Emergency Medical Technician (EMT) Trauma Practice Test

In contrast to an incision, a laceration usually:

1. Bleeds more severely

2. Involves an artery

3. Is a jagged cut

4. Is a superficial injury

The correct answer is: Bleeds more severely

An incision is a clean, straight cut made with a sharp object, while a laceration is a jagged cut caused by a non-sharp object. Therefore, compared to an incision, a laceration is more likely to have rough and uneven edges that can cause bleeding to be more severe. Option B is incorrect because although a laceration may involve an artery, it is not always the case. Option C is correct but does not directly answer the question, as both a laceration and incision can be considered a type of jagged cut. Option D is incorrect because a laceration can be a deep and serious injury, not just a superficial one. Therefore, option A is the best answer that highlights a key difference between an incision and a laceration.
