Which of the following is NOT a responsibility of a CNA?

The correct answer is identified as the choice that involves performing complex medical procedures, as this task falls outside the scope of practice for a Certified Nursing Assistant (CNA). CNAs are trained to provide basic care and assist patients with daily living activities, which includes bathing, dressing, and feeding patients. These responsibilities focus on ensuring the comfort and personal hygiene of patients, supporting their overall well-being.

Complex medical procedures, however, require a higher level of training and expertise, typically associated with licensed healthcare professionals such as nurses or doctors. These procedures might involve tasks like administering medications, providing treatment for specific medical conditions, or performing diagnostic tests, which are not within the CNA's training or job description. By recognizing the boundaries of a CNA's role, it becomes clear that duties involving advanced medical procedures are reserved for those with appropriate credentials and training.
