The first problem here is the staff calling police and an ambulance. Increased aggression and combativeness is part of the progression of Alzheimer's. If you as a staff, on a locked Alzheimer's unit cannot handle it then you shouldn't accept the patients to begin with. Or here is a good idea, instead of calling the cops, how about 5mg of Versed IM and four point restraints and call it a day.
Poor NH care is to blame for this.
^THIS is totally correct.
