CNA Scope of Practice: What You Can, Cannot, and Must Report

The CNA scope of practice covers hands-on personal care, help with activities of daily living, and basic clinical data collection performed under a licensed nurse’s delegation and supervision. It stops at anything that requires nursing judgment: administering medications, performing sterile procedures, assessing or diagnosing patients, writing or changing a care plan, and giving medical advice. Federal regulations set the floor, and each state’s Nurse Practice Act can tighten or loosen specific tasks on top of that baseline.¹

What You Can Do

Personal care is the largest part of the job. That means bathing, grooming and oral care, dressing, toileting, skin care, and helping residents eat and drink. Each task has technique attached to it. Bathing a bedbound patient is not the same as helping someone into a shower, and both demand attention to water temperature, privacy, and fall prevention.²

Transfers and positioning are the next big block. Moving a patient from bed to wheelchair, repositioning to prevent pressure injuries, and ambulating with a walker, cane, or gait belt all fall inside your scope, along with using mechanical lifts when the patient’s weight or mobility calls for one. Bad body mechanics create real consequences on both sides of the transfer: respiratory or circulation problems for the patient, back injuries for you.

Feeding is more than delivering a tray. Proper technique is a separate training requirement because aspiration is a live risk, especially with residents who have swallowing difficulties. You control the pace, watch for choking or coughing, and report any change to the nurse. Restorative work fits alongside this: helping residents practice self-care, maintaining range of motion, and using prosthetic or orthotic devices to keep as much independence as possible.

On the clinical side, you collect the numbers the care team uses to track a patient. That includes measuring and recording blood pressure, heart rate, temperature, and respiration, plus height and weight on schedule. Fluid intake and output tracking means measuring every liquid the patient takes in and the volume they put out, which helps catch dehydration, kidney trouble, or a urinary tract infection early. You also collect non-invasive specimens like urine or stool, following labeling and handling rules so the sample stays usable in the lab.

Post-mortem care usually falls to the nursing assistant once a licensed provider has pronounced the resident. You bathe soiled areas, position the body, close the eyes and mouth, apply a clean gown, and prepare the room for family viewing. The nurse removes tubes and dressings and inventories valuables. Treating the body with dignity and honoring the family’s cultural or religious practices is part of the task.²

What You Cannot Do

The prohibitions all trace back to one principle: a licensed nurse cannot delegate nursing judgment to an unlicensed person.³ In day-to-day practice, that rules out five categories of work.

Administering medication in any form, oral, injected, or topical. State nurse practice acts uniformly treat medication administration as a nursing function that requires licensed judgment about dosage, timing, interactions, and patient response.
Performing sterile procedures, including inserting urinary catheters, managing IV lines, and changing deep wound dressings.
Conducting patient assessments to determine a diagnosis or clinical status. You gather the data; you do not interpret what the numbers mean clinically.
Creating or modifying a plan of care. The nursing process of assessment, diagnosis, planning, and evaluation is reserved for licensed nurses.
Providing medical advice. Explaining a prognosis, recommending treatments, or interpreting test results to a patient or family crosses into the practice of nursing or medicine.

The line shows up in small moments. If you record a blood pressure of 180/110, you document it and tell the supervising nurse immediately. You do not tell the patient the reading is dangerous or suggest what to do about it. Questions from patients or family about a condition, treatment, or prognosis go to the licensed nursing staff, every time. Federal curriculum standards reinforce this: aides are trained to recognize abnormal changes and report them to a supervisor, not act on them.²

How Delegation and Supervision Work

Nursing assistants do not practice independently. Federal rules require Medicare- and Medicaid-certified facilities to staff each shift with a licensed nurse as charge nurse, and to confirm that aides have demonstrated competency in the skills their assigned patients need.⁴ Every task you perform flows from delegation by a registered nurse or LPN who has assessed the patient and decided the task is appropriate for you.

The standard framework for that decision is the five rights of delegation:

Right task: the activity is within the CNA job description and the facility’s written policies.
Right circumstance: the patient is stable enough that the outcome is predictable.
Right person: this aide has the training and demonstrated competency for the task.
Right direction: the nurse gives clear, specific instructions, including what to watch for and when to report back.
Right supervision: the nurse stays available to intervene and evaluates the outcome.

Accountability splits in a way that catches some CNAs off guard. The delegating nurse keeps overall accountability for the patient’s outcome, but you carry the responsibility for performing the delegated task correctly.³ You cannot change how a task is performed without checking with the nurse first. If the patient’s condition shifts mid-task, stop and notify the nurse. Most scope problems start when an aide senses something is off and tries to handle it instead of escalating.

Blood Glucose and Medication Aide Add-Ons

Some scope items depend entirely on the state. Fingerstick blood glucose testing is one. Where your state’s nurse practice act allows a trained aide to perform it under nurse delegation, CDC infection control standards govern the technique: single-use auto-disabling lancets, meters assigned to individual patients whenever possible, gloves during every test, and hand hygiene right after removing gloves. Meters that must be shared have to be cleaned and disinfected per the manufacturer’s instructions after each use.⁵

Medication administration is the other. Roughly 36 states permit some form of medication aide practice, but the details vary widely. Most require an active CNA certification in good standing, additional training that runs from around 45 to 140 hours of classroom and clinical work, and a separate competency exam. Some states also require prior CNA experience, often six months to two years.

Even with the certificate, the scope stays narrow. Medication aides typically give routine oral medications to stable patients under a licensed nurse’s supervision. Injectables, controlled substances in many jurisdictions, and medications that need clinical judgment about timing or dosage adjustments remain outside the aide’s authority. Read the specific provisions of your state’s nurse practice act before signing up for the training.¹

Emergency Response and Mandatory Reporting

Safety and emergency procedures, including response to airway obstruction, are part of the federal training that must be completed before any direct resident contact.² When a resident is choking, the immediate priorities are calling for help and checking whether the person can cough, breathe, or speak. If you have been trained in abdominal thrusts, you can attempt to clear the airway while licensed staff arrive.

Many employers require you to maintain a current Basic Life Support certification. The AHA’s BLS course covers high-quality CPR for adults, children, and infants, early AED use, effective ventilation, and airway obstruction relief. BLS certification is valid for two years.⁶ Your role in an emergency is to stabilize and bridge until a licensed provider takes over, then report the timeline, interventions, and patient response to the supervising nurse.

Reporting suspected abuse, neglect, exploitation, or misappropriation of resident property is not optional. Under 42 CFR 483.12, anyone who forms a reasonable suspicion that a crime has been committed against a resident must report it to the state survey agency and to law enforcement. The deadline is two hours if the events caused serious bodily injury, and 24 hours otherwise.⁷ You do not have to be certain that abuse occurred; a reasonable suspicion is enough to trigger the duty. Federal law prohibits retaliation against employees who report.

Keeping Your Certification and Registry Status

Certification is not permanent on its own. Federal rules require nurse aides in certified facilities to complete at least 12 hours of in-service training every year, and that annual training must include dementia management and resident abuse prevention.⁸

Every state also maintains a nurse aide registry that lists your name, certification date, and any findings of abuse, neglect, or misappropriation. Only the state survey and certification agency can enter those findings, and once entered they can never be removed.⁹ Employers check the registry before hiring, so a finding effectively closes off nurse aide work nationwide.

There is also a use-it-or-lose-it rule. If you go 24 consecutive months without performing any nursing or nursing-related work, the state must remove your name from the active registry. After that, most states require you to retake the competency evaluation, and some require additional training before you can test again.

Reciprocity is not automatic between states. If you move, the new state’s board or registry evaluates your credentials individually. Expect to show proof of active certification with no negative findings, submit your training documentation, pass a criminal background check, and in some cases retake the competency exam if your original training does not meet the new state’s hour requirements. Contact the receiving state’s registry before you move so you do not lose working time.

Consequences of Crossing the Line

Practicing outside your authorized scope can end your career and expose you to criminal charges. Your state board can revoke your certification and place a permanent finding on your registry record. Penalties for practicing nursing without a license are set by each state’s nurse practice act and vary, but commonly include fines and possible jail time, particularly if a patient is harmed.¹ When a patient is injured, prosecutors may add charges such as battery or reckless endangerment. Even incidents that look minor at the time can leave a registry finding that follows you for the rest of your career.

On the supervisory side, both the aide and the delegating nurse can face discipline when the chain breaks. The nurse can be sanctioned for delegating inappropriately, and you can be sanctioned for performing tasks without proper authorization. The safest habit when a situation drifts toward the edge of your scope is the one federal training teaches: stop, and report to the nurse.
