Dread, the person with the badge on was probably not a nurse. Nurses train from 2 to 4 years and have a college level degree. Although they certainly have the skill to take a blood sample, they are not usually the one to do so. A phlebotomist is a high school grad, or, GED off the street. They attend a short course on phlemotomy, and, that's it. They have no additional medical training or knowledge. One of the confusing things in modern medical facilities is that everyone wears "scrubs". Time was when you could immediately recognize a nurse, or doctor by their dress/uniform. Now, everyone dresses alike. Heck, for all you know the janitor, dressed in scrubs, was taking your blood sample.
