Explanation

Targets the heart for effective compressions.

#12

What is the purpose of an AED (Automated External Defibrillator) in BLS?

To analyze heart rhythm and deliver a shock if necessary
Explanation

Restores normal heart rhythm in case of cardiac arrest.

#13

What is the primary purpose of rescue breaths in BLS?

To provide oxygen to the lungs
Explanation

Ensures oxygenation of the victim's body.

#14

What should you do before using an AED (Automated External Defibrillator) on a victim?

Check for responsiveness and breathing
Explanation

Confirms the need for defibrillation and readiness for treatment.

#15

What is the recommended sequence for CPR steps?

Explanation

Follows the correct order for maximizing survival.

#16

When should you reassess the victim during CPR?

Every 2 minutes
Explanation

Ensures ongoing assessment and adaptation of treatment.

#17

What should you do if the victim is not breathing but has a pulse?

Administer rescue breaths
Explanation

Provides necessary oxygenation for the victim.

#18

What is the recommended hand placement for chest compressions in pediatric CPR?

Lower half of the sternum
Explanation

Targets the pediatric heart effectively for compression.

#19

What should you do if the victim is unconscious but breathing normally?

Place the victim in the recovery position
Explanation

Maintains open airway and prevents aspiration.

#20

What is the purpose of the recovery position in first aid?

To maintain an open airway
Explanation

#21

During BLS, what should you do if the victim starts to vomit?

Explanation

Prevents airway obstruction and ensures continued CPR.

#22

What is the recommended ratio of chest compressions to rescue breaths in infant CPR?

15:2
Explanation

Optimizes circulation and oxygenation for infants.

#23

What is the primary goal of Basic Life Support (BLS) procedures?

To maintain blood circulation and oxygenation
Explanation

Preserves vital functions until further medical help arrives.

When emergency medical services (EMS) arrive
Explanation

Transitions care to advanced medical providers.

#25

Which of the following is a potential complication of chest compressions during CPR?
