You arrive at a hunting camp for a hunter who stumbled over a rock and caught himself on his outstretched arm. He denies hitting his head or neck. There are no threats to the airway, breathing, or circulation. He has swelling and ecchymosis to his left wrist. A radial pulse is readily palpated and the skin in the hand is warm to the touch. Which one of the following instructions given by the EMT to other rescuers indicates proper care of this patient?
A) After we splint his wrist, we will need to elevate it during transport to decrease the opportunity for swelling.
B) When you splint that arm, make sure that it is somewhat loose so the patient can move it if he becomes uncomfortable.
C) Make sure to wrap that splint as tightly as you can; we need a lot of pressure to prevent additional swelling.
D) Since he still has a pulse in that arm, the swelling must be from a muscle injury. We can forego the splint and just apply ice packs.
