Physician assistants help physicians provide medical care to patients. PAs may be assigned a variety of tasks; they may take medical histories of patients, do complete routine physical examinations, order laboratory tests, draw blood samples, give injections, decide on diagnoses, choose treatments, and assist in surgery. Although the duties of PAs vary by state, they always work under the supervision and direction of a licensed physician. The extent of the PA's duties depends on the specific laws of the state and the practices of the supervising physician, as well as the experience and abilities of the PA. PAs work in a variety of health care settings, including hospitals, clinics, physician's offices, and federal, state, and local agencies.
