Which open soft-tissue injury is limited to the superficial layer of skin and results in the least blood loss?

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

Answer: (A)

Injuries are ranked by how deep they go into the skin and what tissues are involved. The most superficial and typically associated with the least bleeding is an abrasion, which only removes or scrapes off the outermost skin layer (the epidermis). Because it doesn’t reach the deeper, blood-rich tissues, the bleeding is usually minor—often just a light oozing. Abrasions look like scrapes or road rash and may be dirty, so cleaning and dressing are important to prevent infection. Basic care includes gently cleaning the area, stopping any minor bleeding with light pressure if needed, and applying a sterile dressing. Also consider tetanus status if the wound is contaminated. In contrast, deeper cuts that extend into the dermis or beyond (lacerations), punctures that penetrate inward, or avulsions that tear away tissue can involve more tissue damage and bleed more heavily.
