CNA Training, specifically certified nurse’s aide training, prepares those who undergo it to work in a variety of health service venues, either with short-term stay patients or long-term stay residents. These venues can be hospitals, for example, rehab centers, or nursing homes.
In the superstructure of health care it is the doctor who diagnoses and prescribes. Meanwhile, at the next level, it is the nurse working at a long or short-term stay health care facility whose job it is to deliver the treatments and drugs the doctor has prescribed to the resident or patient, as well as document the progress of the patients or residents in his or her care. Those with CNA training work under the supervision of a nurse, delivering hands on care. Often, it is the CNAs, acting in their capacity, who serve as an invaluable extra set of eyes and ears for the nurse.
Because they are often the first caregiver the resident or patient calls on, as well as the caregiver who usually spends the most one on one time with the patient or resident, it is often the CNA who first notices important changes in those they care for. These changes in the patient or resident’s catalog of symptoms are very important, as they affect both the ongoing care of the resident or patient as well as the documentation the nurse must maintain. Aside from making use of their eyes, their ears, and their training, which alerts them what to look for, CNAs also collect official data using various health care implements. They do this by taking, blood pressures, temperatures and other kinds of measurements, useful for documenting a resident or patient’s progress or decline.

While the doctor has the training to read and interpret specialized tests and criteria, thereby making an informed diagnosis, he or she is not generally available to witness each patient or resident’s ongoing reaction to treatment over each twenty-four hour period. He or she must rely on the detailed written observations of the nursing staff. While the documentation done by CNAs is generally of a more mundane nature, their notes and observations are crucial to fleshing out the reports and documentation of the nurses who deliver the drugs and treatments and in turn report changes of import to the doctor. Clearly then, it is obvious that those with CNA training fill an invaluable capacity in the health care industry.
