A client is receiving latanoprost (Xalatan) for open-angle glaucoma. Which medication information provided by the nurse is incorrect?

Question

1. "The medication will increase the outflow of aqueous humor."
2. "Your eyelashes may grow longer and thicker and could become darker."
3. "Your gray eyes might become more pigmented and turn brown."
4. "You must monitor your blood pressure and pulse prior to administration of this drug."

Answer 1

Correct Answer: 4
Rationale 1: Prostaglandin analogs lower intraocular pressure by increasing the flow of aqueous humor.
Rationale 2: Prostaglandins increase the growth and pigmentation of the eyelashes.
Rationale 3: A harmless brown discoloration can occur with prostaglandin agents used for glaucoma. Stopping the medication will prevent further discoloration, but the existing color changes usually do not regress.
Rationale 4: Prostaglandins have fewer adverse effects than do beta blockers and do not require monitoring of blood pressure or pulse.
