You arrive at the scene of a shooting. The patient, a 19-year-old man, has a gunshot wound to the side of his head with a large amount of exposed brain matter. Further assessment reveals that the patient is apneic and pulseless. Law enforcement personnel advise you that the person who shot the patient is in their custody. You should:

A) begin resuscitative measures at once and contact the patient's family to determine if he is an organ donor. B) begin CPR immediately, cover the wound with a bulky dressing, and prepare to transport the patient. C) avoid unnecessary contact with the patient and document the findings of your visual assessment of the patient and scene. D) place plastic bags over the patient's hands, apply a cardiac monitor to confirm asystole, and notify the coroner's office.
