During pediatric CPR, what is the recommended compression-to-ventilation ratio for a single rescuer?
Answer: 30:2
A single rescuer uses a 30:2 compression-to-ventilation ratio for all pediatric patients.
A 4-year-old is in ventricular fibrillation. What is the correct initial defibrillation dose?
Answer: 2 J/kg
The initial defibrillation dose for pediatric patients is 2 J/kg; subsequent doses are 4 J/kg.
Which rhythm would you NOT attempt to defibrillate in a pediatric cardiac arrest?
Answer: Asystole
Asystole is a non-shockable rhythm; defibrillation is only indicated for VF and pulseless VT.
After delivering an initial 2 J/kg shock in a child with VF, what is the recommended second defibrillation dose?
Answer: 4 J/kg
Subsequent defibrillation doses are 4 J/kg or higher (up to 10 J/kg or adult max) if the initial dose fails.
During pediatric cardiac arrest resuscitation, how soon after defibrillation should CPR be resumed?
Answer: Immediately after shock delivery
CPR should be resumed immediately after shock delivery without pausing to check the rhythm or pulse.
A child is in PEA cardiac arrest. Which of the following is a reversible H cause to investigate?
Answer: All of the above
All three are reversible H causes (Hs and Ts) that should be identified and corrected during PEA arrest.
What is the recommended epinephrine dose for a pediatric patient in cardiac arrest?
Answer: 0.01 mg/kg IV/IO (1:10,000)
Epinephrine 0.01 mg/kg (1:10,000 solution) IV/IO is the standard PALS cardiac arrest dose, repeated every 3-5 minutes.
