The practical nurse (PN) observes two unlicensed assistive personnel (UAP) turning an older client who had a hip arthroplasty with prosthesis placement four hours ago. Which observation by the PN indicates that the UAPS need additional information about the turning procedure?

A. An abduction pillow is placed between the client's legs when positioned: Using an abduction pillow helps maintain proper hip alignment and prevents dislocation after hip arthroplasty. B. A turning sheet is used under the client for turning and repositioning: Utilizing a turning sheet reduces friction, protects staff from injury, and supports safe repositioning. This is an appropriate practice. C. The client is told to keep both legs straight and together while turning: After hip arthroplasty, especially with a prosthesis, the affected leg should be kept in proper alignment with abduction precautions, often requiring the legs to be slightly apart with an abduction pillow. Telling the client to keep legs together may risk dislocation. D. The UAPs keep their backs straight and knees bent when moving the client: Maintaining proper body mechanics prevents staff injury and supports safe client handling. This observation reflects correct technique.
