A client diagnosed with a fracture of the left ulna undergoes an open reduction procedure. Postoperatively, a plaster cast is placed on the client's left arm. Which client statement requires an intervention by the nurse? (Select all that apply.)
1. The cast will be fully dried in the next few hours.
2. The cast should be covered to promote drying and prevent cracking.
3. Tape can be layered on rough areas of the cast to avoid pinching.
4. It is best if I elevate my arm and cast on a plastic-covered pillow.
5. Avoiding pressure on the cast is very important at this time.
