If a patient's right leg has been severed from their body, what type of injury is this?

The correct response identifies the injury as an amputation because this term specifically describes the complete removal of a limb or part of a limb from the body. In the context of the scenario given, where a patient's leg has been completely severed, it illustrates a clear case of amputation. This terminology encompasses both traumatic and surgical removals.

In contrast, laceration refers to a tear or deep cut in the skin or flesh, which does not imply the total loss of a body part. Abrasion involves a superficial scrape that damages the outer layers of the skin but does not penetrate deeper tissues or remove any body part. Evisceration pertains to the removal of internal organs from their normal position, particularly in the context of a surgical procedure or traumatic injury, which is not applicable when discussing the severance of a limb. Thus, understanding these definitions highlights why amputation is the appropriate classification of the injury described.
