Duties of a Certified Nursing Assistant (CNA)

Certified Nursing Assistants (CNA) are a group of people who assist the nursing staff with patients' care and needs. The duties of a CNA are often dependent upon the work setting that the assistant is in.
Certified Nursing Assistants (CNA) are non-technical staff of a hospital, nursing home or a day care center. The CNAs, at times, work for patients in their homes too. They are also called orderlies, nurses aides, patient care technicians or home health aides. They provide basic nursing care under the direct supervision of Licensed Practical Nurses or Registered Nurses. In other words, they perform non-professional tasks and help the technical staff. Being a CNA can be considered as a stepping stone to make a career in the health care industry. To become a CNA, a course can be pursued at various universities, colleges and nursing schools.

Certified Nursing assistants are called 'eyes and ears' of the nursing staff as they carry out a wide range of tasks which, in turn, help in keeping hospitals and health care centers working at the optimum level. They inform the nurses about the vital information of patients from time to time. They are, more often than not, the primary caretakers of many hundreds of recovering, aging and terminal patients. Many times they forge an unending bond with the patients and their relatives, as they spend maximum time with the patients.

I think the elderly take a caregiver for more than who they are and their duties.
Some elderly expect and ask more than they should.
Caregivers are underpaid and most of the time are considered like a slave... with a little bit or less respect or with no respect at all from most of the elderly.
I think something needs to be done regarding a caregiver salary and treatment.

As a Register Nurse I find this job description for LNA's a bit misleading regarding the following: Administering Medicines: Administering medicine is one of the important duties of a CNA.

LNA do NOT administer medications. LMNA can administer SOME medications under the direct supervision of a nurse. The LMNA course is offered to LNA's and is monitored by the state is which the LNA/LMNA is licensed to practice in.
