CPR is a critical life-saving technique that can make the difference between life and death in emergency situations, such as cardiac arrest.

What is CPR?

CPR stands for Cardiopulmonary Resuscitation. It is a combination of chest compressions and rescue breaths that helps maintain vital blood flow and oxygenation to the brain and other vital organs when the heart stops beating effectively.

a) Call for help

b) Start chest compressions

c) Open the airway

d) Check for breathing
Answer: a) Call for help

2. How deep should chest compressions be for an adult during CPR?

a) 1 inch

b) 2 inches

c) 2.4 inches

d) 3 inches
Answer: b) 2 inches

3. At what rate should chest compressions be delivered during CPR?

a) 60-80 compressions per minute

b) 80-100 compressions per minute

c) 100-120 compressions per minute

d) 120-140 compressions per minute
Answer: c) 100-120 compressions per minute

4. Which of the following is a correct ratio of compressions to breaths for a single rescuer performing CPR on an adult?
