In preparation for cataract surgery, the nurse is to administer cyclopentolate (Cyclogyl) eyedrops. The nurse understands that which characterizes the medication action?
Produces miosis of the operative eye
Constricts the pupil of the operative eye
Provides lubrication to the operative eye
Dilates the pupil of the operative eye
The Correct Answer is D
a) Produces miosis of the operative eye: Miosis refers to pupil constriction, and cyclopentolate causes pupil dilation, not constriction.
b) Constricts the pupil of the operative eye: Cyclopentolate causes dilation of the pupil, not constriction.
c) Provides lubrication to the operative eye: Cyclopentolate does not provide lubrication. It is used to dilate the pupil and paralyze accommodation for the surgery.
d) Dilates the pupil of the operative eye: Cyclopentolate works as a mydriatic agent, which dilates the pupil to facilitate the surgery by allowing better visualization of the cataract and the lens.
