What are common signs indicating an infection in a wound?

In the context of wound infections, increased redness, warmth, and purulent drainage are classic signs that indicate an infection is present. When a wound becomes infected, it often exhibits these inflammatory responses as part of the body’s immune reaction.

Increased redness around a wound signifies that blood flow has increased to the area, often due to the inflammatory process. Warmth is also a result of this increased blood flow, which brings immune cells and nutrients to the site to combat the infection. Purulent drainage, characterized by yellow, green, or white fluid, indicates the presence of pus, which is formed from the accumulation of dead white blood cells, bacteria, and tissue debris. These signs collectively suggest that the body is actively responding to an infection, making option B the most accurate representation of common indicators of wound infection.

In contrast, other options do not align with typical signs of infection or represent conditions that may be present in non-infected wounds, which is why they are not appropriate choices.
