a
a client has been diagnosed with open angle glaucoma during routine eye exam. the client has been prescribed a ftopical b-adrenergic antagonist. client teaching about how this drug works should include which of the following statements? a- lower intraocular pressure by decreasing aqueous humor production b- exert their effects by increasing the effects of ach, thereby increase aqueous outflowthrough contraction of the ciliary muscle and pupillary constriction c- reduce secretion of aqueous humor d- cause an early decrease in production of aqueous humor by constricting the vessels supplying the ciliary body
