Which medication, if prescribed for the client with glaucoma, should the nurse querry

Choice A rationale Atropine sulfate is a potent anticholinergic and mydriatic agent that causes pupillary dilation and paralysis of the ciliary muscle. In clients with glaucoma, especially narrow-angle glaucoma, dilation of the pupil can block the outflow of aqueous humor through the canal of Schlemm. This blockage causes a rapid and dangerous rise in intraocular pressure, potentially leading to blindness. Nurses must question its use to ensure patient safety and ocular health. Choice B rationale Betaxolol is a cardioselective beta-1 adrenergic antagonist used topically to treat glaucoma. It works by reducing the production of aqueous humor by the ciliary body without significantly affecting the pupil size or visual acuity. Lowering the volume of fluid within the eye helps maintain an intraocular pressure within the safe range of 10 to 21 mmHg. This medication is a standard treatment and would not be questioned by the nurse. Choice C rationale Pilocarpine hydrochloride is a cholinergic agonist or miotic medication. It causes pupillary constriction, which pulls the iris away from the trabecular meshwork. This action improves the drainage of aqueous humor through the natural outflow pathways, thereby reducing intraocular pressure. It is a classic treatment for open-angle glaucoma. Because it actively treats the underlying pathophysiology of high eye pressure, the nurse would recognize it as an appropriate and safe prescription. Choice D rationale The Pilocarpine ocusert is a specialized drug delivery system placed in the conjunctival sac that releases pilocarpine at a controlled rate over one week. Like the liquid form, it promotes miosis and increases aqueous humor outflow to manage intraocular pressure. This system provides more consistent pressure control and improves patient compliance compared to frequent daily drops. It is an appropriate pharmacological intervention for glaucoma management and would not require the nurse to question the order.
