hi, I'm a 20-year-old junior biology major & all my life I was sure I wanted to be a doctor until I realized that it may not be the lifestyle for me. I have recently begun looking into advanced BSN programs. My school does not have a nursing program so I cant switch my major I'm kind of stuck with biology, I am already 60 + credits in so it is what it is. Now I know there are sooooooooooooo many different types of nursing and nursing jobs and I wanted to know if you guys could help me understand them. So far with the help of youtube and google, i have come across CRNA, NP, DNP and of course RN's. I wanted to know if u guys could explain to me in detail all those positions and any others that I don't know about. Thanks in advance .
