CPR and Cardiac Arrest Concepts

What is the primary function of arteries in the human body?

• Carry deoxygenated blood back to the heart.

• Carry oxygen and nutrients away from the heart to the body.

• Filter waste products from the blood.

• Regulate body temperature.

What occurs during sudden cardiac arrest?

• The heart beats too fast.

• The heart stops beating effectively, and blood flow stops.

• The brain stops functioning.

• The lungs stop working.

Why is it crucial to begin CPR immediately for a person experiencing sudden cardiac arrest?

• It helps the person regain consciousness instantly.

• It is the person's only chance of survival.

• It prevents all vital organs from dying.

• It ensures medical help arrives faster.

How soon can brain damage start after sudden cardiac arrest if no intervention is provided?

• Within 1 minute.

• Within 4 minutes.

• Within 10 minutes.

• After 15 minutes.

What are the two main objectives achieved by performing CPR?

• Moving blood to the lungs and cooling the body.

• Moving oxygenated blood to the brain and keeping blood/oxygen moving to the heart muscle.

• Restarting breathing and checking for a pulse.

• Providing nutrients to the body and regulating blood pressure.

What is the minimum recommended depth for chest compressions during CPR?

• At least 1 inch.

• At least 2 inches.

• At least 3 inches.

• At least 4 inches.

What is the recommended rate for chest compressions per minute during CPR?

• 60-80 compressions per minute.

• 80-100 compressions per minute.

• 100-120 compressions per minute.

• 120-140 compressions per minute.

Why should interruptions in chest compressions be minimized during CPR?

• To prevent the patient from waking up.

• To avoid tiring out the rescuer.

• To ensure continuous blood flow to the brain.

• To allow the heart to rest.

What is the consequence of not performing chest compressions deep enough during CPR?

• The heart will not refill with blood.

• The patient will feel more pain.

• Blood will not reach the brain effectively.

• The compressions will be too fast.

What is the main purpose of delivering chest compressions during CPR?

• To stimulate the patient's breathing.

• To keep oxygenated blood moving within the heart and up to the brain.

• To prepare the patient for an AED shock.

• To check for signs of circulation.
