CNA Scope of Practice

The scope of practice defines what a Certified Nursing Assistant is legally permitted to do. Understanding your scope of practice is essential for providing safe patient care and protecting your certification.

What is Scope of Practice?

Scope of practice refers to the range of responsibilities and activities that a healthcare professional is legally authorized to perform based on their education, training, and certification. For CNAs, this scope is defined by:

  • State nurse practice acts - Laws that define nursing roles
  • State nursing board regulations - Specific rules for CNAs
  • Facility policies - Additional restrictions at your workplace
  • Federal regulations - OBRA requirements for nursing facilities

Always check your state's specific regulations and facility policies.

The Importance of Staying Within Scope

Performing tasks outside your scope of practice can result in:

  1. Harm to the patient - Lack of training can cause injury
  2. Loss of certification - State board can revoke your CNA
  3. Legal liability - You can be sued for negligence
  4. Criminal charges - Serious violations may be prosecuted
  5. Termination - Employers must take action

What to Do if Asked to Perform an Unauthorized Task

If anyone asks you to perform a task outside your scope:

  1. Politely decline - "I'm not trained/authorized to do that"
  2. Explain your scope - "That requires a licensed nurse"
  3. Offer alternatives - "I can help you find the nurse"
  4. Document if needed - Record inappropriate requests
  5. Report concerns - Notify your supervisor
