I think an ADN would be sufficient for you. There are a lot of misconceptions about ADN vs. BSN related to advancement. It's all about how you sell yourself. Both my assistant nurse manager and nurse manager have only an ADN. There are many possibilities for you and any hospital that hires you could utilize your prior knowledge to their advantage for things such as diabetes teaching and dietary teaching related to medications. Good Luck.

Nursing education
You may not need a BSN for advancement in certain areas of nursing but it certainly wont hurt! The important question is... what area of nursing are you interested in? Some will prefer a BSN to start. Some BSN programs will give you advanced placement status if you already hold another degree. Have you thought about an accelerated MSN? You would be a great candidate for one of the accelerated programs. There are many choices for nursing education, especially since you already hold a degree. So look at all of your options before making a choice. Good Luck!

this biggest misconception about adn/bsn comes from bsn instructors selling it to their students why they need the extra 2 years of college. it is not necessary at all. i can tell you of atleast 15 nurse managers of the 17 hospitals i have worked at they were all adn's other 2 were msn's
its all up to you and your work ethic on what you become. my brother is an lpn and was an adminsitrator.
