As you are aware, the scope of practice for Nurse Practitioners differs from state to state, and sometimes even organization to organization, so it is important for you to know and understand the independence you will have in this particular job and be able to explain that to your interviewer. Whether your experience in the state enables you to talk openly about your scope of practice or you need to research further before the interview, talk about your understanding of the procedures and actions that you will be permitted to do in this role and which procedures and actions will require physician supervision. Don't hesitate to talk about your past experiences in working under this same scope of practice.
