A 7-year-old is in cardiac arrest. Two rescuers are present. What is the correct compression-to-ventilation ratio?
Answer: 15:2
Two-rescuer pediatric CPR uses a 15:2 compression-to-ventilation ratio, unlike the 30:2 for single rescuers or adults.
Which of the following is the most common initial cardiac rhythm found in pediatric cardiac arrest?
Answer: Asystole/PEA
Asystole and PEA are the most common arrest rhythms in children, reflecting hypoxia as the primary etiology.
During CPR for a child with an advanced airway in place, what is the recommended ventilation rate?
Answer: 1 breath every 6 seconds (10/min)
With an advanced airway, deliver asynchronous ventilations at 1 breath every 6 seconds (10 breaths/min) without pausing compressions.
Amiodarone is being considered for a child in refractory VF. What is the correct IV/IO dose?
Answer: 5 mg/kg
Amiodarone 5 mg/kg IV/IO is the PALS dose for shock-refractory VF or pulseless VT.
Which of the following best describes the correct depth of chest compressions in a school-age child (not infant)?
Answer: At least 1.5 inches (about one-third AP chest diameter)
For children, compress at least one-third the anterior-posterior chest diameter, approximately 2 inches (5 cm).
A neonate in the delivery room fails to respond after initial resuscitation steps. What is the oxygen concentration recommended when initiating positive-pressure ventilation?
Answer: 21% oxygen (room air)
For term newborns, resuscitation begins with room air (21% O2); supplemental oxygen is titrated based on SpO2.
What is the maximum single dose of epinephrine (1:10,000) that should be given IV/IO to a child during cardiac arrest?
Answer: 1 mg
The maximum single IV/IO epinephrine dose is 1 mg, regardless of calculated weight-based dose.
