Which of the following is a duty of a certified nurse assistant?

A certified nurse assistant (CNA) plays a crucial role in the daily care of patients, particularly in assisting them with activities of daily living (ADLs). These activities include essential tasks such as bathing, dressing, grooming, feeding, toileting, and mobility support. By providing assistance with these fundamental aspects of life, a CNA helps ensure that individuals maintain their dignity and quality of life while receiving necessary healthcare.

The other options reflect responsibilities that typically fall outside the scope of a CNA's duties. Developing treatment plans is generally the responsibility of licensed healthcare professionals, such as nurses or doctors, who are trained to assess patient conditions and plan appropriate care. Conducting nutritional assessments is also a specialized task often carried out by registered dietitians or nutritionists, focusing on evaluating a patient's dietary needs based on various factors. Lastly, performing high-level medical procedures is reserved for trained and licensed healthcare providers, such as nurses, physicians, or specialists, who have the qualifications to perform complex medical tasks. Therefore, option B accurately represents the primary responsibilities of a certified nurse assistant within the healthcare team.
