CPR & BLS BASIC LIFE SUPPORT EXAM
Questions and Answers
1. All cardiac arrests situations are shockable by an AED
ANS False
2. What is accomplished by CPR?
ANS It circulates blood until the heart is restored to good health
3. What is cardiac arrest?
ANS When the heart stops effectively pumping blood
4. How much blood is pumped during an effective chest compression
compared to a normal heartbeat?
ANS 30%
5. How does defibrillation work?
ANS It stuns the heart to stop ventricular fibrillation.
6. When is it appropriate to place a victim in the recovery position?
ANS When ROSC has
been restored
7. What is the rule of thumb for how long you should check for
1/
6
, responsiveness?-
ANS Check for between 5 and 10 seconds
8. You are a lone rescuer who is getting tired from performing chest
compres- sions. What action should be taken when more rescuers arrive?
ANS Assign tasks to other rescuers and rotate compressors to avoid fatigue
9. In adult CPR, when should the emergency response system be
activated?
ANS Be- fore administering CPR
10. During CPR, what is the ratio of chest compressions to rescue
breaths in adults?
ANS 30 compressions to 2 breaths
11. When there are two rescuers, what should the second rescuer
do if their partner is delivering a shock with a defibrillator?
ANS Stay clear when told
12. Why is allowing the complete chest recoil important when
performing CPR?-
ANS So the blood can re-fill the heart's chambers between compressions
