I am a relatively new Fnp and with both jobs I took, I made it very clear that I expected some support and backup. Yes, you are prepared for your field and with clinic hours, but it's not ok to guess at what your patients need. Your employer will not know or care what you need, so you need to be very clear. I work in Peds neuro now, very non-standard for an Fnp prepared nurse, (though I have years of Peds RN experience, not the same) but I have excellent support from my team. I also added slowly to my patient panel. Let the fear factor guide what you find acceptable in a job and don't be railroaded into going beyond your comfort level.
