Sexual Assault Nurse Examiner (SANE) A Practice Exam

Which of the following is a characteristic of lacerations?

1. Surface-level injuries

2. Deep tissue injuries

3. Injury caused by scraping

4. Pressure-induced injuries

The correct answer is: Deep tissue injuries

Lacerations are defined as injuries that result from the tearing or cutting of the skin and underlying tissues. This type of injury is typically characterized by a depth that can extend into the dermis, subcutaneous tissue, or even deeper structures like muscles or organs, depending on the severity and mechanism of the injury. Therefore, the correct answer highlights that lacerations can involve significant damage beyond just the surface, often presenting with irregular edges and potential complications such as infection or scarring due to the trauma. When considering the incorrect options, surface-level injuries refer to abrasions or other minor injuries that do not penetrate deeply into the tissue. Injury caused by scraping generally defines abrasions as well, which remove only the superficial layers of the skin. Pressure-induced injuries, commonly known as pressure ulcers or bedsores, arise from sustained pressure on the skin, typically in areas over bony prominences, and are distinct from lacerations, which are caused by sharp objects or trauma rather than prolonged pressure.
