Correct answer: ADecline loperamide and arrange urgent assessment of febrile bloody diarrhoea

Decline loperamide and arrange urgent assessment of febrile bloody diarrhoea: Dysentery features suggest invasive infection; slowing intestinal transit may worsen illness or obscure severity and antimicrobial assessment may be needed. Supply maximum-dose loperamide and review symptoms after 48 hours: Bloody febrile diarrhoea is a contraindication to unsupervised antimotility treatment. Combine loperamide with a previously prescribed travel antibiotic course: Leftover antimicrobials may be ineffective or harmful and do not replace assessment. Withhold fluids until visible blood has cleared from the stool: Fluid replacement is important and fasting does not treat invasive infection. Offer oral rehydration alone and review if fever persists for seven days: Fever and blood increase concern for invasive bacterial disease and warrant prompt assessment.
