It really depends on what you need your education to be. It also depends on the time you have to complete the degree, the financial resources, etc..
For me, the ADN is the only route I could take right now. Money, distance to get to school, etc...all factored in to my decision. I am also a non traditional student who already has 1 BS degree. I have a job, husband and a child...oh and also a business to run. I had to factor my WHOLE life into my decision. The ADN was the best possible thing for ME.
I had to take what I needed out of my degree and figure out the best possible way to get there. For me, it was the ADN degree. For others it will be the BSN degree and even for others, it will be going on for even further advanced degrees.
The best advice I can give you is to research all the possible ideas, schools
, etc...and find which one fits you and your needs.
