Correct answer: A — Check liver function at baseline and follow recommended follow-up intervals

Statins require baseline liver function testing and follow-up according to guidance, commonly around early treatment and subsequent review. Routine creatinine kinase monitoring is not needed in asymptomatic patients, but unexplained muscle pain should prompt assessment. INR and lithium monitoring are unrelated unless the patient takes those medicines. Daily glucose testing solely for statin toxicity is not appropriate.
