The opposite can happen too — nurse practitioner immediately demanding unnecessary biopsy or other tests because they cannot confidently rule something out. This happened to me recently when I went to a np for a known problem I have had for years that was already diagnosed by multiple doctors. I also find np is much more likely to prescribe antibiotics. Of course this is all anecdotal. I used to be very much in favor of expanding the scope of what nurses can do but now I feel like that may do more harm than good.
