Thank y'all for the replies. It is extremely frustrating, especially since I like her any other time and I get along great with all the other teachers. It did dawn on me today that I'm the first full time nurse they have had on this campus, that all the others only stayed half a day. I think in their absence she took a lot of the health stuff on herself and she's not ready to relinquish that.
I think I will send out a generic letter to all teachers (as not to single her out) and give a copy to my principles as well stating that if they feel a student has worsened in the time that I have seen them, to please send them back for re-evaluation. But for confidentiality reasons, to please refrain from coming to my office to ask specifics about a student and to please refrain from entering my office while any student is receiving treatment. Then if she continues, I will get the principles involved.
Hate to do it but that stuff has to stop! Especially when I see her do things that we as nurses are not allowed or have been taught not to do and then I have to argue with a parent why I can't do it but she could.
Thank goodness I'm going on maternity leave in a couple of months and will get a little break! I need one for my sanity!
