Prioritizing Patient Autonomy in Care Decisions

A nurse is caring for a terminally ill patient who has expressed a desire to refrain from aggressive treatment measures that could prolong their life but also decrease the quality of remaining time. The patient has provided a written document outlining their wishes. The patient's family, however, insists that every possible measure be taken to prolong life. In this situation, the nurse must consider ethical principles when making care decisions.
