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 become an RN, some colleges require you to have taken the CNA course as a pre-requisite. So completing a CNA course can be very useful if you wish to progress to an RN. As an RN, you can then further specialise in any of the following fields: RN in Emergency Room, Family Nurse Practioner (NP), a Charge Nurse (RN) and an RN in Operation Room.
