A.    Perform abdominal thrusts, then clean out the mouth with a finger.
B.    Deliver rescue breaths using a mask.
C.    Perform the tongue lift / finger sweep technique.
D.    Perform the head tilt / chin lift technique.

2. What mistake is most likely to cause gastric inflation during use of a bag-mask?

B.    Too much air is given in rescue breaths; the chest is visibly rising.

3. Why is complete chest recoil good for CPR?

A.    It reduces rescuer exhaustion.
B.    It reduces the chance of fractured ribs.
C.    It increases the chest compression rate.
D.    It gives the heart a chance to fill with blood between compressions.

4. A person starts to choke, and it looks serious. The person stays responsive. What is the best response?

A.    Immediately begin CPR.
B.    Immediately deliver abdominal thrusts.
C.    Deliver 5 back slaps, and then 2 rescue breaths.
D.    Deliver 2 breaths and reposition the airway after every breath.
