To keep the patient calm
Where is the heart located in the body?
To the far right of the chest cavity
Directly behind the stomach
Behind the sternum, slightly left of center
Above the collarbone
Which chamber of the heart is most responsible for pumping blood to the body?
Right atrium
Right ventricle
Left atrium
Left ventricle
During chest compressions, the heart is compressed between the sternum and which structure?
Ribs
Diaphragm
Spine

At least 2 inches (5 cm)
3 inches (7.5 cm)
4 inches (10 cm)
What is the ideal rate for chest compressions?
60–80 compressions per minute
80–100 compressions per minute
100–120 compressions per minute
120–150 compressions per minute
Which part of the sternum should be avoided during compressions?
Manubrium
Body
Xiphoid process
Costal cartilage
Which bones protect the heart and lungs and flex during compressions?
Femurs
Vertebrae
Clavicles
Ribs
Why is full chest recoil important during compressions?
It increases blood pressure
It helps the rescuer breathe
It allows the heart to refill with blood
It prevents the ribs from breaking

Manubrium
Clavicle
Lower half of the sternum
Rib cage
What is a common injury that can occur from proper chest compressions?
Broken leg
Dislocated shoulder
Broken ribs
Sprained wrist
Why should rescuers switch every 2 minutes during CPR?
To check for breathing
To reposition the patient
To prevent rescuer fatigue and maintain compression quality
To increase compression speed
