A client with glaucoma is prescribed latanoprost (Xalatan). The nurse instructs the client that this medication, a prostaglandin analog, is used for glaucoma because it:
1. is thought to protect neurons from injury.
2. enhances the outflow of aqueous humor.
3. decreases the production of aqueous humor by the ciliary body.
4. has a relatively short duration of action, and adverse effects can be limited.
Correct Answer: 2
Rationale 1: This medication does not protect neurons from injury.
Rationale 2: Prostaglandin analogs are used to treat open-angle glaucoma because they assist the flow of aqueous humor.
Rationale 3: This medication does not decrease the production of aqueous humor by the ciliary body.
Rationale 4: This medication does not have a short duration of action and limited adverse effects.
Global Rationale: Prostaglandin analogs are used to treat open-angle glaucoma because they assist the flow of aqueous humor.
