This document discusses two theories of ethics - utilitarian ethics and principle-based ethics - and how they would apply to a scenario where a doctor must decide whether to override a patient's do-not-resuscitate (DNR) order to fulfill the wishes of the patient's family members. Under utilitarian ethics, which aims to benefit the majority, the doctor would override the DNR; but under principle-based ethics, which focuses on individual rights, the doctor would honor the patient's signed DNR as their right and wish. The document analyzes the strengths and weaknesses of each approach.
