Two weeks after cast application, a client with a fractured right arm returns to the clinic for evaluation. The client seems upset and tells the practical nurse (PN) that the healthcare provider said a callus has formed on the bone. Which action should the PN take?

A. Prepare to assist in applying a new cast to reduce pressure points: Recasting is unnecessary unless there is malalignment, skin compromise, or complications. Formation of a callus is a normal healing process and does not require a new cast. B. Explain that this is an expected part of the bone healing process: A callus is new bone that forms around a fracture as part of natural healing. Educating the client helps reduce anxiety and reinforces understanding of normal fracture recovery milestones. C. Report the client's concern to the healthcare provider: While documentation of client concerns is appropriate, reassurance and education about normal healing is the priority in this situation. There is no complication requiring provider intervention. D. Teach the client strategies to prevent further calluses: Callus formation at the fracture site is a desired outcome of bone healing, not a preventable problem. Interventions to prevent calluses are unnecessary and would be misleading.
