Correct answer: B — Withhold aclidinium and arrange urgent assessment for urinary retention and angle-closure glaucoma
Aclidinium has antimuscarinic effects and requires caution in symptomatic prostatic hyperplasia, bladder-neck obstruction and narrow-angle glaucoma. Acute urinary retention and a painful red eye with visual haloes need urgent assessment; further doses should be withheld pending clinical review. Adding another antimuscarinic medicine could worsen both problems, and routine follow-up would be an unsafe delay.
