A psychiatric nurse best implements the ethical principle of autonomy when he or she:

A) intervenes when a self-mutilating patient attempts to harm self.
B) stays with a patient who is demonstrating a high level of anxiety.
C) suggests that two patients who are fighting be restricted to the unit.
D) explores alternative solutions with a patient, who then makes a choice.

Autonomy is the right to self-determination, that is, to make one's own decisions. When the nurse explores alternatives with the patient, the patient is better equipped to make an informed, autonomous decision. Staying with a highly anxious patient or intervening with a self-mutilating patient demonstrates beneficence and fidelity. Suggesting that two fighting patients be restricted to the unit demonstrates the principles of fidelity and justice.
