Here are some things you should consider:
1. Look at the schools
within your region first. It's an advantage to be within driving distance of the school so that you could visit the campus easily if you wanted to. While you may never want an on-campus visit, sometimes it's nice to be able to go talk to a professor face-to-face, get together with classmates with whom you are working on a project, or spend an afternoon in the actual library gathering resources (with the help of a librarian) for your big project. So check out if there is a suitable school within reasonable driving distance.
2. Check out schools within your state first. They will probably be cheaper. You have been paying taxes to support the schools in your state. Now is the time to take advantage of the lower rates for "in-state" tuition.
3. Ask nurses you know where they went. It can be helpful to have some upper-classmen to talk to -- who have already taken those particular classes with those particular teachers.
In sum: An in-state school within reasonable driving distance is often your best bet, particularly if you know someone who has already gone there. Such a school might not be the perfect school, but it is often the most practical school to attend. Don't overlook such schools as you look nationwide.
