Hello, I am a medical student about to graduate and start residency, and I have a question. I always felt it was rude for doctors to call a nurse by their first name, and before I start residency at a new hospital I wanted to ask what the proper title is for an RN? Should I say "Nurse Smith?" or "Mr/Mrs Smith?" or something else? Its also frustrating to me that a lot of hospitals only display people's first name on their name badge, in this case would it be dumb to call someone Mr/Mrs/Ms John/Cindy etc .. or Nurse Cindy/John? I hate walking up to someone I don't know and calling them by their first name. I wanted to know if there was any convention in this case, and apart from that, what is the general nursing opinion. Thank you, and I'm sorry if I posted this in the wrong section.
