Which of the following is a domain of the AANA code of ethics?

• A. Responsibility to patient
• B. Responsibility to education
• C. Responsibility to the environment
• D. Responsibility to families

Answer: (A)

The main idea here is that patient welfare is a formal domain in the AANA Code of Ethics. This code centers on obligations that protect and prioritize the patient: ensuring safety, obtaining informed consent, maintaining confidentiality, respecting patient autonomy, and upholding trust in the patient–provider relationship. Because of that central focus, responsibility to the patient stands out as a recognized domain of ethical practice for nurse anesthesia.

The other topics—environment, families, and education—aren't defined as formal domains within the AANA Code of Ethics. They may be relevant to competent practice and holistic care, but they don’t constitute the official ethical domains described by the code.
