Core

A patient has terminal lung cancer with poor prognosis. The physician must decide whether to recommend an experimental chemotherapy that may extend life by a few months but has significant toxic side effects. The physician weighs the potential benefit against the risk of harm. Which ethical principle most directly guides this weighing?

Show answer and explanation

Answer: A. Balance of beneficence and nonmaleficence. Four principles of medical ethics: (1) BENEFICENCE: act for patient benefit; (2) NONMALEFICENCE: avoid harm, 'first do no harm' (primum non nocere); (3) AUTONOMY: respect patient's right to make informed choices; (4) JUSTICE: fair distribution of resources and equal treatment. Risk-benefit analysis weighs beneficence (potential benefit) against nonmaleficence (potential harm). The patient's autonomy then determines the final decision after informed consent.

Why the other choices are tempting

  • B. Autonomy is about respecting patient's informed choice (relevant but not the weighing process).
  • C. Justice is about fair resource allocation.
  • D. Confidentiality protects patient information.
  • E. Veracity is truthfulness.
