Which is a primary role of a Certified Nursing Assistant related to patient comfort?

The primary role of a Certified Nursing Assistant (CNA) in relation to patient comfort is maintaining a clean and safe environment for patients. This is crucial as it directly impacts the overall well-being of individuals in care. A clean environment helps prevent infections, allows for a more pleasant experience, and promotes safety by reducing hazards, such as slips and falls. By ensuring that patients are in a hygienic and secure setting, CNAs contribute significantly to their comfort and overall health.

Other options, while important in healthcare, do not align with the responsibilities typically assigned to a CNA. Performing complex medical procedures and prescribing medications are duties that require more advanced training and are usually reserved for nurses or physicians. Conducting mental health evaluations also falls outside the CNA's scope of practice, as this requires specialized training in psychological assessment. Therefore, maintaining cleanliness and safety stands out as the most critical role that directly enhances patient comfort, making it the correct choice.
