Which term describes a scrape to the skin due to surface friction?

• A. Laceration
• B. Incision
• C. Abrasion
• D. Penetrating wound

Answer: (C)

The main concept is a scrape caused by surface friction. An abrasion describes a superficial skin injury resulting when the skin is rubbed against a rough surface, removing the outer skin layer and causing a shallow wound with usually minimal bleeding. It’s typically limited to the epidermis and sometimes the upper dermis, presenting as a scraped, raw patch.

In contrast, a laceration is a tearing of tissue with irregular, jagged edges that can extend deeper; an incision is a clean, straight cut often from a sharp instrument; and a penetrating wound involves an object entering the body, which may cause internal injury despite a small exterior wound. Because the scenario specifies a scrape from friction, abrasion is the best fit.

In practice, treat abrasions by cleaning the area, removing debris, applying a sterile dressing, and monitoring for infection, while also considering tetanus status as needed.
