I am in a very similar situation (BA in Journalism, making a career change to nursing). The accelerated BSN programs are designed for people that already have a BA/BS in another field, or for very serious undergrads, and having a work history in any field will give you an advantage and maturity. For 9 out of 10 programs, you will need to take several pre-req's that you did not take in undergrad (chem and organic chem, anatomy and physiology, pharmacology, developmental psych, and some other very nursing-specific classes). The exception to this rule (the 1 in 10 school!) is that there are some schools
(for example Chamberlain college of nursing), usually for-profit schools, that do not require any course work to be completed prior to acceptance into the RN program- they give you everything. The downside is that these programs are cost prohibitive (think 80K).
While you are taking pre-reqs, work away! And save as much money as possible! The accelerated BSN programs are, as someone already mentioned, more than a FT job and you will be attending classes during the AM and clinicals in the afternoon/PM/overnight. You will really not have time to work. The accelerated BSN programs are only a 12-15 months, so you are compressing a 2-3 year education into that short amount of time... leaving very little time for a job.
That being said, you may be able to work a job with flexible hours (like serving or tutoring), but a regular 9-5 is almost out of the question. I hope this doesn't discourage you! I am going through the same thing right now - completing my pre-reqs and starting to choose an accelerated program on the west coast.
Best of luck!
