    1. If you do not believe there’s a spinal injury, what’s the best way to open a patient’s airway when they are unresponsive?

    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?

    A.    There isn’t a tight seal between the mask and the patient’s face.
    B.    Too much air is given in rescue breaths; the chest is visibly rising.
    C.    The rescuer is delivering breaths too quickly or too forcefully.
    D.    Every breath lasts longer than one second.

    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.

    5. How deep should chest compressions go when delivering CPR to a child?

    A.    At least one quarter of the chest’s depth (approximately 1.5 inches / 4 cm)
    B.    At least one third of the chest’s depth (approximately 2 inches / 5 cm)
    C.    At least two thirds of the chest’s depth (approximately 4 inches / 10 cm)
    D.    At least three fourths of the chest’s depth (approximately 4.5 inches / 12 cm)

    6. When using an AED on a child under 8 years of age, what size should the pads be?

    A.    You can use infant pads if there are no pediatric pads at hand.
    B.    Cut adult pads in half if there are no pediatric pads at hand.
    C.    Use a single adult pad.

    B.    Perform CPR.
    C.    Activate emergency response.
    D.    Begin slapping the victim’s back.

    A.    Perform rescue breaths without chest compressions.
    B.    Perform chest compressions without rescue breaths.
    C.    Deliver both chest compressions and rescue breaths.
    D.    Attach the AED pads to the child’s chest and read the analysis.

    9. What is the compression-to-ventilation ratio for adult CPR involving 2 rescuers?

    A.    5 to 1
    B.    20 to 2
    C.    15 to 2
    D.    30 to 2

    10. What is the compression-to-ventilation ratio for adult CPR involving a single rescuer?

    A.    15 to 2
    B.    20 to 2
    C.    30 to 2
    D.    5 to 1
