What Is a Nurse Assistant
A nurse assistant, also called a certified nursing assistant or CNA, provides basic patient care under the supervision of registered nurses and licensed practical nurses. Their core duties include helping patients with bathing, dressing, feeding, and mobility, measuring vital signs such as blood pressure and temperature, and reporting changes in patient condition to the nursing team. The Bureau of Labor Statistics lists nurse assistants under the broader occupation of nursing assistants and orderlies, with a median annual wage reported in the latest available occupational employment statistics, and the role is classified within the healthcare support sector. For a detailed occupational outlook, see the Bureau of Labor Statistics occupational handbook page for nursing assistants.
Employers typically require a high school diploma or equivalent and completion of a state-approved training program that includes both classroom instruction and supervised clinical practice. After completing the program, candidates must pass a competency exam to earn state certification or listing on the state nurse aide registry. Some states impose additional requirements such as background checks, immunization records, and continuing education hours to maintain active status. The role is distinct from that of a licensed practical nurse or registered nurse, and nurse assistants generally work under direct supervision in settings such as hospitals, nursing care facilities, assisted living communities, and home health agencies.
Nurse Assistant Duties and Work Environment
Daily tasks for a nurse assistant include assisting patients with personal hygiene, helping them move between beds and wheelchairs, serving meals and assisting with eating, making beds, and monitoring and recording patients' intake and output. In hospital settings, nurse assistants may also help with basic clinical procedures such as taking blood pressure, pulse, and temperature, and they often serve as the first point of contact for patients, which makes communication and observation skills essential. The work can be physically demanding, requiring frequent lifting, standing, and walking, and nurse assistants must follow strict infection control and safety protocols to protect both themselves and patients.
The work environment for nurse assistants varies widely, with many employed full time in nursing care facilities, while others work in hospitals, home health services, or assisted living facilities. According to industry data, the largest employers of nursing assistants include nursing care facilities, hospitals, and continuing care retirement communities, and the job often involves shift work including nights, weekends, and holidays.

Certification, Career Path, and Related Roles
To become a certified nurse assistant, candidates must complete a state-approved education program and pass a competency evaluation. Programs are often offered by community colleges, vocational schools, and healthcare training centers, and they typically cover basic nursing skills, infection control, safety procedures, and communication with patients and families. After earning certification, nurse assistants can pursue additional credentials such as medication aide or phlebotomy technician to expand their scope of practice and increase their marketability.
Experienced nurse assistants may advance into roles such as licensed practical nurse, registered nurse, or healthcare supervisor by pursuing further education and licensure. The career path often starts with on-the-job experience that builds clinical skills and patient care competencies, and many healthcare systems offer tuition assistance or scholarship programs to support nurse assistants who wish to advance.
