Final answer:
The correct treatment plan for defibrillation in pediatric patients aged 24 hours to under 8 years old is to start with 2 Joules/kg and escalate as needed.
Step-by-step explanation:
The treatment plan for manual defibrillation for a patient who is between 24 hours old to under 8 years old is to start with 2 Joules/kg escalating. Therefore, the correct answer is b. Start with 2 Joules/kg escalating. If the initial defibrillation attempt is not successful, the energy dose may be increased for subsequent attempts, following the established pediatric advanced life support (PALS) guidelines and protocols. It is important to adhere to proper protocols when performing defibrillation to ensure safety and effectiveness.
