A 35-year-old Jehovah's Witness with severe gastrointestinal bleeding is alert, oriented, and firmly refuses a blood transfusion, citing religious beliefs, despite understanding the life-threatening risks. What is the most ethically appropriate action for the physician?

✓ Correct Answer: Option B

Competent adult patients have the right to autonomy, including the right to refuse medical treatment, even if life-saving. The physician's ethical duty is to respect this decision, ensure informed refusal, and provide alternative supportive care.
