1 Do NOT remove an object such as a knife, stick, or arrow that is stuck in the body. Doing so may cause more damage and bleeding. Place pads and bandages around the object and tape the object in place.  Put pressure directly on an outer wound with a sterile bandage, clean cloth, or even a piece of clothing.
