I have a friend who finished her first semester of an ADN program and she realized that she preferred being an Occupational therapist over an RN. She is qualified to take the CNA test since she finished her Fundamental of Nursing class. Her plan is to get some rehab experience before applying for an OT program from working as a rehab nurse tech. My question is is a CNA the same as a rehab nurse tech? Or is rehab nurse tech a whole different field from being a CNA?
