Does anybody know any southern HBCU's that offer a Bachelors of Nursing (undergraduate.)?

Several HBCU's offer nursing. You can go to http://www.college-scholarships.com/ and click on HBCU's on the right margin navigation bar. From there you can visit HBCU websites and find contact information to request information from each.

Without bashing all HBCU's, there are a number of them that are currently really struggling, and many of these don't graduate more than half of their students. Make sure, when looking at potential schools, that you look for some statistics on what percentage of their students graduate, as that number can indicate how well you may do at that school. I know no one thinks they are going to drop out when they head off to college, but a lot of students do, and a good school makes sure they have a support system to prevent this from happening.

Here is a link to a listing of schools, their location, enrollment, and tuition--
