A nurse is caring for a client with glaucoma who is prescribed a topical beta-adrenergic blocking agent. When teaching this client about the medication, which will the nurse include?
A) Relaxes the ciliary muscle, improving the outflow of aqueous humor and reducing intraocular pressure.
B) May cause blurred vision and stinging.
C) When used long term, causes permanent darkening of the iris of the eye and eyebrows.
D) Reduces intraocular pressure by decreasing the production of aqueous humor in the ciliary body.
Answer: D
Topical beta-adrenergic blocking agents are one type of pharmacological therapy used in the treatment of glaucoma. This class of medication works to reduce intraocular pressure by decreasing the production of aqueous humor in the ciliary body. All other choices are true for prostaglandin analog drugs, another class of medications used in the treatment of glaucoma.
