You are assessing a young male patient who is responsive to painful stimuli and breathing agonally after being ejected from an automobile at a high rate of speed. His pulse is weak and thready, and his skin is cool and diaphoretic. When addressing his airway and breathing, the EMT must immediately:
A) administer oxygen at 15 lpm with a nonrebreather face mask. B) perform the jaw-thrust and begin artificial ventilations with the bag-valve mask. C) immobilize him to a long spine board, and then start positive pressure ventilation. D) open the airway using the head-tilt, chin-lift and begin ventilations with the bag-valve mask.
