A Female Patient in Her Forties Has Overdosed and Is

A female patient in her forties has overdosed and is lying at the bottom of some stairs. As you arrive, her husband informs you that she is addicted to pain medications and was chewing a fentanyl (narcotic pain reliever) patch this evening. He states that she was having difficulty standing up and fell down the stairs. He is so frustrated with her that he immediately leaves the scene. The patient has snoring respiration and is incontinent of urine. You first step in caring for this patient would be to:

A) check her pupils for signs of a narcotic overdose.
B) open the airway with a head-tilt, chin-lift.
C) apply supplemental oxygen.
D) take manual in-line spinal stabilization.
