I knew two nurses who were railroaded out of jobs (and nearly lost their licenses) because of false allegations by LTC patients who were just beginning to be Sundowners and thought they'd "get even" for issues like being too slow with a sleeping pill.
I know because I was there, and I was nearly a victim of one of these guys also.

One of them actually discussed the event with me and finished with, "I just don't like her. She should lose her job for not moving fast enough."
That nurse was out of work for months until the BON addressed the issue and finally cleared her. She nearly lost her home (and her mind with fear and worry) and had to go before the BON without any representation.
The other nurse was fired after the "investigation" by administration and reported to the BON. I don't know what happened to her, but a year later, I was working at the desk with another nurse who was on duty that night, and that nurse told me a completely different version of events than had been circulating in the facility. In other words, that the event HAD happened, but the offender was a different nurse completely.
I figured if it could happen to them, it could happen to me, or you, or anyone, and no way was I going to ever face the BON alone and lose my livelihood over some capricous whim of a family, patient, or management.
