What term describes the obligation to act according to ethical principles?

The correct choice is the term that best encapsulates the obligation to act in accordance with ethical principles. This concept emphasizes the duties and accountability individuals have, particularly in contexts such as healthcare, where caregivers must adhere to standards that promote well-being and trust. Responsibility involves recognizing the moral or ethical implications of one's actions and ensuring that they align with established values and principles.

Integrity, while related, focuses more on the commitment to honesty and maintaining moral values, rather than the broader obligation of ethical action. Ethics itself refers to the study or system of moral principles but does not specifically denote the action. Justice, on the other hand, pertains to fairness and the equitable treatment of individuals, which, while important, is a specific aspect of ethical considerations rather than the general obligation to act ethically.
