My Mom had a stroke almost a year ago. I have her POA.

Mom has a rather good mind to have gone through all she has been through. There was a misunderstanding with the workers (they gossip like crazy) and a friend made ( Mom ) a friend since has been there. . This really had little to do with my Mom. The director of nurses called me and ask me some questions and I thought that was the end. They went to bingo (nurse and social worker) took mom into a small private room and started questioning her. This is after 3 phone calls to me from the director of nursing. I had no idea they were going to have such a meeting. When I ask if it was legal for Mother to be questioned like that( no one with Mom) they got all upset but didn't know the answer. I do not know the answer either. Can you pl;ease tell me if they were within their rights. Thank you, Alabama
