70% to pass

How deeply should the sternum be depressed when applying chest compressions on an adult victim during CPR?

A 1-1/2 to 2 inches
B 1/2 inch or less
C 1 to 1-1/2 inches
D 1/2 to 1 inch
AI Explanation

The correct answer is A) 1-1/2 to 2 inches. This depth of chest compression is the current recommendation from the American Heart Association for adult CPR. Compressing the sternum 1-1/2 to 2 inches allows for adequate circulation and blood flow during CPR. Anything less than 1-1/2 inches (options B and C) would not provide sufficient force to effectively pump the heart and circulate blood. Compressing more than 2 inches (not an option provided) could risk injury to the victim.
