Correct answer: C — Thyroid and liver function monitoring, with review for ocular toxicity

Amiodarone is associated with thyroid dysfunction, hepatic toxicity, pulmonary toxicity and ocular adverse effects. Regular thyroid and liver function monitoring is required, and new visual symptoms should be assessed. Weight loss may be a sign of thyrotoxicosis, making the tests particularly relevant.
