Can you be hired as a "pre-RN" until you pass your NCLEX?
Ive seen "Nurses" hired to the Hospital I work at who are "GN"s (Graduate Nurses) instead of RNs. They have graduated from Nursing school but havent taken the NCLEX. Im not sure if or how their scope differs from RN as they were going through orientation while still a GN. They may just keep them on orientation until they pass the NCLEX, or I suppose if they fail in which case theyd probably be fired or asked to quit.
I think Nurse Techs are different from PCTs in that they can do more.
As for the difference between PCT and CNA, I think it varies depending on the hospital. In some cases it might just be different titles for the same job, but usually a PCT does blood draws, inserts foleys, and performs 12 leads, which are things CNA school doesnt cover, at least the one I went to.
