Which statement best differentiates an incisional wound from a stab wound?

• A. Incisions are longer on the skin than deep.
• B. Incisions are deeper than the surface length.
• C. Stab wounds are longer on the surface than depth.
• D. Stabs are shallow and short.

Answer: (A)

The key is how the wound’s surface length compares to its depth. An incisional wound is made by a blade sliding across the skin, producing a relatively long cut that isn’t very deep—the surface length is greater than the depth. That’s why the statement describing incisions as longer on the skin than deep is the best fit. A stab wound, by contrast, is typically deeper than its surface length because a pointed instrument penetrates more into the body, creating a longer wound track than what’s visible on the surface. The other options mix up this relationship or oversimplify stabbed wounds as shallow, which isn’t necessarily true.
