Question 9 • Introduction to Law, Public Safety, Corrections, and Security

Cardiopulmonary resuscitation (CPR)

Answer
A
keeps the brain alive for 20 minutes
B
allows air to enter the lungs
C
preserves brain function
D
is the electrical means for keeping the brain working

Explanation

CPR uses chest compressions, often combined with rescue breaths, to help keep blood and oxygen moving to the brain and other vital organs until normal circulation can be restored. This helps preserve brain function; it does not guarantee that the brain stays alive for a set time. Therefore, the correct choice is “preserves brain function.”
