A 67-year-old man is found unresponsive, not breathing, and without a pulse. You and a second rescu
begin performing high-quality CPR.
1. When should rescuers switch positions during CPR?
A. Never switch rescuers
B. When placing the AED pads
C. About every 2 minutes
D. At 5-minute intervals
2. You notice the person giving chest compressions is not allowing for complete chest recoil. What is
your next course of action?
A. Stand back and await direction from the second rescuer
B. Tell the rescuer the compressions are wrong
C. Immediately take over chest compressions
D. Tell the compressor you notice decreased chest recoil
3. "The team functions smoothly when all team members know their positions, functions, and tasks
during a resuscitation attempt." Match this statement with the most appropriate element of team
dynamics listed.
A. Clear roles and responsibilities
B. Knowing your limitations
C. Constructive intervention
D. Mutual respect
4. Early defibrillation is a link in the adult Chain of Survival. Why is this important to survival?
A. It prevents respiratory arrest.
B. It prevents cardiac arrest.
C. It provides normal respiration.
D. It eliminates the abnormal heart rhythm.
5. What special circumstance should a rescuer consider when using an AED?
A. They should never use an AED on someone with an implanted pacemaker.
B. On a hairy chest, the pads may not stick and may fail to deliver a shock.
C. AEDs can only be used while a person is submerged in water.
D. They should never remove a transdermal medication patch before applying AED pads.

Sure, I'd be happy to help with that! 1. Rescuers should switch positions during CPR about every 2 minutes. This helps prevent rescuer fatigue and ensures that high-quality CPR is consistently maintained throughout the resuscitation attempt. 2. If you notice that the person giving chest compressions is not allowing for complete chest recoil, your next course of action should be to immediately take over chest compressions. Proper chest recoil is essential for effective CPR and optimal blood flow to the heart and brain. 3. The statement "The team functions smoothly when all team members know their positions, functions, and tasks during a resuscitation attempt" matches with the element of team dynamics known as clear roles and responsibilities. Having clear roles helps ensure that each team member knows what is expected of them and can perform their tasks efficiently during a resuscitation effort. 4. Early defibrillation is a critical link in the adult Chain of Survival because it eliminates the abnormal heart rhythm by delivering a shock to the heart. This is important for restoring a normal heart rhythm and increasing the chance of survival in cases of sudden cardiac arrest. 5. When using an AED, a rescuer should consider the special circumstance that on a hairy chest, the pads may not stick well and could fail to deliver a shock effectively. To address this, the rescuer may need to quickly shave the chest or use an AED with pads designed for use on hairy surfaces. This ensures that the electrical shock can be delivered properly to the heart in case of a cardiac emergency.
