Question

In preparation for cataract surgery, the nurse is to administer cyclopentolate (Cyclogyl) eyedrops. The nurse administers the eyedrops, knowing that the purpose of this medication is to:

Option 1: Dilate the pupil.
Option 2: Constrict the pupil.
Option 3: Reduce intraocular pressure.
Option 4: Prevent infection.

Answer 1

Cyclopentolate (Cyclogyl) is used to dilate the pupil to facilitate cataract surgery, offering better visibility for the surgeon, in contrast with pilocarpine which constricts the pupil.

Step-by-step explanation:

The purpose of administering cyclopentolate (Cyclogyl) eyedrops to a patient in preparation for cataract surgery is to dilate the pupil. Cyclopentolate is a mydriatic agent, which means it causes the pupils to enlarge. This is essential during cataract surgery as it provides the surgeon with better visibility of the lens and the structures within the eye. In contrast to pilocarpine, which is a muscarinic agonist that constricts the pupil and reduces intraocular pressure, cyclopentolate ensures that the pupil is wide enough to facilitate the removal of the cataract-clouded lens.
