What type of extraction tool is best to use to open hoods, trunks, and doors?

A 28-year-old male was cutting limbs from a tree when he lost his footing and fell 20 feet. He is unresponsive and breathing very poorly, at 28 times per minute. His radial pulse is weak and thready, and his skin is cool to the touch. Emergency Medical Responders (EMRs) have placed the patient on a nonrebreather face mask and are holding manual cervical spine motion restriction. A blanket has also been applied and covers the man. Based on these assessment findings, which instruction would you give to the EMRs?

A) "Since he is unresponsive, let's open the airway with the head-tilt, chin-lift maneuver." B) "Let's uncover him since increased temperature will dilate his blood vessels and drop his BP." C) "Let's move him to the stretcher for immediate transport to the hospital." D) "Let's take off the oxygen mask and start positive pressure ventilation to assist his breathing."
