Final answer:
The nurse should praise the UAP for encouraging the client to move legs.
Step-by-step explanation:
The nurse should praise the UAP for encouraging the client to move legs. This action is appropriate because moving the legs can help prevent complications such as blood clots in clients who are on bedrest. It promotes circulation and prevents muscle atrophy. The UAP's behavior should be encouraged and supported as it aligns with the client's best interest.
