Which of the following signs may indicate an impending infection in a burn patient?

The presence of fever and increased purulence is a significant indicator that an infection may be developing in a burn patient. Fever often signifies that the body is responding to an infection, as it activates the immune response to combat pathogens. Increased purulence indicates the production of pus, which is a common manifestation of infection, suggesting that there is an accumulation of bacteria and dead cells at the site of the burn.

Recognizing these signs is crucial in managing burn patients, as early detection of infection can lead to prompt treatment, potentially preventing further complications. Monitoring these symptoms allows healthcare providers to take necessary actions, such as starting antibiotics or evaluating the burn for further intervention.

In contrast, decreased pain might suggest a number of factors unrelated to infection, including nerve damage or a reduction in inflammation. Increased appetite typically indicates general well-being and recovery rather than an impending infection, and improved wound healing is a positive sign that indicates the patient is recovering, rather than signaling an infection.
