I would recommend you to go ahead and get your STNA and work as a L&D tech while in nursing school. Most hospitals won't hire you until you are 18 though. L&D is a very competitive dept. to get into, so get in as a tech and make good connections. As for getting over vomit. It just gets easier with time. Remember, breathe through you mouth, the smell just makes it so much worse! OSU is a good school, it's very competetive. Check out the Ohio Board of Nursing website for different schools. I based my decision on NCLEX pass rates.
