What should the nurse tell a patient who questions the prescription of timolol for glaucoma, thinking it is only for heart problems?

The best answer provides clarity on the dual uses of timolol and effectively addresses the patient's misunderstanding about its intended purpose. Timolol is indeed primarily recognized as a beta-blocker used in treating heart conditions, but it also has significant applications in ophthalmology, particularly in managing intraocular pressure in glaucoma patients.

The correct perspective informs the patient that the medication can be utilized in various formulations (oral and topical) for different health issues, including its specific role as an eye drop treatment for glaucoma. This helps the patient to understand that timolol's prescription is not limited to cardiovascular conditions but extends to ocular health, thereby reducing any anxiety they might have about its use in their treatment plan.

The other responses do not effectively clarify the medication's role in treating glaucoma or might confuse the patient further. For instance, stating that it acts as a diuretic or suggesting to contact a health care provider lacks reassurance and confidence in the prescribed treatment. The focus should remain on the established functions of the medication to foster understanding and adherence to the treatment.
