Which type of wound has a higher risk of infection than others?

• A. Abrasion
• B. Laceration
• C. Puncture wounds
• D. Avulsion

Answer: (C)

Infection risk hinges on how deep a wound goes and how well it can drain. Puncture wounds create a small opening that penetrates deeply into tissue, often with little bleeding and poor drainage. Bacteria carried on the penetrating object end up far inside the tissue, where blood supply is limited and the immune response is harder to mobilize. That trapped, low-ventilation environment is a prime setup for infection and sometimes abscess formation. The object that caused the puncture (like a nail or needle) can also introduce soil, dirt, or other contaminants directly into the wound. Abrasion injuries are more superficial and have a larger surface area exposed to cleaning and antiseptics, which helps prevent infection. Lacerations involve tearing with exposed tissue and usually provide more opportunity for cleaning and drainage. Avulsions involve tissue tearing or loss and can be contaminated as well, but the distinctive combination of deep penetration with minimal drainage makes puncture wounds the most prone to infection.
