Been there, done that.
I got my ADN in 2003. Took a break and found a program that I ABSOLUTELY LOVED! Smartest program and organization of curricula I have ever encountered. Texas Tech University, Health Sciences Center RN-BSN program (http://www.ttuhsc.edu)
. Less prereqs required than some others I looked at, too. Anyway, it took a straight 2 semesters, was 100% online except for the few clinicals that you set up in your home area. It is geared for full-time working students. They stagger their courses so that you are only concentrating on 2-3 at any given time. Its like, one class lasts the entire semester, and the others are only 4-5 wks long. ITS GREAT! EVERYBODY worked while doing it. Teachers great! Only 2 day on campus requirement for orientation. Not sure where you are... but it was definitely a GREAT choice for me if you do decide to do your ADN first.
Now I am in an NP program that, at a full time pace, will take me about 18 months - VERY fast.
Benefits to doing ADN first in your situation... you get to work faster... can get on with your life to some degree (pay off bills, new vehicle, etc.)... find your niche in nursing, etc. Me personally, without my working experience to kind of point me in the right direction of what area of nursing I wanted to do as an NP, I would have probably gone a completely different route with the MSN/NP and been completely disappointed! I believe 100% in overachieving... welcome to my world! LOL... but, take it a little slow. Nursing is a great career choice and I love it, but just because you have something set in your head right now... it may change. I'd just hate for you to get into some rush to get your NP without having enough time to figure out what makes you the happiest and gives you the most satisfaction... does that make sense?
And yes, there are RN-MSN programs out there. Most of them are MSN-Education stuff, but I think there are NP ones, too. I know that TTU has one of those too.
BEST WISHES!! And don't hesitate to PM me!
