A nurse is caring for an adolescent client who has a fractured right tibia and a cast. Which of the following findings should the nurse report to the provider?

A. Swelling in a dependent position is expected due to gravity and should reduce with elevation. B. Pain following range-of-motion exercises can be normal after a fracture, but persistent or severe pain should be monitored. C. Coolness of the toes indicates impaired circulation, which can be a sign of compartment syndrome or cast tightness and requires immediate medical attention. D. Pruritus under the cast is a common complaint and can be managed with appropriate measures but does not require urgent reporting.
