13. Detail the steps for a figure-eight wrap. Assemble needed supplies. Carefully place dressing over wound area without contaminating. Anchor bandage with one or two turns around palm of hand. Roll gauze diagonally across front of wrist and in figure-eight pattern around the hand. Tie off at the wrist. Discard contaminated materials and gloves in biohazardous waste bag.
14. How do you remove sterile dressings? The first step in changing a sterile dressing is to remove the old one. Tape may be pulled off, but it should be pulled in the direction of the incision, so as not to reopen the wound. Cut bandages free using scissors, being careful not to go near the incision to prevent the wound from accidentally reopening. If the dressing sticks because of dried blood or fluids, soak the dressing with sterile water or saline solution to work the dressing free. After the wound is uncovered, the physician will inspect the wound. At this time, change gloves to avoid contaminating the wound with bacteria from the old bandage.
