Which of the following is NOT a duty of a nursing assistant?

Administering medication is not a duty of a nursing assistant. In a healthcare setting, the role of a nursing assistant typically involves supporting residents with daily living activities, which includes tasks such as feeding residents, assisting with toileting needs, and helping them move safely. These responsibilities focus on providing personal care and ensuring the comfort and safety of residents.

On the other hand, administering medication falls within the scope of practice for licensed nurses and other healthcare professionals who have the required training and certification to manage medication safely and effectively. This duty involves understanding pharmacology, monitoring potential side effects, and ensuring the correct dosages and times for medications, which are responsibilities that nursing assistants are not qualified to perform.
