Sample item

What wound pattern is most consistent with injury from a sharp-edged object drawn across skin?

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

The answer and the reasoning

C. Clean incised wound with regular margins

A sharp edge divides tissue cleanly, producing an incised wound with regular margins and little surrounding abrasion; depth is usually less than length unless special circumstances apply.

Option by option

  • A. Puncture wound from a pointed object

    A pointed weapon produces a stab or puncture wound rather than an incision.

  • B. Irregular laceration with tissue bridges

    Tissue bridges indicate tearing by blunt force.

  • C. Clean incised wound with regular margins (correct)

    Correct: a sharp cutting edge creates a clean incised wound.

  • D. Contusion without skin breach

    A contusion is closed soft-tissue haemorrhage without a skin cut.
