مريض بزرق مزمن مفتوح الزاوية ولديه ربو، ووُصف له قطرة تيمولول. ما التصرف الأنسب؟

A client with chronic open-angle glaucoma and asthma is prescribed timolol eye drops. What is most appropriate?

1. Double the drops because asthma is unaffected
2. Clarify the prescription with the doctor because of asthma
3. Give it with the reliever inhaler every single time
4. Give it because none is absorbed into the blood

Answer: B) Clarify the prescription with the doctor because of asthma. Timolol is a non-selective beta-blocker that can be absorbed systemically, causing bronchospasm and bradycardia. The prescription is clarified for an alternative, and punctal occlusion reduces absorption.
