Which of the following scenarios reflects duty-based ethics?

The scenario that reflects duty-based ethics is when a nurse acts according to hospital policies. Duty-based ethics, also known as deontological ethics, emphasizes following rules, principles, and obligations. In this case, the nurse adheres to established hospital policies, which are designed to ensure that medical care is provided consistently and ethically. By following these policies, the nurse fulfills their professional duties and responsibilities, which is at the core of duty-based ethics.

In contrast, the other scenarios do not align with the principles of duty-based ethics. Making treatment decisions based on personal beliefs introduces subjective judgment rather than adherence to duty. Providing care based on patient needs may involve ethical considerations but is more aligned with a consequentialist approach that focuses on outcomes rather than duties. Finally, decisions driven by profit lack the ethical obligation to prioritize patient care and well-being, which is essential in a duty-based ethical framework.
