A patient has a solitary thyroid nodule and a normal TSH. Which test comes next?
Answer and explanation
Correct answer: C. Ultrasound followed by fine-needle aspiration cytology

Answer: Ultrasound and fine-needle aspiration. Why not the others: Ablation and surgery without a diagnosis are inappropriate. Only repeating the TSH would miss cancer.
