Advice on difficult resident/vent - sorry for length!

I need advice on a resident who is currently on my floor. I also need a 1-2 part vent about this resident!

Bit of background, I work on a 32 bed unit, mostly LTC and some short-term rehab. We have "Santa Claus" in one of our rooms (named for his white beard). This man's baseline is to be a royal terror. He is not physically abusive, but he often times gets agitated, is EXTREMELY needy, and can at times be verbally abusive. He complains when he can't get a cup of coffee at 2am, when he has his PA on, when his heels hurt, and how he cannot sleep. All of the staff, including myself as the Supervisor RN on 11-7, have been more than accomodating to this man. The trouble is, I can't figure out a way to get him to calm down or quiet down. He is supposedly HOH, and is overly disturbing to the other residents in his room and throughout the floor. He gets very loud and wakes everyone up around him. If I ask him kindly to keep his voice down, he gets worked up. He gets louder.

We have tried so much to get this man stable emotionally/mentally. We've had success with ABHR gel in another hospice resident, and have begun administering that PRN with no effect. He takes Seroquel 25mg QID and q4 PRN. No effect. He gets 0.5 of Ativan at HS. No effect. I am at my wits end with this man. Even my ADON agrees that he is hard to handle. And she usually thinks everyone has a UTI or has to be saved!

Part two of my story and vent deals with a resident across the hall. He is in his 50's, here for rehab secondary to a TMA of the right foot. I heard this man yelling last night, which is not his norm. I go in and hear him cursing like a sailor. He is sick of the guy across the hall, wants to beat him over the head with his cane because he "has no respect for anyone else." He is tired of PT deeming walking down the hall and walking up a few stairs "rehab." He is an A+Ox3 guy who is stuck on a floor of nut jobs and sickies. I really did feel for this guy, he told me he didn't belong here and that he thought he should write to the paper to get them to investigate why someone in his state would be placed at my facility. I had no clue how to respond to him. He apologized and told me it was nothing against me.

So basically Santa Claus is causing an uproar all day every day with his demands and inconsolability, and it's really starting to grind on my other residents. I'm trying to come up with ideas to calm Santa, but I can't think of much else. It's almost impossible to do a 1:1 with him, we don't have that kind of staffing or time. How can I console my A+O gentleman despite the fact that I agree that he doesn't belong in this unit?

Thank you for listening
