Correct answer: A — Assess thyroid, liver and pulmonary toxicity urgently

Amiodarone can cause thyroid, hepatic and pulmonary toxicity, and new breathlessness requires urgent assessment for lung toxicity. Monitoring commonly includes thyroid and liver function, with assessment for respiratory symptoms and imaging if indicated. INR monitoring is relevant if combined with warfarin, but it is not sufficient for amiodarone safety. Ignoring symptoms could delay recognition of serious harm.
