Correct Answer is A
Explanation
A. Miotic medications work by constricting the pupil, which opens the trabecular meshwork and facilitates the drainage of aqueous humor, thus lowering intraocular pressure in clients with glaucoma.
B. Miotics do not dilate the pupil; they constrict it. Dilation would actually increase intraocular pressure, which is not therapeutic in glaucoma.
C. While these medications do affect eye muscles, they do not specifically prevent blurred vision; their primary effect is on eye pressure.
D. Miotics do not block nerve responses; they work by direct action on the eye muscles to promote fluid drainage and reduce pressure.
