Debbie, the prereqs thing is usually more of a concern for an adult returning to a two- year program.
Did you take bio, chem, physics, and some higher math in HS? If you did, and your grades are high, you should not have a problem being accepted into a nursing program. If you can afford it, go straight for your BSN.
And find your school's guidance counselor - if she's not useless she'll have ways to help.
And good luck.
