3.1 Scope of Practice, Delegation & the Healthcare Team
Key Takeaways
- A Wisconsin CNA provides nurse-delegated, supervised direct care; the nurse remains accountable for the decision to delegate, and the CNA is responsible for performing accepted tasks correctly and reporting back.
- CNAs assist with ADLs, hygiene, mobility, vital-sign measurement, observation, and factual reporting — they do not assess, diagnose, write orders, give medications, or perform sterile/invasive procedures.
- Accept only tasks within your training, facility policy, and Wisconsin DHS 129 nurse-aide role; when rules conflict, follow the most restrictive limit and ask the nurse.
- Use the chain of command: report changes and concerns to the licensed nurse (RN or LPN), not directly to the physician, family decisions, or social media.
- Role and Responsibility is a Headmaster knowledge domain (about 5 of 75 questions) — many items are pure scope and delegation traps.
Why Scope Matters on the Wisconsin CNA Exam
Role and Responsibility is one of the twelve Headmaster knowledge subject areas on the Wisconsin CNA exam — about 5 of 75 knowledge questions. Many of those items are not clinical puzzles; they ask whether you know your legal and professional limits. Working outside scope can harm a resident, end your job, and put a substantiated finding on the Wisconsin Nurse Aide Registry under Wisconsin’s caregiver rules.
A Wisconsin Certified Nursing Assistant (CNA) — also called a nurse aide — gives hands-on personal care under the supervision of a licensed nurse (RN or LPN). You complete a DHS-approved nurse aide training and competency evaluation program (NATCEP) of at least 75 hours (including at least 16 clinical hours), or another DHS-approved path, then pass the Headmaster knowledge and skills exams. Once listed on the registry, you practice within the nurse-aide role described in Wis. Admin. Code ch. DHS 129 and your employer’s policies — not as an independent practitioner.
Scope of practice is the set of tasks you may perform based on:
- Federal nurse-aide expectations (OBRA) and Wisconsin DHS 129
- Your completed training and competency check-offs
- The licensed nurse’s delegation
- Facility policy (which may restrict tasks further, never expand them illegally)
When those layers conflict, follow the most restrictive rule and ask the nurse. “A coworker does it” or “the family asked me” is never a defense on the exam or on the unit.
What Wisconsin CNAs Do
Think of CNA work as assist, observe, measure, record, and report — not assess, diagnose, prescribe, or treat independently.
| Care area | Typical CNA tasks |
|---|---|
| Activities of daily living (ADLs) | Bathing, dressing, grooming, oral care, toileting, perineal care |
| Hygiene & comfort | Bed baths, linen changes, positioning for comfort, back rubs as allowed |
| Mobility | Transfers, ambulation with gait belt when ordered/trained, passive ROM as assigned |
| Vital observations | Temperature, radial pulse, respirations, blood pressure if trained/facility allows, height/weight, intake & output |
| Nutrition | Meal setup, feeding assistance, recording meal intake and fluids |
| Elimination | Bedpan/urinal, external catheter care, emptying drainage bags and recording output |
| Safety | Call light in reach, fall precautions, clean spills, follow isolation precautions |
| Communication | Factual reporting to the nurse; documenting care given per facility rules |
Observation is always in scope. You are the team member who often spends the most time at the bedside. Noticing new confusion, a reddened heel, poor intake, or shortness of breath — and telling the nurse promptly — is core CNA work. You do not decide what the change means or invent a treatment plan.
Example: Stay in Scope
A resident’s calf is newly warm, red, and swollen. The correct CNA action is keep the resident safe, avoid massage or heat, and report immediately to the nurse. The CNA does not tell the family “it is probably a strain,” does not elevate on independent clinical judgment if that conflicts with orders, and does not wait until end of shift to mention it.
Tasks Outside CNA Scope
Anything that requires a nursing license, sterile invasive technique, or independent clinical judgment is outside CNA scope unless a separate legal pathway (for example, medication-aide credentials in some settings) and facility authorization apply. On the Wisconsin Headmaster exam, treat the following as out of scope for a standard CNA:
| Out-of-scope act | Why |
|---|---|
| Administering medications (oral, topical, injections, eye drops) | Requires licensed nurse (or separate authorized credential) |
| Inserting catheters, IVs, or feeding tubes | Invasive / sterile nursing procedure |
| Sterile dressing changes, suctioning advanced airways | Requires nursing skill and judgment |
| Adjusting oxygen liter flow without nurse direction per policy/order | Order-driven nursing responsibility |
| Assessing, diagnosing, interpreting lab results | Nursing/medical judgment |
| Writing or changing orders or the care plan | Licensed staff only |
| Taking verbal or telephone orders from a physician | Nurse responsibility |
| Giving medical advice or new treatment instructions to residents/families | Licensed staff responsibility |
Key exam trap: A nurse, doctor, or family member cannot make an illegal task legal by simply asking. If the task is outside CNA scope or you are not trained, you must refuse professionally and escalate through the nurse.
Delegation and Accepting Tasks
Delegation is the process by which a licensed nurse assigns a specific task to a CNA while keeping accountability for the nursing judgment and overall plan of care. The CNA who accepts a task is responsible for performing it correctly, asking questions when unclear, and reporting results and changes.
Wisconsin DHS 129 frames nurse aides as personnel who work under nurse supervision after approved training and competency evaluation. In practice, that means:
- The nurse may only delegate tasks appropriate for a nurse aide — not the nursing process steps of comprehensive assessment, nursing diagnosis, care-plan development, or evaluation of outcomes.
- You may accept only tasks you have been trained and facility-checked to perform for that resident in that circumstance.
- If anything is unsafe, unclear, or outside training, stop and clarify before starting.
Five Rights of Delegation (CNA View)
Nurses use the five rights of delegation. As a CNA, use the same checklist before saying yes:
| Right | CNA check |
|---|---|
| Right task | Is this an approved nurse-aide task under DHS 129 / facility policy? |
| Right circumstance | Is the resident stable enough for me to do this now? |
| Right person | Am I trained and competent on this skill/equipment? |
| Right direction | Do I know what to do, what to watch for, and what to report? |
| Right supervision | Is the nurse available for questions and follow-up? |
Professional refusal language: “I have not been checked off on that mechanical lift. Can you assist or train me first?” What you must not do: attempt the task anyway to look cooperative, silently skip it, or hand it off without telling the nurse.
Chain of Command and the Healthcare Team
Wisconsin facilities use a licensed team. Knowing roles helps you report to the right person and stay in scope.
| Team member | Main role | How the CNA interacts |
|---|---|---|
| RN | Assessment, care planning, medications, supervision, evaluation | Receives reports; delegates; remains accountable |
| LPN | Treatments, many medications, direct supervision of aides in many settings | Often your day-to-day supervisor |
| Physician / advanced practice provider | Diagnosis and medical orders | Your observations reach them through the nurse |
| Physical / occupational / speech therapist | Mobility, ADLs, swallowing/diet texture | Follow precautions; reinforce therapy plans |
| Dietitian | Nutrition plans, special diets | Report intake, preferences, swallowing concerns to nurse/dietitian path |
| Social worker | Psychosocial needs, discharge planning, resources | Report mood, isolation, family concerns through proper channels |
| Activities / recreation staff | Engagement and quality of life | Support participation; report refusal or decline |
Chain of command for clinical issues: CNA → licensed nurse (LPN/RN) → nurse supervisor / charge nurse → director of nursing / administration as policy directs. For non-urgent workplace issues (scheduling, interpersonal conflict), use the facility’s stated leadership path. For abuse or neglect, report immediately through the employer’s required chain (covered in section 3.3) — never “wait and see.”
Wisconsin Framing Tips for Headmaster
- Knowledge exam: 75 questions, 60 minutes, pass ≥ 71%; Role and Responsibility is a small but high-stakes slice.
- Skills exam still reflects scope: you perform aide skills (gait belt ambulation, peri care, vitals) — not medication administration or sterile procedures.
- Registry listing means the public and employers can verify you; substantiated misconduct can bar employment in regulated caregiver settings.
Putting It Together on Test Day
When a question describes a request — give a pill, change a sterile dressing, call the doctor yourself, diagnose chest pain, or wait until tomorrow to report a fall — choose the option that:
- Keeps the resident safe now
- Stays inside CNA scope
- Uses the nurse and chain of command
- Reports facts promptly without inventing a diagnosis
That pattern scores points on Wisconsin Headmaster Role and Responsibility items and builds safe habits for clinical work.
