You should look into an accelerated BSN program. This is for people who already have a bachelor's degree in another area, and they take anywhere from 12 - 18 months to complete, to get a Bachelors of Science in Nursing.
BUT, you can't get into the accelerated programs until you've first finished your pre-reqs, which include all the sciences - Biology, Microbiology, Chemistry, Sociology, Psychology, Lifespan, Nutrition, Statistics, etc. That often takes at least a year to do - full time, no working. Accelerated programs are very difficult to get into - there are long waiting lists and few seats available - and it's extremely competitive to be accepted. I did an accelerated program - 300 people applied for 30 spots. I barely made it in with a 3.9/4.0 in my science classes.
Once you get your BSN, you then spend your first year of nursing actually learning how to be a nurse. You'd be amazed at how little you learn about real nursing in nursing school
. It takes a long time to become competent and confident. There are so many variables, so many disease processes to memorize, so many drugs with different doses, side effects/reactions, so many signs/symptoms to become familiar with, etc.
Then to become a CRNA, it's an additional two years. To even be considered for a CRNA program, you have to have at least 2 years of ICU experience (at most schools
.) A lot of people think they instantly want to be a CNRA because you make good money, but they're not aware of the responsiblity involved - you're doing the same work as an Anesthesiologist, which is an MD. You need to be highly skilled - which truly is only gained through years of experience. School doesn't do that for you. It's really not feasible to instantly become a CRNA.
I would personally not feel comfortable applying for CRNA school until I had several years of experience as an RN. Most of our CRNA's at my hospital have at least 10 yrs nursing experience under their belt.
I had a former career in marketing, and it was cake compared to nursing. A 12-hr shift in nursing is like 24 hrs at a desk job. Nursing is incredibly hard academically, emotionally, physically, etc. You're expected to have an amazing level of knowledge and liability, but then also be able to clean up poop and deal with beligerent patients and their families.
I would research the requirements of accelerated programs near you, and most importantly try to shadow a nurse to see what you're really in for. Being a CRNA is an afterthought after becoming a nurse. Good luck to you.
