Correct answer: E — Lithium level, renal function, thyroid function and calcium

This scenario assesses Lithium routine monitoring in a UK pharmacy practice context. Lithium requires concentration and organ-function monitoring because toxicity is linked to renal function and fluid balance. The best answer is Lithium level, renal function, thyroid function and calcium because it addresses the principal clinical, legal or safety issue before routine supply. The other options are less appropriate because they either miss the key risk, delay necessary review, or would not meet expected BNF, NICE, MEP, MHRA or GPhC practice standards.
