Medical assistants play an important role in physicians' offices and clinics by handling both administrative and clinical duties. They are trained to take patient vital signs, medical histories, assist with examinations, perform lab tests, administer medications and injections, and instruct patients on self-care. Medical assisting is a one-to-two year program available at community colleges and accredited institutions, and includes coursework in anatomy, medical terminology, administrative skills, and a required internship. Employment opportunities are excellent and expected to grow rapidly in settings like physicians' offices, hospitals, and specialty practices.
