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.
