Start

A certified nursing assistant (CNA) provides direct, hands-on care to patients and residents under the supervision of registered nurses and licensed practical nurses. The core of the job is helping people with the basics of daily life: bathing, dressing, eating, and moving safely. A CNA also tracks each patient's condition and reports any change to the nursing team. CNAs work in nursing homes, hospitals, assisted living communities, and home health, and the exact mix of tasks shifts with the setting. The work is physical and personal, and for many people it is the first hands-on role they take in healthcare. The day-to-day duties stay consistent, but the setting shapes the pace, and the role carries clear limits on what a CNA can and cannot do.

What Does a CNA Do?

A CNA provides basic care and helps patients with the activities of daily living they cannot manage on their own. Working under a nurse's direction, a certified nursing assistant typically handles the following:

Bathing, dressing, grooming, and toileting, including incontinence care
Turning, repositioning, and transferring patients between beds and wheelchairs
Taking vital signs, such as blood pressure and temperature, and recording them
Serving meals, helping patients eat, and tracking food and fluid intake
Listening to patients' concerns and reporting any change in condition to the nursing staff
Keeping rooms clean, changing linens, and following infection-control steps

Because CNAs spend more time at the bedside than almost anyone else on the care team, they are often the first to notice a problem, a new bruise, a drop in appetite, a patient who seems confused, and the first to flag it to a nurse. For the broader definition and history of the role, see what a CNA is.

How a CNA's Day Actually Looks

No two shifts are identical, but the rhythm is familiar. A shift often opens with rounds: taking vital signs and helping patients wake, wash, and dress. Meals bring another round of hands-on help, feeding those who cannot feed themselves and noting who ate and who did not. Through the day, CNAs reposition patients every couple of hours to prevent pressure sores, answer call lights, walk people to the bathroom, and chart what they observe.

The physical load is real. CNAs are on their feet for most of a shift and do a great deal of lifting and transferring, and nursing assistants have one of the highest injury rates of any occupation. The closeness that builds trust with patients also means being present for hard days, so the emotional side weighs as much as the physical one. Knowing the work is demanding before you start is part of deciding whether it fits.

Where CNAs Work, and How the Job Changes by Setting

Most CNAs work in one of a few settings, and the daily routine looks different in each. According to the BLS, about 35% of nursing assistants work in skilled nursing and residential care facilities and another 33% in hospitals, with the rest spread across assisted living, home health, and government facilities.

Nursing homes and skilled nursing facilities: CNAs are the principal caregivers and often build long-term relationships with residents they see every day. The pace is steady, the caseload is high, and the focus is on daily living and dignity.
Hospitals: the work is faster and more acute. CNAs support nurses with vital signs, mobility, and turning, and patients cycle through quickly rather than staying for months.
Assisted living: residents are generally more independent, so the role leans toward help with specific tasks and monitoring rather than total care.
Home health: a CNA cares for one client at a time in their home, which means more one-on-one focus and more independence on the job.

This is where the question gets its most honest answer: the duties are similar everywhere, but the setting decides the pace, the caseload, and how well you come to know the people you care for.

If the work sounds like a fit, you can look through CNA programs on Dreambound to get a feel for timelines and costs before committing to anything.

What a CNA Cannot Do

Just as important as the duties are the limits. A CNA's scope is set by state rules and nurse supervision, and a few tasks generally fall outside it:

Giving medications. In most states a CNA cannot administer medications without an added medication aide credential.
Drawing blood. Venipuncture is usually handled by phlebotomists or nurses, though some states allow a CNA to perform a delegated fingerstick glucose check after facility training.
Clinical procedures. Starting IVs, giving injections, and sterile procedures are nursing tasks, not CNA tasks.
Clinical judgment. CNAs observe and report, but diagnosing, building care plans, and changing treatment belong to nurses and physicians.

These limits are not a ceiling. CNAs who want to do more often move up to LPN or RN roles or add a credential that widens what they are allowed to do.

How to Become a CNA

Becoming a CNA takes three steps in every state: complete a state-approved training program of at least 75 hours, pass a two-part competency exam, and get listed on your state's nurse aide registry. Most people finish in four to 12 weeks. For the full walkthrough of training, the exam, and costs, see how to become a CNA.

CNA Salary and Job Outlook

Nursing assistants earned a median of about $42,260 a year, or $20.32 an hour, as of May 2025. Entry-level pay starts near $33,946, and government facilities and hospitals generally sit at the higher end of the range.

Job security is the stronger story. The BLS projects only about 2% growth for nursing assistants from 2024 to 2034, yet roughly 211,800 openings are expected each year, because turnover, not new positions, drives most of the hiring.

Frequently Asked Questions

Can CNAs draw blood?

In most settings, no. Drawing blood through venipuncture is generally outside a CNA's scope and is handled by phlebotomists or nurses. Some states do allow a CNA to perform a delegated fingerstick blood glucose check after facility training, so the exact rule depends on your state's nurse aide registry.

What is the difference between a CNA and a nursing assistant?

A certified nursing assistant has completed a state-approved training program and passed a competency exam, which places them on the state's nurse aide registry. "Nursing assistant" is the broader job title, and titles vary by state. The certified credential is what most employers and nursing homes require.

What is the hardest part of being a CNA?

Most CNAs point to the physical and emotional demands. The role keeps you on your feet for most of a shift, with lifting and repositioning, and nursing assistants have one of the highest injury rates of any occupation. The emotional weight of caring for people who are sick, frightened, or near the end of life is just as real.

What comes after CNA?

Many CNAs use the role as a first step. Common moves include earning a medication aide credential, training as an LPN or RN for more clinical responsibility and higher pay, or shifting into a related role like medical assistant or phlebotomy. The bedside hours you log as a CNA count toward most of those paths.

Building a Career From the CNA Role

The CNA role is hands-on care at its most direct: keeping people clean, fed, safe, and heard while serving as the eyes and ears the nursing team depends on. The work is demanding, and it is also one of the shortest paths into a healthcare career, which is why so many nurses, medical assistants, and technicians started here.

Knowing exactly what the day asks of you is the best way to decide whether it fits. When you are ready to compare CNA programs by length, schedule, and price, Dreambound lays the options out side by side so you can choose the one that matches your plan.
