- (B) Check for a pulse
- (C) Provide ventilations and operate the AED
- (D) Call for help
View Answer Answer: (C) Explanation: The second rescuer provides ventilations and operates the AED while the first rescuer performs chest compressions.
How often should rescuers switch roles during two-rescuer CPR for children?
- (A) Every 1 minute
- (B) Every 2 minutes
- (C) Every 5 minutes
- (D) Every 10 minutes
View Answer Answer: (B) Explanation: Rescuers should switch roles every 2 minutes to maintain high-quality compressions.
Child Ventilation
What is the proper technique for ventilating a child with a bag-mask device?
- (A) Deliver breaths quickly to inflate the lungs
- (B) Squeeze the bag over one second until the chest rises
- (C) Deliver breaths every 10 seconds
- (D) Squeeze the bag as hard as possible
View Answer Answer: (B) Explanation: Squeeze the bag over one second until the chest rises to ensure proper ventilation without overinflation.
What should you avoid when providing ventilations to a child?
- (A) Giving breaths too quickly
- (B) Using a bag-mask device
- (C) Checking for chest rise
- (D) Using the head-tilt/chin-lift maneuver
View Answer Answer: (A) Explanation: Avoid giving breaths too quickly as this may result in distention of the stomach and potential aspiration.
Self-Assessment for Child BLS
Why is early intervention important in pediatric cardiac arrest?
- (A) Children have stronger hearts
- (B) Pediatric cardiac arrest is often preceded by respiratory issues
- (C) Children recover faster
- (D) Pediatric AEDs are more effective
View Answer Answer: (B) Explanation: Pediatric cardiac arrest is often preceded by respiratory issues, so early intervention can prevent cardiac arrest.
What is the Pediatric Chain of Survival?

- (B) Early recognition, early CPR, rapid activation of EMS, advanced life support, post-cardiac arrest care
- (C) Early recognition, early defibrillation, early advanced care, rapid transport
- (D) Early recognition, rapid EMS activation, advanced life support, early CPR
View Answer Answer: (B) Explanation: The Pediatric Chain of Survival includes early recognition, early CPR, rapid activation of EMS, advanced life support, and post-cardiac arrest care.
How should you open the airway of a child if a neck injury is not suspected?
- (A) Jaw-thrust maneuver
- (B) Head-tilt/chin-lift maneuver
- (C) Abdominal thrusts
- (D) Back blows
View Answer Answer: (B) Explanation: Use the head-tilt/chin-lift maneuver to open the airway if a neck injury is not suspected.
