Correct answer: C — Lithium level, renal function, thyroid function and calcium according to schedule

Lithium requires regular monitoring because of its narrow therapeutic index and organ toxicity risks. The best answer addresses the key safety, legal or pharmaceutical care issue in the vignette. The other options would either delay appropriate care, create a new risk, or fail to resolve the issue. This is consistent with the cited UK reference for safe pharmacy practice.
