She rejects caregivers

My wife needs assistance to get out of bed, showered, and dressed. She is suffering from mid stage O(or later) FTD and recovering from a broken femur. I hired an excellent service to send home healthcare workers to hep her in the morning and to assist in the afternoon to get her to the dining room in our retirement building, then to get her ready for bed. The morning nurse told me yesterday I may as well cancel the a.m. care because she wastes most of the time trying to convince my wife to get up, showered, and dressed. The p.m. routine has become a similar story. Convincing her to get ready for bed evolves into delays and outright refusal to cooperate. i know this is the dementia we are dealing with but the behavior makes all the caregiving efforts seem futile. I fear that if I place her in a nursing home she will completely waste away. My pre-dementia wife would not want any of this nor would she ever see herself behaving as she does.
