yes, if there's enough information given to identify the patient. that would be the key. I imagine, since no names were mentioned. Seeing this nurse worked all over a vast area with a few nursing agencies, and not in one home care setting, one office or hospital there seems there would not be enough evidence to track whom she was speaking about. That's the information I have gathered thus far. I bet it really depends on a few factors when it is investigated for technicalities. However speaking in a public place is always a bad idea no matter what. Lessen learned for her.
