What does a bruise indicate about the underlying tissue?

• A. Swelling
• B. Fracture
• C. Contusion
• D. Infection

Answer: (C)

A bruise indicates a contusion, which is an injury to the underlying tissues without breaking the skin. When blood vessels are damaged due to trauma, blood leaks into the surrounding tissues, leading to the characteristic coloring of a bruise as it heals. This explains why "contusion" is the correct answer to the question. The other options suggest different conditions or injuries that do not accurately describe what a bruise represents. Swelling may accompany a bruise but is not a definitive indication of it. A fracture involves a break in the bone, which can sometimes be seen in conjunction with a bruise but is not directly indicated by the bruise itself. Infection involves the presence of pathogens and inflammation, which can manifest differently from a bruise, making it an unrelated option in this context. Thus, understanding that a bruise specifically signifies a contusion is essential in recognizing the nature of the tissue injury.
