10CPR should be initiated when:
- Arigor mortis is obvious.

11CPR will NOT be effective if the patient is:
- Ahorizontal.
- Bon a firm surface.
- CProne

12During two-rescuer CPR, the compressor and ventilator switch positions. While rescuer one is finishing his or her cycle of 30 compressions, rescuer two should:
- Aassess for a carotid pulse for 15 seconds.

- Cgive two breaths and prepare to start compressions.
- Dsuction the patient's mouth and give two more ventilations.
13Gastric distention will MOST likely occur:

- Bin patients who are intubated.
- Cwhen you deliver minimal tidal volume.
- Dwhen the airway is completely obstructed.
14If gastric distention is interfering with your ability to adequately ventilate a patient, you may have to:

15In MOST cases, cardiopulmonary arrest in infants and children is caused by:

16In two-rescuer adult CPR, you should deliver a compression to ventilation ratio of:
- A5:1
- B5:2
- C15:2
- D30:2
17Initial treatment to dislodge a severe foreign body airway obstruction in a responsive infant involves:
- Aback slaps.
- Boxygen.
- Cabdominal thrusts.
- Dblind finger sweeps.
18Most prehospital cardiac arrests occur as the result of:
- Asevere blunt trauma.
- Ba cardiac arrhythmia.
- Can acute ischemic stroke.
- Dobstruction of the airway.
19Several attempts to adequately open a trauma patient's airway with the jaw-thrust maneuver have been unsuccessful. You should:

20Signs of a sudden severe upper airway obstruction include all of the following, EXCEPT:
- Aacute cyanosis.
- Binability to speak.
- Cgrasping the throat.
- Dforceful coughing
21The impedance threshold device (ITD) may improve circulation during CPR by:
- Amaintaining increased intrathoracic pressure during the downward stroke of each chest compression, which forces more blood from both of the ventricles.
- Bmaximizing the amount of air in the lungs following chest recoil, which hyperinflates the lungs and forces more blood from the ventricle during each compression.
- Climiting the amount of air that enters the lungs during the recoil phase between chest compressions, which results in negative intrathoracic pressure and improved cardiac filling. Correct
- Ddrawing all of the air out of the lungs in between chest compressions, which causes positive intrathoracic pressure and a reduction of blood return to the right side of the heart.
22The main benefit of using a mechanical piston or load-distributing band device for chest compressions is:
- Athe minimal training required to correctly operate the devices.
- Bthe elimination of rescuer fatigue that results from manual compressions.
- Cthe elimination of the need to place a firm, flat device under the patient.
- Dits ability to be used with any patient, regardless of age, weight, or body size.
23The MOST appropriate treatment for a patient with a mild upper airway obstruction includes:
- Aperforming five back blows and five abdominal thrusts.
- Bvisualizing the airway and removing the obstruction.
- Cadministering oxygen and transporting immediately.
- Dadvising the patient not to make any attempts to cough.
24The proper depth of chest compressions on a 9-month-old infant is:
