Final answer:
Administering pain medication as prescribed is an action that shows a nurse is practicing ethically by prioritizing patient comfort and adhering to medical ethics. Ethical care involves palliative measures and respect for patient autonomy and informed consent.
Step-by-step explanation:
A nurse who is caring for a terminally ill client demonstrates ethical practice by administering pain medication as prescribed. This action aligns with the principles of medical ethics which emphasize patient autonomy, alleviating suffering, and providing compassionate care. Withholding information, encouraging refusal of treatment, and restricting family visits do not foster an ethical approach to end-of-life care. Hospice care, for instance, focuses on comfort and supports the right of patients to be informed and participate in their care decisions. Ethical practice involves transparency, respect for the patient's wishes, and a commitment to providing palliative care aimed at relieving pain and other distressing symptoms.
