Should a wheelchair be the reason she is removed from the ACU?

A fellow caregiver asked...

My Mom has mild demetia, and was in Acu, where she was very active. She loved her new home. She also has a disk on her back that can make her walking difficult, but she can walk but only short distances, then she needs the help of a wheelchair. My question is this...Should a wheelchair be the reason she is removed from the ACU? The unit she is in has changed her for the worse..cries, won't eat, and spends all day in a wheelchair, which keeps her from walking at all!!! I need help. I already notified the Cop, office..even they do Not get back to me. She needs to go back to the ACU, because I can't stand her this way. Where do I go from here?
