Edited to say: The NP (nurse practitioner) route is essentially as long as the MD route because new requirements involve getting a PhD. The upside is you would be able to work as an RN while pursuing further study. Also, many states require a master's degree for PAs, and that is two years minimum on top of undergraduate study. The fastest way to get out there and working is the nursing route, but you could also work in support positions as you go through undergraduate study for any of these options.
I don't think you are including the rigorous residency programs and processes for board certification that the physician route requires compared with NP. The new requirements for
DNP are still not as rigorous as the MD and DO route. And there have been plenty of doctorate programs for nurses for many, many years, decades now. The DNP is what is new.
The difference is the approach/focus.
Also, there have been quite a number of programs that require/required the same General Bio and Gen Chem that most pre-meds take. In fact, in a number of programs they are prereqs for the Microbiology and the A&Ps.
The big difference is the Organic Chems and Physics requirements--also Calc and Biochem if the particular meds schools required those as prereqs. In either program, math courses like Statistics are still required.
And of course some programs have their own honing-like Biological or Chem courses for nursing--bypassing some of the non-human biology and chemistry stuff. So, it depends on the program.
CRNA programs are tough to get into b/c there are only so many seats. You are required to have a BSN first and usually at least a year in critical care nursing--to me, ICU at high level centers is better, but nowadays they are allowing nurses to have a year of ED--even though ICU at high acuity centers, to me, is a lot more specific and relevant to anesthesia.
The CRNA programs have moved to Masters and are moving to doctorates as part of the
completion. It's an intensive 2.7 to 3 years in such programs and will have to become longer to meet the desire for doctorate requirements. Is it as intensive as medical
school then residency? Not necessarily. But I do think the poster meant to write CNA. CNA
courses nowadays are more focused on homecare, so you might want to consider a care tech role in the hospital.
Not a lot of CCU nurses are making six figures, unless they are working OT or work in certain areas of California or work some contract/agency jobs.
Average salaries for RNs are between I'd say $50,000 to mid $70's across the country, the higher end being w/ a lot of experience.
