kg
• D. First shock 1 J/kg; subsequent 3 J/kg

Answer: (C)

In pediatric defibrillation, the energy is tailored to the child’s weight and is delivered in two stages to balance effectiveness with safety. The recommended pattern is to give a first shock at 2 joules per kilogram. If the first shock does not terminate the rhythm, subsequent shocks are delivered at 4 joules per kilogram. This escalation helps ensure a higher chance of successful defibrillation while minimizing potential myocardial injury from too-high energy. So, the correct approach is first shock at 2 J/kg, followed by 4 J/kg for later shocks. Higher starting energies or lower subsequent energies are not aligned with standard pediatric guidelines, and using 3 J/kg for later shocks isn’t the supported escalation method.
