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 needs additional information about the turning procedure?

A. The UAPs keep their backs straight and knees bent when moving the client. - This indicates the UAPs are following proper body mechanics for moving the client safely. B. A turning sheet is used under the client for turning and repositioning. - Using a turning sheet aids in reducing friction and facilitating smooth turning, indicating familiarity with proper procedures. C. An abduction pillow is placed between the client's legs when positioned. - This indicates awareness of the need to maintain proper positioning and prevent dislocation after hip surgery. D. The client is told to keep both legs straight and together while turning. - After a hip arthroplasty, it's crucial to avoid certain movements like keeping both legs straight, as this can stress the hip joint or prosthesis, indicating a need for additional information about proper post-operative positioning.
