A certified nursing assistant, or CNA, may work in a hospital, a clinic, a nursing home or even in the patient's home. No matter the location, the duties of a CNA are about the same.They are there to provide safe and reliable care for those who need help or cannot care for themselves. Certified Nursing Assistant in a nursing home or hospital will also tidy up the patient's room. A custodial staff member usually does the deeper cleaning, but the CNA will do some light cleaning if it's needed. Making beds and putting away laundry are two responsibilities that often fall on the CNA.
CNAs also serve as a conduit between patients and nurses and doctors and record and communicate all issues to medical staff. Depending on where a CNA works, other duties might include transporting patients to operating rooms or treatment units and setting up equipment at a nurse or doctorâs request.
