1. Which of the following is the correct sequence of actions

for performing high-quality CPR on an adult victim of

cardiac arrest?

A) Check for responsiveness, activate emergency response

system, get AED, open airway, give 2 breaths, start chest

compressions

B) Check for responsiveness, open airway, give 2 breaths,

start chest compressions, activate emergency response

system, get AED

C) Check for responsiveness, activate emergency response

system, get AED, start chest compressions, open airway,

give 2 breaths

D) Check for responsiveness, start chest compressions,

activate emergency response system, get AED, open

airway, give 2 breaths

Answer: D. The correct sequence of actions for performing

high-quality CPR on an adult victim of cardiac arrest is

CAB: Compressions-Airway-Breathing. The first step is to

check for responsiveness and pulse. If the victim is

unresponsive and has no pulse, start chest compressions

immediately at a rate of 100-120 per minute and a depth of

at least 2 inches. The second step is to activate the

emergency response system and get an AED as soon as

possible. The third step is to open the airway and give 2

breaths with a barrier device after every 30 compressions.

The ratio of compressions to breaths is 30:2 for single

rescuers and 15:2 for two rescuers.
