The third person narrative is a little hard to understand. What i'm understanding is that New Graduate RN- Grad is working with experienced Preceptor RN. One or both of the RN's made some kind of fairly serious mistake / omission. RN-Grad intended to report the mistake to manager, doctor or incident report as per the unit policy, RN Preceptor convinced her not too, and hide mistake instead. Shift finished. RN - Grad and RN Preceptor went home. Facility somehow found out.
I would honestly assume that the RN Preceptor was also fired. But I guess if RN Preceptor just reported the mistake of the RN-Grad and the fact that this licensed RN broke protocol by hiding/ failing to report her own mistake, the rest of it is just one person's word against another's. It would makes sense that they accepted the report of their senior RN and only fired the RN Grad who did not report it.
I'm actually sorry for the RN- Grad that she choose to follow bad advice (covering up a mistake) Knowing nothing about the actual incident I assume the hiding the mistake was why she was fired, rather than the actual mistake. It can be hard as the junior person to go against someone senior to you, but as a license professional it is actually expected of you. I don't really see that a lawyer would be much help, but i'm not a lawyer. I would think the best you can hope for is that they won't go after you for the $10 000
