you have arrived on the scene of a large structure fire. emergency medical responders (emrs) are by the side of a patient who is responsive to verbal stimuli and has significant burns to his body. they report that the patient fell down a flight of stairs while trying to escape and was trapped for several minutes. their assessment findings include partial- and full-thickness burns to his right arm, right leg, and right side of the face. the emrs also report that the patient's unburned skin is cool, clammy, and pale, with a delayed capillary refill. his pulse is 144 beats/min, respirations are 22 breaths/min, and blood pressure is 88/50 mmhg. which instructions would be most appropriate?
