Can MC give medication without approval of POA?

Reluctantly agreed to try dad (91, late stage Alzheimer’s and Parkinson’s) in memory care. I am POA. He was admitted as respite resident on Oct. 1st. I added additional month in view of recent events. When admitted he made comments about going home. Within first few days he fell unwitnessed. Dad fell 3 wks prior at home left unattended by caregiver. We stressed as soon as meds are given put him to bed because he gets anxious. Fell on his back with no injuries. Figured accidents happen. He appeared to be somewhat relaxed after asking to come home. Gave me peace of mind. Now last two wks, everything seemed to come to forefront. I received a phone call 3 days in a row, he tore his skin (like tissue paper on low dose aspirin), bruises on right arm, touching aides inappropriately. Spit out food so he’s isolated. Now sits by himself because he may spit on a resident. (Given puréed foods, sure way to tick him off. He loves to eat.) One day I’m being told he eats by himself, others he is fed by aides. If forcing food he doesn’t like, guaranteed to be spit out.
My dad remains combative on meds. Presently taking Depakote and Seroquel (which is also a high risk for fall med.) He takes Depakote 125 mg and Seroquel 50 mg. Both in AM and PM. At night Trazodone 50 mg. added to help with sleep. Seroquel was added to his meds approx 3 months ago. Low dose, increased dose after a month but not much of change shown to help combativeness in AM. At home slept through the night all under control except for combativeness in morning only. Now I’m told by some it’s all day (lunch, dinner time) and others say he sleeps most of the day???
Morning care is where the underlying problem lies. Dad does not want to get out of bed in the morning to get cleaned up for the day. Started at home when Hospice aides bathed him in bed. He was used to getting up to go to bathroom to get cleaned up. Dad was never morning person and asked to be bathed in afternoon. I thought Parkinson’s may be getting worse. I was trying to get to root of problem but since my sibling had to come to help me he suggested too much to handle at home and as stated above I reluctantly agreed to try respite residency. That’s when MC came to home to see dad’s combativeness in bed. Assurance given it can be handled and their facility is the place for him. Facility reported fall, tears to skin, when things occurred. Everything seemed to be copacetic first few weeks. Then phone calls “dad is fighting tooth and nail with two hospice aids so we are bringing in a psychiatrist”. A psychiatric nurse practitioner PNP evaluated him via telehealth. First the director of MC advised psych. came at lunchtime to evaluate morning care routine??? Director advised PNP that my dad is impulsive. Without actually seeing him in action PNP suggested Ativan Gel to rub on his wrist and/or behind ears. Claims this will calm him down enough for them to get him up and running but needed my approval. I advised her that I would need to talk to my nephew (recently completed residency for Psychiatry) and research.
I’m ok w/medications if they help, however dad already takes enough meds. He sleeps most of the time I visit and aides tell me he loves to sleep. Hmmm.?( I asked for a phy. clinical review of meds prior to admittance and nothing done).
Before approving I asked for zoom meeting to work together as a team. I was my dad’s primary caregiver alone and with help of aides (when good one stayed). I wanted to help with strategies I know worked at home and brainstorm to address triggers. The best they could do a phone call. No knowledge of what interventions used or how deescalated matters.
I asked to view my father’s medical records, where I discovered they gave him meds as early as 2/3wks prior without approval. I spoke with Hospice director a few days ago who advised no change in meds? MC notes noted I said their facility “may not be the one for my father.” It was said by Director of MC, not me!
