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

Assisting patients with bathing and grooming is indeed a common task performed by Certified Nursing Assistants (CNAs). This role is essential in providing basic personal care and promoting the hygiene and comfort of patients. CNAs often help individuals who may have difficulty performing these activities independently due to age, illness, or disability. Bathing and grooming not only play a crucial part in maintaining physical health, but they also boost patients' morale and sense of dignity.

In contrast, conducting physical examinations, prescribing medications, and administering intravenous therapy are responsibilities that require a higher level of medical training and certification. These tasks are typically performed by nurses or physicians, who have the necessary education and licensure to carry out such complex and critical functions. Thus, the assistance with bathing and grooming stands out as a fundamental duty that aligns with the scope of practice for CNAs.
