Correct answer: A — Seek urgent medical advice because these may indicate bleeding

Black stools and prolonged bleeding can indicate clinically significant anticoagulant-related bleeding. The patient should seek urgent medical advice rather than waiting. Warfarin doses should not be adjusted without professional direction. Consistent diet is more appropriate than permanently avoiding vitamin K-containing foods.
