Be advised, that there is NO OFFICIALLY RECOGNIZED TITLE OF NURSE TECH by the medical governing bodies. Nurse tech is usually a designation given to those who may not (or may) have official certifications involving some level of health care education. E.g. someone in a Nursing program
who has received an education equivalent to or surpassing that of a CNA may be allowed to work as an N.T. Same may be said for those in training for EMT/Paramedic, etc.
The "scope of practice" however, varies from facility to facility. Depending on your training, where you are in your program, the type of program, etc...these factors may determine your duties. PLEASE have your Job Description fully outlined before taking the position...and if your position evolves to include more or advanced procedures, have the j.d. amended to included those duties. Protect yourself, as you are a future potential license holder. You never want it to be said that you did something beyond your scope/j.d.
I know when I was a N.T., I got to do many things that were NOT on my official list of duties...even though I did those things everyday in clinicals. However, on the job, I was not acting as a student nurse, therefore, even as I did the advanced things I wasn't even "protected" under my supervising RN's license. Those RNs were friends of mine, knew my level of competence and so they allowed me that freedom.
However, since I've been licensed, I dare say that I would NOT do the same thing for a friend who was a NT under my supervision. I don't want to take that risk for ANYONE...not another licensed nurse nor unlicensed person.
