What are CNA's not authorized to do in relation to oxygen administration?

Certified Nursing Assistants (CNAs) are trained to provide support in a variety of patient care tasks but have specific limitations regarding certain medical procedures. In the context of oxygen administration, CNAs are not authorized to change the flow rate or administer oxygen themselves.

The rationale behind this restriction lies in the fact that oxygen administration can be a critical intervention that requires knowledge of the patient's condition, specific medical orders, and the ability to recognize any adverse effects. The adjustment of flow rates and administration of oxygen are typically reserved for licensed nursing personnel, such as registered nurses or licensed practical nurses, who are equipped to assess the patient's needs and respond appropriately.

While monitoring oxygen saturation is within the scope of practice for CNAs – as they can perform basic vital sign checks and report findings to the nursing staff – they must not take actions that require clinical judgment or the implementation of medical treatments. Therefore, the correct answer indicates that changing the flow rate and administering oxygen fall outside the authorized duties of a CNA.
