So on Friday when I visited dad the director informs me that dad, who is in a wheelchair, pulled one of the fire extinguishers from the wall, removed the pin and was spraying the floor. Today he got another off the wall, pulled the pin, messed with the hose but didn’t spray. The other is I put cookies, Carmel corn in ziploc bags and yesterday one of the aides caught him trying to eat the bag???
Or, it could be a reaction to medications. I'll bet he has been given some new drugs because of his illnesses. When the drug is out of his body the behaviors should stop.
It could also be the progress of his dementia. In that case the changes are permanent.
What was the result of your discussion with the head nurse?
