Dad fell and fractured his hip. Was put into a Nursing Home on a short-term basis. Since his arrival he has been confused and delirious. We asked for an evaluation for dementia, and he was diagnosed with dementia. We believe this will turn into long term. I need to be the point person to assist in his care because my mother is elderly. She needs my help. The facility he is in now is an hour away. There are several facilities, with good reputations, closer to me.
I'm not sure he should be "diagnosed" with dementia until he's been give some time to come back around. And he may not, but you won't know until some time has passed.
Jan 2023 my 100-yr old Aunt with adv dementia fell in her home and broke her hip. She went to a reputable rehab clinic because she wasn't going to have any surgery to repair it, but they were trying to get her to the point of pivoting on it. Our family then realized that this is not the same as a NH or SNF. They would put her food tray in front of her and then assume she would feed herself, but she wasn't. Our family members had to do it because she was so out of sort in her new environment.
I'm just saying do not assume what the staff is able and willing to do for your Dad and don't assume it in a different facility. They cannot force him to do anything, including drink and eat. They can't force him to keep a fluids IV in. etc.
If you have the option of a family member going there to make sure he is getting/doing the basics regarding eating and drinking, it may help him get over the delirium. UTIs are extremely common in the elderly because of the changes in their physiology, and if your Dad had a catheter in at any point, increases the risk.

Your father would at some point qualify for the help of Medicaid, then, while some of your mom's assets were preserved for her own care.
You will need to decide who is to serve as POA for your father if he is competent enough to appoint one. If there is already a will a Springing POA would likely be in it appointing your mother. She could serve with your helping her, but record keeping is needed.
I would advise you to start a diary now of everything to do with your Dad on a day to day basis.
I sure do wish you good luck and am glad your mom has your support here.
