1.3 CNA Scope of Practice, Delegation & Professional Ethics

1.3 CNA Scope of Practice, Delegation & Professional Ethics

Certified Nursing Assistants (CNAs) serve as essential members of the interprofessional healthcare team, delivering direct, hands-on care to residents in long-term care facilities, hospitals, and community settings. To practice safely and ethically, CNAs must maintain a clear understanding of their legal scope of practice, the principles of nursing delegation, their role within the nursing process, and the ethical standards governing professional caregiving boundaries.

CNA Scope of Practice vs. Licensed Nurse Scope

A healthcare provider's scope of practice defines the procedures, actions, and processes that they are legally permitted to perform based on their education, certification, and state regulatory standards.

In Arkansas, CNAs function under the direct supervision of a licensed nurse—either a Registered Nurse (RN) or a Licensed Practical Nurse (LPN).

Absolute Boundaries of CNA Practice

CNAs must never perform tasks that require independent clinical judgment or specialized licensed nursing skills. Prohibited tasks include:

• Medication Administration: Giving oral, topical, or injectable medications (unless holding a separate Medication Assistant-Certified [MA-C] credential in an authorized facility).
• Sterile Procedures: Performing sterile dressing changes, tracheostomy care, or sterile catheter insertion.
• Invasive Line Management: Inserting, removing, or adjusting IV lines, nasogastric (NG) tubes, or feeding tubes.
• Assessment and Care Planning: Performing initial physical assessments or formulating the resident's plan of care.

The Nursing Process and the CNA's Role

The nursing process is a systematic, clinical decision-making framework utilized by nurses to deliver individualized patient care. It consists of five sequential steps: Assessment, Diagnosis, Planning, Implementation, and Evaluation (often abbreviated as ADPIE).

[Assessment] -> [Diagnosis] -> [Planning] -> [Implementation] -> [Evaluation]

Where the CNA Fits in ADPIE

While the licensed nurse is legally responsible for the overall nursing process, the CNA plays a critical supporting role in two specific phases:

1. Implementation: The CNA executes assigned basic nursing care interventions outlined in the resident's individualized care plan (e.g., repositioning a resident every 2 hours, assisting with meal intake).
2. Observation (Data Collection): During care delivery, the CNA gathers objective data (measurable facts like vital signs, skin redness, or weight) and subjective data (statements made by the resident, such as reporting pain or nausea) and reports them promptly to the charge nurse. The CNA does not perform clinical assessment; rather, they collect and report observational data that feeds into the nurse's ongoing assessment.

Principles of Nursing Delegation

Delegation is the process by which a licensed nurse authorizes a CNA to perform a specific nursing task that is within the CNA's legal scope and competency, while the licensed nurse retains ultimate accountability for the outcome.

The Five Rights of Delegation

To ensure resident safety, all delegation must satisfy the Five Rights of Delegation established by the National Council of State Boards of Nursing (NCSBN):

1. Right Task: The task is within the CNA scope of practice and does not require nursing judgment (e.g., assisting with a bed bath is a right task; evaluating wound healing is not).
2. Right Circumstance: The resident is clinically stable, and the care setting allows safe delegation (e.g., taking routine vitals on a stable resident vs. an unstable resident in acute distress).
3. Right Person: The nurse delegates to a competent CNA who has received verified training, and the task matches the resident's specific needs.
4. Right Direction and Communication: The nurse provides clear, concise instructions detailing specific parameters, limitations, and reporting expectations (e.g., "Obtain Mr. Smith's blood pressure now and report immediately if the systolic exceeds 140").
5. Right Supervision and Evaluation: The nurse provides appropriate monitoring, guidance, and evaluation of the resident's response to the delegated care.

Declining an Assignment Safely

A CNA has the legal and ethical obligation to refuse a delegated task under specific, safety-critical circumstances:

• The task is outside the legal CNA scope of practice in Arkansas.
• The CNA has not been trained or instructed on how to perform the procedure.
• The task requires equipment that is broken, missing, or unsafe.
• The nurse's directions are unclear, contradictory, or unsafe.

When refusing an assignment, the CNA must communicate politely, explain the specific reason for refusal (e.g., "I have not been trained on operating this mechanical lift model"), and immediately request proper instruction or reassignment from the charge nurse to prevent resident abandonment.

Professional Boundaries and Workplace Ethics

Maintaining professional boundaries ensures a therapeutic, safe relationship between the CNA and the resident. Professional boundary violations occur when a caregiver's engagement exceeds therapeutic limits.

Boundaries, Gifts, and Social Media

• Gift Policies: CNAs must strictly adhere to facility policies regarding gifts. Accepting cash, tips, loans, or personal gifts from residents or family members is considered financial exploitation and a boundary violation. Polite refusal is required (e.g., "Thank you so much, but facility rules prevent me from accepting personal gifts").
• Financial Transactions: CNAs must never manage a resident's personal finances, borrow money, or purchase items using a resident's personal credit card or cash.
• Social Media & Confidentiality: Posting photos, videos, or descriptions of residents on social media—even without names—is a severe HIPAA violation and grounds for immediate termination, registry reporting, and potential criminal prosecution.

Work Ethics and Professional Conduct

Professionalism extends to daily work habits and personal accountability:

• Punctuality & Reliability: Arriving on time for assigned shifts prevents understaffing and ensures continuity of care.
• Dependability: Completing assigned duties thoroughly according to the resident's care plan without cutting corners.
• Honesty & Integrity: Immediately reporting mistakes, care errors, or resident incidents to the charge nurse.
