In cases of wound infection, what reaction might be observed at the wound site?

1. Increased humidity

2. Surrounding erythema and tenderness

3. Decrease in pain sensation

4. No changes at all

The correct answer is: Surrounding erythema and tenderness

When a wound becomes infected, one of the hallmark signs observed at the wound site is surrounding erythema (redness) and tenderness. This reaction occurs due to the body's inflammatory response to the infection. As pathogens invade the wound area, the immune system responds by sending white blood cells to fight off the infection. This response often leads to increased blood flow to the area, causing the redness and warmth associated with erythema. Tenderness arises as the inflammation affects the surrounding tissues, resulting in increased sensitivity and pain. Other potential signs of infection can also include swelling, increased drainage, and the presence of pus. However, the specific combination of erythema and tenderness is a strong indication of an inflammatory response linked to infection, making this option the most relevant choice in the context of wound infections.
