I work in an office with an Internal medicine doctor. He recently hired a lady who says she is a medical assistant, but cannot produce a certificate. She claims that she has been doing this for so many years that she just became a medical assistant and was not required to have a certificate. Anyways, she was hired by the doctor I work for and he never did a background check. Since she has been hired, she does everything that the rest of the us nurses do, injections included. This bothers me. When I questioned the doc. about it, he basically said that He can train anyone to do anything he wants in his office as long as the are under his supervision. Does anyone know anything about this. Why would a doctor take a chance like this by not hiring a licesensed or regisitered nurse or a medical assistant? Also, aren't medical assistants certified in tennessee. I know that they do have a 6 month program here.
