Which term describes a penetrating wound where the skin is pierced by a sharp object?

• A. Puncture
• B. Contusion
• C. Abrasion
• D. Laceration

Answer: (A)

A puncture wound describes a penetrating injury where a sharp object pierces the skin, creating a narrow channel that may extend deeper into tissue. This definition fits because the skin is breached by something sharp, leaving a small external opening but potentially significant internal damage. Other wound types come from different mechanisms: contusion results from blunt force with underlying tissue injury but no skin penetration; an abrasion is a superficial skin scrape from friction; a laceration is a tear or split in tissue, often with irregular edges. In practice, a puncture wound carries infection risk and possible hidden damage, so assess depth, look for a retained object, manage bleeding with direct pressure, cover the wound, and consider tetanus and imaging as needed.
