2-2.5 inches.

3-4 inches.

1-2 inches.

More than 4 inches.

2 / 30

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

3 / 30

3. The ratio of chest compressions to rescue breaths for a single rescuer providing Adult CPR is:

2:1

Continuous breaths only

15:1

30:2

4 / 30

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

Place the adult in the recovery position.

Chest compressions only.

High-quality CPR (compressions and rescue breaths).

Rescue breathing only.

5 / 30

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

Allow passive chest rise for each breath.

Pinch the nose closed and seal your mouth over the adult's mouth.

All of the above.

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

6 / 30

6. When performing CPR on a very obese adult, it’s crucial to:

Ensure adequate chest recoil between compressions.

Use a different hand position for chest compressions.

Perform CPR with one hand only due to limited space.

Perform shallower chest compressions (less than 2 inches).

7 / 30

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

8 / 30

8. CPR can be performed on an adult lying on their back on any firm surface.

False

True

9 / 30

9. The recommended rate for chest compressions in Adult CPR is:

20-30 compressions per second.

100-120 compressions per minute.

10 compressions per minute.

60-80 compressions per minute.

10 / 30

10. The correct hand placement for chest compressions in an adult is on the:

Back, between the shoulder blades.

Lower abdomen (belly button).

Upper chest (breastbone).

Lower ribs (below the breastbone).

11 / 30

11. When checking for a pulse in an adult during BLS, the most appropriate location is:

Groin (femoral artery)

Ankle (dorsalis pedis artery)

Neck (carotid artery)

Wrist (radial artery)

12 / 30

12. If a single rescuer providing Adult CPR encounters a foreign object obstructing the airway, the first course of action should be:

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

Delay interventions and wait for EMS.

Perform a finger sweep maneuver to dislodge the object.

Perform the Heimlich maneuver (abdominal thrusts).

13 / 30

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

14 / 30

14. 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.

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

Only medical professionals should attempt CPR on adults.

Early intervention and bystander CPR significantly improve survival chances.

15 / 30

15. Choking in an adult can sometimes be mistaken for cardiac arrest. One key difference is:

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.

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

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

16 / 30

16. When using an AED on an adult, it’s important to ensure no jewelry or metal objects are touching their skin where the AED pads will be placed.

True

False

17 / 30

17. 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:

Delay CPR until emergency medical services arrive.

Only perform rescue breaths and avoid chest compressions.

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

Perform CPR as usual without attempting spinal stabilization.

18 / 30

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

Ensuring adequate ventilation with rescue breaths.

Minimizing interruptions in chest compressions.

Maintaining a calm and focused demeanor.

Checking for a pulse after every two minutes.

19 / 30

19. During chest compressions, it’s crucial to:

Perform quick, shallow compressions.

Keep your arms straight with elbows locked.

Allow the chest to fully rise between compressions.

Lean back with your entire body weight on each compression.

20 / 30

20. The recommended rate for delivering rescue breaths in Adult CPR with a single rescuer is breaths per minute.

21 / 30

21. Adult BLS guidelines recommend checking for a pulse for a full minute before initiating CPR.

True

False

22 / 30

22. You approach an unresponsive adult. The initial step in Adult BLS assessment is to:

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

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

Call for emergency medical services (EMS) immediately.

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

23 / 30

23. When checking for breathing in an adult, signs of absent breathing include:

Gasping breaths.

Slow and shallow respirations.

Chest rising and falling with each breath.

No audible breath sounds.

24 / 30

24. CPR should be avoided on an adult who is gasping or shows any signs of agonal respirations (agonal breathing).

False

True

25 / 30

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

The adult regains consciousness.

A return of a pulse.

Return of Spontaneous Circulation (ROSC)

All of the above.

Stop CPR and step away from the adult.

Deliver several rescue breaths before attaching the AED pads.
