What Sour Lemon said. You may also want to try working as a CNA for a bit to see if you'd like nursing, get a feel for it, etc. I don't see where having a degree outside nursing would hurt. But as mentioned already, call up some schools, talk to a guidence counselor and see what might be a good fit for you. No, you don't have to work as a CNA to get into nursing or nursing school. I just (my opinion) think it is helpful.
