  B) Take and maintain manual inline spinal stabilization.
  C) Expose and splint both legs to prevent further injury.
  D) Open the airway using the head-tilt/chin-lift.

Question 2

Higher levels of exhaled carbon dioxide indicate hypercapnea, which is often due to:
 
  A) hyperventilation syndrome.
  B) inadequate ventilation.
  C) excessive BVM ventilation.
  D) adequate ventilation.

Question 3

Management of a traumatic fracture of the femur should include:

  D) application of traction device, application of the PASG, immobilization using the longboard, transport to emergency department.

Question 4
