What is a certified nursing assistant?
A certified nursing assistant (CNA) is a healthcare worker trained and certified to provide basic patient care tasks such as bathing, toileting, and vital signs monitoring under the supervision of licensed nurses.
the team nursing assistants form the frontline caregiving workforce in senior living communities. They perform hands-on tasks including bathing, grooming, toileting, mobility assistance, and taking vital signs like blood pressure and temperature. To earn certification, candidates complete a state-approved training program (typically 75 to 150 hours) covering patient hygiene, safety, communication, and basic medical terminology, then pass a written and practical competency exam administered by the state.
In the assisted living and skilled nursing context, CNAs operate under the direct or indirect supervision of licensed nurses-registered nurses (RNs) and licensed practical nurses (LPNs). Unlike personal care assistants (PCAs), who work primarily in home care settings and often lack formal certification requirements, CNAs must meet uniform state standards and pass an official exam. Unlike RNs and LPNs, CNAs cannot perform skilled nursing tasks such as medication administration, wound care, or IV management. The CNA role bridges direct resident contact and clinical oversight, making communication with nursing staff essential to flag changes in a resident's condition or needs.
