Which of the following is a sign of infection in a wound?

A sign of infection in a wound commonly includes redness, swelling, and discharge. When a wound becomes infected, the body's immune response leads to increased blood flow to the area, which results in redness and warmth. Swelling occurs due to the accumulation of fluid as the body responds to the infection, and discharge may appear as pus or other fluids that indicate the presence of bacteria and an inflammatory response.

The combination of these symptoms is an important indicator for caregivers and healthcare professionals to identify potential complications and take appropriate action, such as cleaning the wound, applying appropriate dressings, or seeking medical intervention. Recognizing these signs is crucial in preventing further complications and ensuring the wound heals properly.
