How would a nurse educate a patient about recognizing signs of infection post-surgery for a fracture?

The correct answer highlights the specific, localized signs of infection that a patient should monitor at the incision site after surgery for a fracture. Increased redness, warmth, swelling, and discharge are classic indicators of a potential infection. These symptoms suggest that the body is responding to a bacterial invasion, which could manifest as an inflammatory response.

By focusing on the incision site, the patient can identify problems early, allowing for prompt medical intervention, which is critical in preventing more serious complications such as systemic infection or sepsis. Recognizing these signs enables the patient to take an active role in their recovery and communicate effectively with healthcare providers.

While other options outline symptoms that could indicate a general illness or systemic issues, they do not specifically address the localized signs that are most relevant and critical for monitoring post-operative infection at the surgical site.
