Which task is NOT a duty of a Certified Nursing Assistant (CNA)?

A Certified Nursing Assistant (CNA) plays a critical supportive role in patient care, focusing primarily on assisting patients with activities of daily living. Administering medications, however, is not within the scope of practice for CNAs, as this duty typically requires a higher level of training and certification, usually reserved for licensed practical nurses (LPNs) or registered nurses (RNs).

In contrast, helping residents take baths, keeping a resident's room clean, and applying ice packs are all tasks that fall within the CNA's responsibilities. These duties are essential for maintaining the comfort, hygiene, and overall well-being of the residents under their care. Thus, option B correctly identifies a task that is outside the CNA's scope of practice.
