Correct answer: A — Stop carbimazole and arrange urgent liver assessment
The best answer is “Stop carbimazole and arrange urgent liver assessment”. Carbimazole can cause serious hepatic injury. Jaundice, dark urine or pale stools require immediate withdrawal and urgent liver assessment; switching to another thionamide before defining the reaction may expose the patient to further harm.
