2.1 The CNA Role, Scope & Delegation
Key Takeaways
- A New Jersey CNA always works under the direction and supervision of a licensed nurse (LPN or RN) and may never assess, diagnose, develop the care plan, or give medications.
- Delegation flows down the chain of command from the physician and RN to the LPN to the CNA; accountability for the delegated task is shared, and the CNA stays personally responsible for performing it correctly.
- If a delegated task is unsafe, outside your training, or not on the care plan, you must decline and notify the nurse rather than perform it — refusing an unsafe assignment is not insubordination.
- Observing and reporting is a core CNA duty: report any change in a resident's condition to the licensed nurse promptly, and document objective facts only (what you saw, measured, or were told).
- Documentation must be timely, accurate, legible, and signed; never chart care before it is given or document for another aide.
Why Scope of Practice Matters
The Role of the Nurse Aide is roughly a quarter of the New Jersey written exam, and scope questions appear in almost every domain. Working within your scope protects residents from harm and protects your place on the New Jersey Nurse Aide Registry. A single task performed outside your role — giving a medication, interpreting a lab value, or changing a care plan — can trigger a substantiated finding and revocation.
CNA Duties vs. Licensed Nurse Scope
A Certified Nursing Assistant (CNA) provides hands-on supportive care under the direction of a Licensed Practical Nurse (LPN) or Registered Nurse (RN). The nurse owns clinical judgment; the CNA carries out delegated, routine tasks and reports what is observed.
| Function | CNA | Licensed Nurse (LPN/RN) |
|---|---|---|
| Bathing, dressing, feeding, toileting | Yes | Delegates and oversees |
| Vital signs, intake and output, weights | Yes | Interprets the values |
| Repositioning, transfers, range of motion | Yes | Plans the activity orders |
| Nursing assessment / diagnosis | No | Yes |
| Care-plan development | No | Yes |
| Medication administration | No | Yes |
| Sterile/invasive procedures | No | Yes (per scope) |
The CNA collects data (a temperature reading); the nurse assesses (decides the temperature means infection). Knowing that line is the most tested concept in this domain.
Chain of Command
New Jersey long-term care facilities use a defined reporting structure. A CNA who is unsure, witnesses a problem, or disagrees with an assignment moves up this chain — never around it.
Delegation and Accountability
Delegation is the transfer of a task from a licensed nurse to a CNA while the nurse keeps responsibility for the outcome. Before accepting a delegated task the CNA should confirm the Five Rights of Delegation: the right task, right circumstance, right person, right direction/communication, and right supervision.
Accountability is shared but not erased. The nurse is accountable for delegating appropriately; the CNA is accountable for performing the task correctly, within training, and for reporting results. If a task is outside your training, unsafe for that resident, or not on the care plan, decline it and tell the nurse. Saying "I have not been trained to do that" is the safe, correct, and registry-protecting answer.
Observing and Reporting
Because the CNA spends the most time at the bedside, the CNA is the facility's early-warning system. Report promptly any change: new confusion, skin breakdown, refusal to eat, a fall, a complaint of pain, or unusual behavior. Subjective complaints ("my chest hurts") and objective findings (BP 90/50, reddened heel) both go to the licensed nurse without delay.
Documentation Basics
Document objective, factual observations using approved facility forms or the electronic record. Chart only after care is given, only what you personally did or witnessed, and never for another aide. Errors are corrected per facility policy (single line, initial, date) — never erased or whited out. If care was not documented, it is treated as not done.
A licensed nurse on a New Jersey skilled nursing unit asks a CNA to push the resident's IV pain medication because the nurse is busy with an admission. What is the CNA's most appropriate response?
While giving morning care, a CNA notices a new quarter-sized reddened area over a resident's tailbone that does not blanch. The next shift's CNA is about to arrive. What should the CNA do?
