A nurse is reinforcing teaching with the parent of a preschooler who has a hip fracture and is in a spica cast. Which of the following findings should the nurse identify as an indication of infection?

A. A hot spot on the cast may indicate localized infection. When the skin underneath the cast becomes infected, it can lead to localized warmth, tenderness, and redness. It is important to promptly assess and address the situation, as infections can progress quickly in these circumstances. B. General edema of the toes is a common response to immobilization and injury, but it does not specifically indicate infection. It is more likely related to inflammation or impaired circulation from the cast. C. Pruritus (itching) under the cast can occur due to the skin's reaction to the cast material, dryness, or moisture accumulation, but it is not necessarily an indication of infection. D. Pain at the fracture site is common and expected as the fracture heals, but it alone is not an indication of infection unless associated with other symptoms like fever, warmth, or drainage.
