What are common signs of wound infection after surgery?

The correct choice highlights the typical signs that indicate a wound infection following surgery. Redness, swelling, increased pain, and purulent drainage are all classic symptoms that suggest the presence of an infection in the surgical site.

Redness around the wound can be a sign of inflammation, indicating that the body is responding to an infection. Swelling often accompanies inflammation and can hinder the healing process. Increased pain at the site is also a common indicator of infection, as the body tends to experience heightened sensitivity in response to an underlying issue. Purulent drainage refers to the presence of pus, a fluid that typically contains bacteria, dead cells, and other components related to an infection, signaling that intervention may be necessary.

While fever, chills, nausea, and vomiting can indicate a systemic infection or other complications, they are not uniquely indicative of a wound infection. Loss of appetite and fatigue, although they can occur in sick patients, are also nonspecific and do not directly imply a localized wound infection. Good wound healing and no discomfort would suggest the absence of infection rather than the presence of it. This reinforces the understanding that the specific signs mentioned in the correct answer option are critical for identifying wound infections effectively.
