A nurse is reinforcing teaching about cast care to a school-age child following application of a fiberglass cast for a radius fracture. Which of the following statements by the child indicates an understanding of the teaching?

A. Tingling in the fingertips is not normal and may indicate neurovascular compromise; this requires immediate evaluation. B. Placing an ice pack directly on itchy areas is unsafe; it can cause skin injury. Ice should only be applied to the outside of the cast with a barrier to protect the skin. C. Fiberglass casts typically dry within a few hours to 2 days, so this statement demonstrates correct understanding of cast care. D. Elevating the arm above heart level is recommended to reduce swelling, not letting it hang down, which can increase edema.
