i work as a nurse tech in a hosipital here in new mexico. as far as i know to work as a nurse tech you have to have your cna-as well as hospital training as a tech. through the hospital training you learn to insert foleys, ng tubes, give enemas, wound care, discontinue but not start iv's (er techs start iv's and they must have their current emt license). also included is am care, ambulation of patients, vital signs, and basic patient care. assessments and medications are the responsibilities of the rn or lpn. nurse techs are there as a support for the licensed nurse. although, we are supervised during training performing certain things such as ng tubes, or foleys. i work on a med/surg unit where there is opportunity for alot of experience. good luck on your job, its the next step to your goals!
