Which of the following are signs of infection in a wound?

The presence of red striations and discharge from a wound are signs of infection because they indicate that the body is responding to an infection process. Red striations, or redness that extends from the wound, suggest that inflammation is occurring, which can be a response to pathogens entering through the wound. Discharge, especially if it's pus or has an unusual color or odor, is a clear indicator of infection, as it typically contains bacteria, dead cells, and white blood cells that are part of the immune response.

Understanding these signs is crucial in emergency response situations, as prompt recognition of infection allows for timely medical intervention, which can prevent complications. The other options represent typical signs of healing or normal responses rather than indicators of infection.
