Which of the following is NOT a sign of infection at a surgical site?

Decreased mobility is not typically considered a direct sign of infection at a surgical site. Instead, decreased mobility may arise from pain or discomfort associated with the surgical procedure itself rather than an infectious process. Infections at the surgical site commonly manifest through physical signs such as redness, swelling, and warmth.

Redness indicates increased blood flow to the area, which is often a response to infection. Swelling can occur due to the accumulation of fluid, which can be a result of inflammation associated with infection. Warmth in the area often signals an increased metabolic response due to infection as well. Together, these signs can alert healthcare professionals to the potential presence of an infection, while decreased mobility is more of a symptom of the patient’s overall condition post-surgery.
