A Certified Nursing Assistant is a member of the health care team. Always working under the direction of a nurse (RN or LPN/LVN) the CNA provides hands on nursing care to patients, residents, clients and customers in a variety of health care settings.
To be a CNA (Certified Nursing Assistant), you need to be 18 (usually due to liability) and have taken a CNA course (usually lasts anywhere from 4 weeks to a few months; depending on the frequency of the class each week).
