A nurse is caring for a preschool-age child who has a short-leg plaster cast applied 1 hr ago. Which of the following is an appropriate intervention

A. Restrict movement of the toes of the affected leg: Limiting toe movement is not necessary unless the toes are being injured. Encouraging gentle movement of the toes can promote circulation and prevent stiffness while the cast sets. Restricting toe motion unnecessarily can increase the risk of complications like decreased perfusion. B. Dry the cast with a hair dryer set on a warm setting: Using a hair dryer on a warm setting can cause burns or damage the cast material before it fully sets. Casts should be allowed to dry naturally, and heat sources should be avoided during the initial hardening period to prevent injury. C. Reposition the affected leg using fingertips: Touching or pressing on a newly applied plaster cast can cause indentations, leading to pressure points that may result in skin breakdown or impaired circulation. The cast should be handled minimally and supported rather than manipulated directly. D. Support the affected leg on a pillow: Elevating and supporting the leg on a pillow helps reduce edema, provides comfort, and promotes proper alignment while the cast sets. This intervention is safe and appropriate during the immediate postoperative or post-cast application period.
