A friend has tripped and banged his knee on some rocks on the ground. He is bleeding from an open wound. What is the best response to this injury?

Place a clean dressing over the open wound and apply firm, steady pressure to help stop the bleeding. Covering it without pressure, as in choice C, may not control the bleeding. Calling 9-1-1 is appropriate if the bleeding is severe or does not stop, but the immediate response is to apply pressure.
