Forget the driver’s license; why was she allowed to be a nurse?
I am a retired nurse. Once you get your license, no questions are asked about mental status .The only way a nursing board finds out that a nurse is mentally ill is if someone reports it, like a coworker. An arrest record can be discovered if you are a traveler working in a different state ( applying for a first time license in that state)because usually they will do a criminal record search. But that only works initially, once you have your license they don’t check.
