Hey guys it is me again. Me with the many questions. I love reading your discussions and learning more and more everyday. You have answered all of my questions and I am hoping you will again.
After reading some of your horror stories about nursing, I am not sure if this is something I want to do or not. I mean I have worked in the doctor's office and had to clean up everything imaginable. I handled it quite well. Blood, feces, vomit does not seem to bother me. Maybe my problem is I am just scared. Is that it?
I know I do not want to go into Radiology. Cadiovascular does not have alot of job openings here. There is a ton of jobs for RN.
Can anybody help me. Like I said is it just NERVES? I have done gone thru two years of school in 2000 for MA. Surely I can do it again....
I am excitied about starting school the 26th...
