What are the four basic wound types commonly seen in battlefield injuries?

• A. Abrasion, laceration, puncture, and avulsion.
• B. Burn, blister, cut, bruise.
• C. Scrape, slice, tear, fracture.
• D. Puncture, incision, contusion, edema.

Answer: (A)

Wounds are categorized by how the tissue is disrupted, and on the battlefield the four basic wounded types are abrasion, laceration, puncture, and avulsion. An abrasion is a surface scrape of the skin, usually shallow but dirty. A laceration is a torn, irregular wound with tissue bridging, often jagged. A puncture is a narrow, deep wound produced by a pointed object, which can hide its depth and trap debris. An avulsion involves a portion of tissue that’s torn away, sometimes with significant tissue loss and bleeding. This set captures the common mechanisms you’ll see in combat injuries and directly informs how you approach cleaning, debridement, dressing, and assessing for damage.

The other options mix injury types that aren’t part of the standard four basic battlefield wounds. Burns and blisters are thermal or friction injuries; contusions are closed injuries (bruises); edema is swelling rather than a wound type; and incisions describe a clean, straight cut which isn’t grouped with the four basic wound categories used in field trauma.
