Which of the following is a common task performed by CNAs?

The common task performed by CNAs is assisting patients with bathing and grooming. This role is essential in providing personal care and support to patients who may have difficulties with these activities due to age, illness, or disability. CNAs are trained to help individuals maintain their hygiene and appearance, which not only promotes physical health but also contributes to the patient’s emotional well-being and dignity.

Bathing and grooming are daily activities crucial for comfort and self-esteem. CNAs typically assist by ensuring that patients are clean and well-groomed, which can include helping with showering, washing hair, and providing oral hygiene. This type of personal care is foundational to the CNA's role and is a significant part of their responsibilities in various healthcare settings.

The other tasks listed are not typically within the scope of a CNA's duties. Conducting patient evaluations is usually performed by licensed nurses or medical professionals who have the required training and expertise to assess a patient's condition comprehensively. Prescribing medication is strictly a function of licensed medical practitioners, such as doctors or nurse practitioners, and performing surgical procedures requires extensive medical training and qualifications that CNAs do not possess.
