Correct answer: D — Repeat thyroid function tests after about 6 to 8 weeks

TSH responds gradually to levothyroxine dose changes, so repeat thyroid function testing is delayed for several weeks. This makes repeat thyroid function tests after about 6 to 8 weeks the single best answer in this scenario. The other options would either miss the key safety issue, delay appropriate review, or fail to meet the relevant clinical or professional requirement.
