Nursing Negligence

My grandfather is 77 , in advanced stage 3 of Alzheimer’s and has 90% Black lung. He stays chronically ill, in the hospital litteraly every week. He has now become increasingly violent and delusional, so much to the point my grandmother can no longer contain him. My parents will not move him in because my grandmother has refused to do so.

Being how he is violent and uncontrollable for my grandmother. I suggested the possiblity of a nursing home where he could get the proper attention he needs. My grandmother has been in denial of this and refuses to admit he has Alzheimer’s despite the doctor’s report clearly stating it and hiself clearly showing it.

Yesterday he climbed ontop of a TV and tried to go out of a window, the TV fell on him but luckily he was pinned between it and a chair, thus not hurting him.

I know a lot of nursing homes are bad and mistreat patients, but I do not have any other solution since they will not agree on anything, what should I do?
Im going to add a few details to this dilemma that should be taken into consideration :

When I said my grandmother denies his Alzheimer’s I truly mean it. She has said everything from ” it’s beause he takes his oxygen mask off that he acts this way,not Alzheimer’s” or ” I think his blood sugar is up” despite him having no blood sugar problems in his history.

I hate to get personal but last night was the dilemma of him having ,er, bowel problems. He unfortunately decided to go everywhere, and I do mean everywhere. Doctor’s declared it Diarehha, her prognosis? ” I think he snatched a box of Exlax while I had him in the store!” I mean come on, it’s total denial and it’s not helping him or us.

The other topic has been a live in nurse? Well, she has refused that stating “THIS IS MY HOUSE” and went so far as to accuse my grandfather of infidelity with walk-in nurses. Truthfully? She’s the one with mental problems, but we can’t convince the doctors of this. My parents need POA.
