Correct answer: CDo not supply loperamide and advise urgent clinical assessment

Blood, mucus, fever and abdominal pain suggest invasive infection or inflammatory pathology, where antimotility medicines may be inappropriate. The patient needs clinical assessment and hydration advice. Co-codamol may worsen gut motility and mask symptoms. Stopping fluids increases dehydration risk.
