A 45-year-old male with end-stage renal disease requires hemodialysis to survive. He is fully competent and understands the implications of his decision, but he adamantly refuses dialysis, stating he no longer wishes to prolong his life. His family implores the physician to persuade him or seek a court order to initiate treatment. What is the physician's most appropriate ethical responsibility in this situation?
✓ Correct Answer: Option B
A competent patient has the right to refuse any medical treatment, even if life-sustaining. Respecting patient autonomy is paramount. The physician's ethical duty is to ensure understanding and then uphold the patient's informed decision.
