How to handle a coworker always causing trouble

I have only been at this job for 2 months (first nursing job). I get along with everyone on my team, sometimes I work an extra day, and there is a nurse that works those days. She is always out to get someone in trouble. My friend works the same days as her and is still in orientation. The nurse has been getting her in trouble. The team leader for those days is this nurses best friend so they team up against her. My stomach gets so upset when I see her on the schedule the same days I work. I can't ask her anything without an attitude or rude remark. The sad thing is that this nurse has only been out of school for a year. Any advice?
Don't stoop to her level. Just do your work. If you need to ask her anything, just be polite and brief.

This thread has soooooo many good ideas! http://allnurses.com/nurse-colleague...ur-849657.html

I would make a comment to the supervisor if you have something SPECIFIC to discuss. You cannot complain on behalf of someone else. Also, suggest a solution. There is a lot of literature on this topic so you ought to be able to get some ideas off the Internet

Remember to be a professional. Do your work, learn from your mistakes, and act the professional you are. If you act and work like a professional then it will make the other whiners around you look like asses.
