Correct answer: E — Seek urgent advice for black stools, blood in urine, severe bruising or prolonged bleeding

Warfarin counselling should include bleeding red flags and INR adherence. In this vignette, "Seek urgent advice for black stools, blood in urine, severe bruising or prolonged bleeding" is the safest single best answer. The other options are less appropriate because they miss the key clinical risk, conflict with UK medicines guidance, or delay needed review.
