There should always be an open clear dialogue with your preceptor. When starting there should be a moment where the preceptor and the new nurse sit down and discuss what your expectations and they expect from you. When I was a new nurse my motto was this and still is, " I am licensed by the state not the hospital that hired me." When you have exhausted all your avenues to seek resolution, resign. You have your license and a clear conscious you did your best. You are giving great advice. Nursing should not be harmful to your psyche!!!!!!!!!
