hello, I would like to know if any one has any advice for me. I am considering a career change from criminal justic to nursing. I have finished all my prerequisites and even completed my CNA, but I am scared to continue with nursing. I know nothing about meds and or the medical field and this makes me so nervous, I feel like i would not get past nursing school. I am considering, respiratory school because I feel this would be easier school wise. When I was doing my CNA I really wanted to see what a nurse does, but I did not get a chance to. Can some one tell me what a typical day for the nurse is like, specifically the duities? I tried to call a local hospital and ask to shadow but i was not allowed due to patient confidentiality.
