This is an interesting topic. I worked as a CNA for 9 months; nurses wore different scrubs (style and color) than CNA's. I always introduced myself as the Certified Nursing Assistant. Because I am older and educated (I'm a retired teacher with a BA and an MA) many, many patients "thought" I was a nurse. This happened almost daily! I don't know if it was because I was professional in my job, the way I talked, looked or whatever???
