A nurse assistant is a healthcare worker who provides basic, hands-on care to patients and helps them with everyday physical tasks they can’t manage on their own. Often called nursing aides or certified nursing assistants (CNAs), they are essential members of the healthcare team who work under the supervision of licensed practical nurses (LPNs) and registered nurses (RNs). While they don’t administer medications or perform complex clinical procedures, nurse assistants are frequently the staff members who spend the most direct time with patients.
What a Nurse Assistant Does Every Day
The core of a nurse assistant’s job revolves around helping patients with activities of daily living, commonly called ADLs. These are the basic physical tasks that healthy people do without thinking but that become difficult or impossible during illness, injury, or aging. They include bathing and grooming, getting dressed, eating, using the toilet, and moving from a bed to a chair or walking down a hallway. A nurse assistant might help a post-surgery patient get out of bed safely, assist someone with dementia during meals, or help a resident in a long-term care facility with personal hygiene.
Beyond direct physical care, nurse assistants play a critical monitoring role. Because they spend so much time with patients, they’re often the first to notice changes in someone’s condition, whether that’s increased confusion, difficulty walking, loss of appetite, or skin breakdown. When a patient’s ability to perform daily activities starts declining, the nurse assistant reports those observations to the nursing and medical team so the care plan can be adjusted. This communication function is just as important as the physical care itself.
Other common tasks include taking vital signs like blood pressure, temperature, and pulse, making beds, turning bedridden patients to prevent pressure sores, helping patients with range-of-motion exercises, and documenting intake and output of food and fluids.
Where Nurse Assistants Work
Nurse assistants work across nearly every healthcare setting. Skilled nursing facilities and long-term care homes employ large numbers of them, since residents in those settings need daily help with personal care over extended periods. Hospitals also rely on nurse assistants to support nurses on busy medical, surgical, and rehabilitation units. Home health care is another growing area, where a nurse assistant visits patients in their own homes to help with bathing, dressing, and other daily needs while monitoring for any health changes that need to be reported to the clinical team.
Assisted living communities, rehabilitation centers, and hospice programs round out the list of common workplaces.
What a Nurse Assistant Cannot Do
Nurse assistants operate within a more limited scope of practice than LPNs or RNs. They cannot administer medications, whether by mouth, injection, or IV. They don’t perform wound care, change surgical dressings, start IV lines, or carry out other complex nursing procedures. These tasks fall to LPNs and RNs, who have significantly more training. A nurse assistant’s role is to provide supportive, non-invasive care and to serve as the eyes and ears of the nursing team by staying close to the patient throughout the day.
Training and Certification Requirements
Federal law requires that nurse assistants working in Medicare- or Medicaid-certified nursing homes complete a state-approved training program. The Omnibus Budget Reconciliation Act of 1987 set the federal minimum at 75 hours of training, including at least 16 hours of supervised clinical practice. After completing the program, candidates must pass a competency evaluation to be placed on their state’s nurse aide registry.
In practice, most states require more training than the federal minimum. Thirty states and the District of Columbia have raised their required hours beyond 75, with some going much higher. Maine requires 180 hours, Missouri requires 175, and Oregon requires 155. California mandates 150 hours, with 100 of those spent in clinical training. On the other end, states like Alabama, Kentucky, and Ohio stick to the 75-hour federal floor with just 16 clinical hours. Thirteen states and D.C. now require at least 120 hours, which is the standard the National Academy of Medicine has recommended.
Training programs cover topics like infection control, patient safety, communication skills, nutrition basics, and proper techniques for lifting and repositioning patients. The clinical portion gives students supervised, hands-on experience providing care in an actual healthcare facility before they work independently.
Pay and Job Outlook
The median annual wage for nursing assistants was $39,530 as of May 2024, according to the Bureau of Labor Statistics. Pay varies by setting and region, with hospital-based positions generally paying more than long-term care facilities.
Employment growth for nursing assistants is projected at 2 percent from 2024 to 2034, which is slower than average for all occupations. However, this modest growth rate is somewhat misleading. Because the workforce is so large and turnover is high, tens of thousands of openings are expected each year as workers leave the field, retire, or move into other nursing roles. Many nurse assistants use the position as a stepping stone toward becoming an LPN or RN, creating a steady cycle of vacancies.
Why the Role Matters
Nurse assistants fill a gap that no other member of the healthcare team fully covers. Nurses and physicians focus on clinical decision-making, medication management, and treatment planning. Nurse assistants handle the continuous, labor-intensive work of keeping patients clean, comfortable, fed, and mobile. In settings like nursing homes, where residents may need help with every basic physical task, this role is the backbone of daily operations. The close, repeated contact nurse assistants have with patients also makes them uniquely positioned to catch early warning signs of complications, falls, infections, or cognitive decline before those problems escalate.
