Penetrating wound corresponds to which of the following?

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

Answer: (A)

A penetrating wound means something has entered the body, piercing the skin and deeper tissues. A puncture wound is a classic example: a pointed object creates a small entry hole but can drive deep into the body and damage underlying structures. This matches the idea of a penetrating injury because the wound results from an object entering rather than just cutting or scraping tissue. In contrast, a laceration is a tearing wound with irregular edges from blunt trauma, an abrasion is a superficial skin scrape, and an incision is a clean, deliberate cut with smooth edges. So the best match for a penetrating injury is a puncture wound.
