you have applied a zippered air splint to a patient's left arm. during transport, the patient complains of increased numbness and tingling in his left hand. you reassess distal circulation and note that it remains present. your most appropriate action should be to: a.remove the air splint and re-immobilize with padded board splints. b.inflate the splint with more air until the patient is comfortable. c.assess the amount of air in the splint and let air out as necessary. d.elevate the injured arm and reassess distal sensory function.
