Perform shallower chest compressions (less than 2 inches).

Use a different hand position for chest compressions.

Perform CPR with one hand only due to limited space.

8 / 30

False

True

9 / 30

9. While performing CPR on an adult, it’s important to avoid:

Ensuring adequate ventilation with rescue breaths.

Checking for a pulse after every two minutes.

Minimizing interruptions in chest compressions.

Maintaining a calm and focused demeanor.

10 / 30

10. When providing chest compressions on an adult with a suspected chest injury, it’s recommended to:

Avoid chest compressions and focus solely on rescue breaths.

Perform slanted compressions, avoiding the injured area.

Locate and perform compressions on the lower tip of the breastbone

Perform standard compressions on the center of the breastbone.

11 / 30

Call for emergency medical services (EMS) immediately.

Check for pulse and breathing for no more than 10 seconds.

Open the airway and check for breathing signs (look, listen, feel) for 10 seconds.

Check for a pulse at the carotid artery for a full minute.

12 / 30

12. The maneuver is used to open the airway of an unresponsive adult.

13 / 30

13. CPR can be a lifesaving intervention, but it’s crucial to remember that:

It's a guaranteed way to revive an adult in cardiac arrest.

Early intervention and bystander CPR significantly improve survival chances.

It's more important to wait for EMS than to attempt CPR yourself.

Only medical professionals should attempt CPR on adults.

14 / 30

14. The ideal depth for each chest compression in an adult is inches.

15 / 30

15. If you determine the adult is unresponsive and not breathing, you should initiate:

Chest compressions only.

Place the adult in the recovery position.

Rescue breathing only.

High-quality CPR (compressions and rescue breaths).

16 / 30

16. CPR cycles for a single rescuer providing Adult CPR consist of chest compressions followed by rescue breaths.

Perform a finger sweep maneuver to dislodge the object.

Deliver several rescue breaths and attempt to cough up the object.

Perform the Heimlich maneuver (abdominal thrusts).

Delay interventions and wait for EMS.

20 / 30

20. It’s important to be aware of your surroundings when performing CPR on an adult. If you suspect a spinal injury, it’s recommended to:

Perform CPR as usual without attempting spinal stabilization.

Only perform rescue breaths and avoid chest compressions.

Delay CPR until emergency medical services arrive.

Minimize movement of the head and neck and attempt to stabilize the spine if possible before initiating CPR.

21 / 30

21. The depth for each chest compression in an adult should be:

More than 4 inches.

3-4 inches.

2-2.5 inches.

1-2 inches.

22 / 30

22. Signs of successful chest compressions during Adult CPR may include:

All of the above.

A return of a pulse.

The adult regains consciousness.

CPR is the primary intervention for choking, while it's not for cardiac arrest.

Presence of a pulse in choking but not in cardiac arrest.

Choking victims will be unresponsive, while those in cardiac arrest may be conscious.

Choking victims will have agonal breathing, while those in cardiac arrest will not.

25 / 30

25. The appropriate technique for delivering rescue breaths in an adult is:

Deliver a slow, deep breath into the adult's mouth.

Allow passive chest rise for each breath.

All of the above.
