You can submit a question to your state board of nursing with out having to name names if you are wondering what the penalty would be. You could then show her the answer, and also show her the sections of the nurse practice act in your state that apply. You can find these on line. If you are her boss, then as a manager, you can deal with this as another poster has suggested, because you are right and she is in the wrong. Your administration should back you on this. Also your company may even have a policy on this, so you can bring this to her as a improvement plan as a part of her evaluation. If she does want to be a nurse then she needs to learn what professionalism is all about.
