What exactly does a CNA Do?

Pulled from a Google search (allnursingschools.com):

A certified nursing assistant's (CNA) main role is to provide basic care to patients, as well as assist them in daily activities they might have trouble with on their own, such as bathing. Because of the personal nature of the job, certified nursing assistants should be compassionate and enjoy helping others.

In many cases a CNA preforms almost identical functions to a registered nurse (RN) although they're usually delegated the non-medical aspects of patient care like grooming, bathing, feeding, bed changing, and checking vital signs. Depending on the state/hospital they may also administer medication, draw blood, give shots, and sample fluids. Of the medical professions they tend to have the most direct interactions with patients and are expected to alert their superior (usually an RN or LPN) of any changes in the patient's condition. Unlike RNs they usually cannot alter a medical plan of care without a supervisor's permission.

My daughter is in the nursing field and will graduate as a RN in December. She has been a CNA since she was 16. You are dealing with patients directly in their hygene care and assisting with needs they have. So bathing, restroom, changing diapers. And some areas are as simple as helping with their laundty, cooking meals, feeding them etc.
