A young female patient involved in a motor vehicle collision responds to painful stimuli by extending her arms and legs. Her airway is open and breathing shallow and irregular. A radial pulse that is moderate in strength is palpated. Her pulse is 64 beats per minute, respirations are 8, and blood pressure is 210/110 mmHg with an SpO2 90. She has noted deformity to her forehead and a left pupil that is dilated and does not respond to light. Manual in-line stabilization is being held by Emergency Medial Responders (EMR). At this time, the EMT's priority action is to:
A) apply a nonrebreather face mask with high-concentration oxygen.
B) start positive pressure ventilation at 20 breaths per minute.
C) perform the secondary assessment to identify additional injuries.
D) apply a cervical collar and transfer to the stretcher for immediate transport.
