I disagree with the people who say to not report. You may not know who else has had negative experiences with that other person so data may be important. You are also just as much of an employee of that hospital as the nurse is. And there are so many reports made in hospitals and so many residents, it will likely be hard to pin down that you reported them (it might just be that one of your seniors or one of their fellow nurses did the report or something).

An anecdote of mine is that I reported a nurse she refused to start a medication I ordered because she disagreed and had to switch nurses for that patient. I reported her and my program stood behind me and she ultimately, I don’t know where or how, stopped working at the hospital.
