What is a Certified Nursing Assistant?

Healthcare career overview, clinical scope of practice, and professional expectations

A Certified Nursing Assistant (CNA) is a vital frontline healthcare professional who works directly with patients and residents to provide essential daily care, monitoring, and emotional support. Operating under the direct supervision of Registered Nurses (RNs) and Licensed Practical Nurses (LPNs), CNAs serve as the primary observational eyes and ears of the healthcare team. CNAs assist individuals who are ill, recovering from surgery, or experiencing aging-related cognitive or physical decline with everyday activities—such as bathing, dressing, eating, ambulating, and maintaining personal hygiene. Because CNAs spend more one-on-one time with individuals than almost any other healthcare staff member, their prompt recognition of vital sign changes, skin breakdown, or mood shifts often prevents critical complications.

Frequently Asked Questions (FAQ)

Authoritative answers on Certified Nursing Assistant state testing, passing scores, and examination rules

What does a Certified Nursing Assistant (CNA) do?
A CNA provides hands-on direct care to patients and residents in hospitals, nursing homes, assisted living facilities, and home healthcare settings. Duties include assisting with daily living activities (bathing, grooming, meals), measuring vital signs, repositioning residents to prevent pressure injuries, and reporting health changes to nurses.
What is the structure of the CNA Certification Exam?
The CNA exam consists of two independent parts: 1) A Written (or Oral) Knowledge Test typically featuring 60 to 70 multiple-choice questions completed on a computer within 90 minutes, and 2) A Hands-on Clinical Skills Evaluation where you perform 5 randomly assigned skills in front of an RN evaluator.
What are the critical safety steps on the CNA Skills Test?
Critical safety steps are non-negotiable procedural elements that must be performed 100% correctly to pass a skill. Examples include washing hands thoroughly before and after contact, locking bed and wheelchair brakes before transferring, pulling privacy curtains, and placing the call light within reach.
Do I need a high school diploma or prior medical experience to become a CNA?
In most jurisdictions, a high school diploma or GED is recommended but not strictly required by all state registries to begin state-approved training. No prior medical experience is necessary—approved training programs teach all required basic anatomy, care procedures, and infection control.
