My dad went into a nursing home for a 1-2 week stay to use their physical re-hab wing for strengthening his legs.funny you say that I had just edited my post to include that possibility
He was 84 and wasn't on any prescribed medications.
On his 2nd night there he was given "Haldol",when I visited him the next morning he was asleep and they told me he was "agitated" and the nursing home doctor prescribed it..She never even met him ,no less knew anything about him.
Giving Hadol was their go-to policy.
I woke him up and had brought in a delish breakfast from home for him.
As he was eating he aspirated ( unbeknownst to me) and soon after stopped breathing.
I screamed or the nurse, they threw me out of the room and I called 911 and got him as he lay unconscious across the street to the hospital.
He never regained consciousness ( except for a midnight squeeze of my hand) as I lay next to him on a cot) and passed away the next morning about 10:30 am.
