My wife is a nurse, I have worked around nurses most of my working life and I know the psychology of nurses - so trust me when I say that no way I could've put it where it would not sound patronising to a nurse. They have a chip on their shoulder psychologically, it makes them either great nurses or nutty as hell.
But nurses, even the most elite ones, lack the education in medicine to weigh in on surgical prognosis - if she's indeed a trauma, step down surgical unit or ortho nurse then she will have undoubtedly gained a great deal of experience but only the proactive nurses get educated through those years. Some nurses would've made great physicians, but then again great nurses are vital - I'm encouraging my wife to become a Nurse practioner, it's is a great profession & meld of the two
