What does bruising indicate?

• A. A closed fracture in the bone
• B. Discoloration of skin due to bleeding under it
• C. Infection at the injury site
• D. A type of allergic reaction

Answer: (B)

Bruising is a visible change in the color of the skin that occurs as a result of bleeding underneath the skin's surface. When blood vessels are damaged, usually due to trauma or impact, blood leaks into the surrounding tissues, leading to the characteristic purple, blue, or yellow discoloration associated with bruises. This response is a direct result of the body's inflammatory process as it works to repair the damaged tissue. In contrast, a closed fracture typically involves a break in the bone without causing visible deformities in the skin, while infection at an injury site usually presents with symptoms such as redness, warmth, swelling, and potentially purulent discharge. An allergic reaction would generally manifest with symptoms like hives, itching, or swelling, depending on the allergen involved, and would not typically include bruising as a primary indicator. Thus, recognizing bruising as a sign of bleeding under the skin is essential for understanding the body's response to trauma and injury.
