I agree with Crux1024, I was a little torn about what I wanted to do when I was first filling out college apps and then I shadowed my aunt who is an RN and just knew that that was what I wanted to do. It helps to be exposed to the different fields so you can really get a feel for what they are all about! You will definitely have to deal with many bodily fluids and bad smells though! That is basically a means of weeding people out of the nursing program (at my school anyway). I wasn't necessarily ever squeamish with that kind of stuff, but I'll admit I was grossed out by certain things...however, being around it all the time and being forced to deal with it in clinicals helps you get over that very quickly! Nursing is a tough major and profession, but I find it to be very rewarding and at the end of the day, very worth it. I hope this helped a bit, good luck with your decision! :)
