#3
Which of the following is NOT a component of the chain of survival for cardiac arrest?
Early antibiotic administration
ExplanationEarly antibiotic administration is not part of the chain of survival for cardiac arrest.
#4
What is the recommended depth of chest compressions during CPR for infants?
1/2 inch
ExplanationChest compressions of 1/2 inch ensure effective circulation in infants during CPR.
#5
What is the most common cause of cardiac arrest in adults?
Heart attack
ExplanationHeart attack is the leading cause of cardiac arrest in adults.
#6
What is the recommended compression rate during CPR for adults?
120 compressions per minute
Explanation120 compressions per minute optimize blood circulation during CPR for adults.
#7
Which of the following is a shockable rhythm in cardiac arrest?
Ventricular fibrillation
ExplanationVentricular fibrillation is a rhythm that can be corrected with defibrillation.
#8
What is the recommended compression-to-ventilation ratio for CPR in adults?
30:2
ExplanationThe ratio of 30 compressions to 2 ventilations optimizes CPR effectiveness in adults.

ExplanationChest compressions of 2 inches ensure effective circulation in adults during CPR.
#12
During CPR, what is the correct hand placement for performing chest compressions on an adult?
Upper third of the sternum
ExplanationHand placement on the upper third of the sternum ensures effective compressions.
#13
Which medication is commonly administered during advanced life support for cardiac arrest to improve the chances of survival?
Epinephrine
ExplanationEpinephrine administration enhances chances of survival during cardiac arrest.
#14
What is the first action to take if you witness a person collapse suddenly and become unresponsive?
Shout for help
ExplanationImmediately calling for help is crucial upon witnessing sudden collapse and unresponsiveness.
