Which tasks are nursing assistants not allowed to perform?

• A. Insert or remove tubes
• B. Take vital signs
• C. Provide assistance with daily living activities
• D. Assist with routine hygiene

Answer: (A)

The key idea is understanding what a CNA is legally allowed to do within their role. CNAs provide basic comfort and daily care under supervision and can take vital signs, help with activities of daily living, and assist with routine hygiene. Inserting or removing tubes is an invasive procedure that requires medical judgment, sterile technique, and authorization by a licensed nurse or physician. Because this goes beyond the CNA scope, it’s not within what a CNA may perform. If a tube needs attention, the CNA should report to the nurse so the appropriate licensed provider can handle it.
