Correct answer: D — Thyroid tests and symptom response take several weeks to stabilise
Levothyroxine has a long biological effect and TSH takes weeks to reflect dose changes. This makes thyroid tests and symptom response take several weeks to stabilise 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.
