Sample item

Which feature most strongly supports a laceration rather than an incised wound?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Tissue bridges in the wound base

Lacerations result from blunt tearing of skin and underlying tissues, so they often have irregular bruised margins and tissue bridges in the base, unlike clean cuts made by sharp objects.

Option by option

  • A. Length greater than depth in every case

    Relative length and depth alone do not reliably distinguish all wound types.

  • B. Uniform absence of abrasion

    Associated abrasion may occur with blunt force and is not uniformly absent.

  • C. Clean sharply cut margins

    Clean sharp margins are typical of an incised wound.

  • D. Tissue bridges in the wound base (correct)

    Correct: tissue bridges are characteristic of blunt-force laceration.
