Tennessee regulates medical assistants by requiring them to be certified to work in certain medical settings. In an "ambulatory outpatient hospital clinic," owned by a hospital that treats patients who don't stay overnight, certified medical assistants are trained to assist doctors and nurses. They must be certified by an approved organization. These assistants can administer standardized vaccines but only give other medications if directed by a doctor or nurse. This regulation does not apply to medical assistants outside these clinics.
