The correct answer is exudate. The presence of any level of exudate indicates that there may be some underlying pathology, such as infection, occurring in the wound bed. Exudate is a fluid that drains from wounds, and its characteristics can provide essential clues about the wound's condition. If an excessive amount of exudate is present, or if it is purulent (containing pus), it often suggests that the wound may be infected.

In contrast, while redness can be a sign of inflammation, it doesn't specifically indicate infection on its own, as redness can occur in non-infected wounds as well. Adhesive is not a relevant indicator of infection in the context of wound care, and necrotic tissue may suggest that the wound is unhealthy, yet it is not definitive evidence of infection. Understanding the nuances of exudate and its implications helps clinicians accurately assess and manage wound healing and treatment strategies.
