An injury that separates soft tissue layers and results in a complete detachment or skin flap is called a(n):

• A. Laceration
• B. Contusion
• C. Abrasion
• D. Avulsion

Answer: (D)

The idea being tested is recognizing an avulsion, a severe soft-tissue injury where tissue is torn away from the body, producing a skin flap or a completely detached piece. This description fits avulsion because the key feature is the separation of tissue that may leave a flap of skin still attached at one edge or entirely detached from its normal connections. Understand how it differs from other injuries: a laceration is a cut through tissue that may be jagged but remains attached; a contusion is a bruise with underlying tissue damage but no break in the skin; an abrasion is a superficial scraping that wears away the surface skin. The defining aspect of an avulsion is the actual tearing away of tissue with a possibility of a flap being left behind or the part being completely separated. In terms of care, prioritize stopping bleeding and protecting the wound. If a flap is present, avoid tearing it away or rearranging it. Keep the area clean if possible, and cover with a sterile dressing. If the detached piece can be conserved, place it in a clean moist dressing inside a sealed bag and keep it cool while you transport. Treat for shock as needed and seek rapid transport to a hospital.
