A nurse in a mental health facility is caring for a client who expresses anxiety about exercising in the outdoor courtyard. The nurse promises to walk with the client in the courtyard each day. Which of the following ethical principles is the nurse demonstrating?

A. "Justice." Justice refers to fairness in the distribution of resources, treatment, and care. It involves ensuring that all clients receive equal and appropriate care based on their needs. While justice is an important ethical principle, it is not directly related to the nurse’s promise to walk with the client. B. "Nonmaleficence." Nonmaleficence is the obligation to do no harm. This principle guides nurses in preventing injury, minimizing risks, and ensuring client safety. While supporting the client can help reduce anxiety, the nurse’s action primarily reflects a different ethical principle. C. "Autonomy." Autonomy refers to respecting a client’s right to make their own decisions regarding their care. The nurse should encourage autonomy by allowing the client to choose whether to walk in the courtyard, but the act of making a promise to accompany them aligns more closely with a different ethical principle. D. "Fidelity." Fidelity involves keeping promises and being truthful in professional relationships. By committing to walk with the client daily and following through on that promise, the nurse is demonstrating fidelity by building trust and maintaining professional integrity.
