If the costs and time for getting your BSN (or an entry-level master's degree) is only slightly more than the ADN, then get the higher degree in the beginning. You'll probably want it later -- and going back to school yet again will be stressful for you and your family. However, if the difference in costs (and time) is enormous and the ADN is readily available, then starting your nursing career with an ADN makes sense.
The entry level nursing jobs are the same regardless of what type of degree you get first. However, there are a lot more opportunities out there (and not just in management) for people with BSN's and above. In the long run, you will probably be interested in those opportunities. So, you'll want that BSN or Master's Degree. If it's possible to get it from the start, it's the best way to go. Since you already have a BA, the difference may only be a couple of classes. However, if the specific requirements of your local programs make the BSN much longer, harder, and/or more expensive at this point ... the ADN option is OK, too. You can get your BSN later and those BA courses should count towards your BSN completion program.
As other posters have said, the "best" choice for you really depends upon the specific requirements, costs, and availability of the programs in your local area. Investigate each program carefully and see what the specifics of those programs actually are.
