As health care assistants, you are expected to perform a variety of patient care and administrative duties. Some of the responsibilities expected to cover include interviewing patients, assist with patient exams, record data, maintain exam room equipment, and help patients with hygiene needs, serve meals, and check vital signs. 

In the dental field, you are required to sterilize equipment, take x-rays, and make casts of teeth. If you are a health care assistant with nursing assistant certifications, you can become home-care aides to provide health-related services to homebound patients. You may find yourself working in fields ranging from physical therapy and mental health, to cardiology and nursing.
