A nursing assistant is responsible for?

The reason keeping a patient's personal information confidential is the correct answer lies in the fundamental principles of patient privacy and confidentiality in healthcare. Nursing assistants are trained to follow guidelines that ensure patient information is protected in accordance with laws such as the Health Insurance Portability and Accountability Act (HIPAA). Maintaining confidentiality fosters trust between patients and healthcare providers, allowing patients to feel safe to share sensitive information necessary for their care.

In contrast, the other options involve responsibilities that typically fall outside the scope of practice for nursing assistants. For example, answering a patient's letters and phone calls is often administrative work that doesn't align with the core duties of a CNA. Additionally, filing patient complaints with hospital administration is a task more suited for supervisory or administrative staff. Finally, recommending medication and treatments is the responsibility of licensed healthcare professionals, such as doctors or nurses, who have the training and authority to make such decisions. Nursing assistants are critical members of the healthcare team but must operate within their defined roles.
