What type of injury does a contusion represent?

• A. a minor scrape
• B. a bruise caused by blunt force
• C. a surgical complication
• D. a severe cut

Answer: (B)

A contusion represents a bruise caused by blunt force. This type of injury occurs when blood vessels under the skin are damaged due to trauma, such as being hit or bumped. The force from the impact causes bleeding within the tissues, leading to the characteristic discoloration and swelling associated with bruises. Contusions can vary in severity depending on the extent of the damage to blood vessels and surrounding tissues, but they are primarily recognized as non-penetrating injuries that do not break the skin's surface. Context around other choices highlights that a minor scrape refers to abrasions where only the top layer of skin is removed, a surgical complication would relate to issues arising from a surgical procedure that aren’t directly related to blunt force trauma, and a severe cut indicates a laceration that breaches the skin layers, which is different from a contusion as it involves an open wound rather than internal bleeding. Thus, recognizing a contusion specifically as a result of blunt force trauma helps differentiate it from other types of injuries.
