I wouldn't worry about finishing the liberal arts degree...BA's don't have hardly any sciences, math, etc...and it leaves you taking a TON more courses in the end.
It looks like you live in a heavily populated area. Something to ask yourself, if your son has major medical issues, and you have to be nearby, is nursing school
at this time even a practical option? Obviously, you have to make that decision for yourself and your family. It's just something to think about.
I would apply to as many schools
as possible, let the chips fall where they may, and then work out the demographics later.
I would also get one of the mods to move your thread to your state, you would probably get more responses there.
