I just graduated, and will be starting work in June. While I was in school and doing clinical rotations, I saw lots of behaviors from "seasoned" nurses that I consider unprofessional. Some things I discussed with my instructors because it really bothered me, since it goes against what we were being taught in school.
The best advice I was given echoes MR Chicago RN. As nurses, we need to set an example for others in our profession. If you see issues with another nurses actions, do not be afraid to discuss it with them (in an appropriate manner). Tell them why it bothers you, and give them a rationale for why it isn't appropriate. Teach them how it affects patient care. Ask them to think about their actions, comments, etc., and offer suggestions on what an appropriate action would be. Just because you are a new grad does not mean you don't know what is right! If the problem does not resolve, do not be afraid to go to your manager or team leader to discuss it (they may not know it is a problem), but let the person you are having issues with know that you are going to discuss the problem with a supervisor first, otherwise you will create unnecessary resentment and animosity. They may still be angry at you for reporting them, but they will respect you for letting them know in advance they are being reported.
HIPPA issues should be stopped immediately. If you see a confidentiality breach, speak up and tell them to stop their discussion. If they continue, report the people immediately.
I understand the need to vent about a difficult patient or family, but in reality, if discussed with other people who know who you are talking about, it is a HIPPA violation. If you need to vent talk about how YOU are feeling, not about the actions of the patient or family. If you REALLY need to talk about a particular person, go to your supervisor.
Remember about pain, what is a 2 to you may be a 10 to someone else, and every culture and individual demonstrates pain differently. If its a real problem discuss the need for an "in-service" for the nurses about pain manifestations. All pain complaints should be treated as legitimate issues and all patients should be treated with respect no matter what their circumstances. "Drug -seeking" is a bad word as far as I am concerned, even if the patient is a "frequent flyer" with a history of addiction. Addiction is a disease, and if you are really concerned, discuss it with the MD, and talk to your patient. You may find thay want help, but don't know where to go or how to ask.
Always be an advocate for your patients!
Good luck, and I hope that wasn't too "preachy", it's just an issue I feel very strongly about.
