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.

Explanation
a) 2 weeks: It’s typically too early for fitting a prosthesis after enucleation. Healing time is required before the fitting.
b) 4 weeks: While closer, the patient will likely need a longer healing period before fitting.
c) 8 weeks: Generally, a prosthesis can be fitted around 8 weeks post-enucleation, allowing enough time for the eye socket to heal and settle.
d) 12 weeks: Although healing may take longer, 8 weeks is the most common timeframe for prosthesis fitting.
Correct Answer is A
Explanation
a) Report signs of corneal rejection to the physician: Cloudiness may indicate graft rejection, requiring immediate medical attention.
b) Elevate the patient's head and encourage increased fluid intake: This can help reduce intraocular pressure but does not address corneal rejection.
c) Reassure the patient that cloudiness is normal for several weeks: Persistent cloudiness is not typical and warrants evaluation.
d) Prepare the patient for emergency surgery: Emergency surgery is not the first step unless complications are severe.
