The preoperative medication sheet identifies that cyclopentolate (Cyclogyl) is prescribed for a client prior to cataract surgery. The nurse understands that the action of the medication is to:
1. Lubricate the affected eye.
2. Dilate the pupil of the affected eye.
3. Promote miosis of the affected eye.
4. Constrict the pupil of the affected eye.
2
Rationale: Cyclopentolate is used for preoperative mydriasis. It is a rapid-acting mydriatic and cycloplegic medication. It becomes effective in 25 to 75 minutes, and the effects last for 6 to 24 hours. "Lubricate the affected eye," "promote miosis of the affected eye," and "constrict the pupil of the affected eye" are not actions of this medication.
