What is the correct term for an open wound that has jagged skin edges?

1. Incision

2. abrasion

3. Laceration

4. Puncture

The correct answer is: Laceration

A wound characterized by jagged skin edges is referred to as a laceration. This type of injury is typically caused by a blunt object or surface that tears the skin rather than cutting it cleanly, which is what happens in an incision. The jagged nature of the edges associated with a laceration can complicate healing and increase the risk of infection, as the irregular surface can harbor bacteria and debris. In contrast: - An incision is a clean cut usually made by a sharp object such as a knife or surgical instrument, featuring smooth and even edges. - An abrasion refers to a superficial wound where the outer layer of skin is scraped away, often resulting from friction against a rough surface, without the jagged edges seen in lacerations. - A puncture is a small but deep wound caused by a pointed object, which does not typically have jagged edges as it creates a narrow opening. Understanding these distinctions is critical for accurate assessment and management of wounds in emergency situations.
