Correct answer: A — Contact the prescriber to review antimuscarinic suitability

Tiotropium is an inhaled antimuscarinic and can worsen urinary retention or precipitate glaucoma symptoms in susceptible patients. The temporal relationship and comorbidities make this clinically relevant. The pharmacist should arrange prescriber review and advise urgent care if acute eye pain or urinary retention develops.
