In preparation for cataract surgery, the nurse is to administer cyclopentolate (Cyclogyl) eyedrops. The nurse understands that which characterizes the medication action?

a) Hypertension: Pseudoephedrine is a sympathomimetic drug that can cause vasoconstriction, leading to increased blood pressure. Clients with hypertension are at higher risk for complications such as increased blood pressure, stroke, or other cardiovascular events.
b) Overweight: While being overweight may contribute to other health concerns, it does not specifically interact with pseudoephedrine in a way that places the client at risk for harm.
c) Eczema: Eczema, a skin condition, does not directly interact with pseudoephedrine and is not a contraindication for its use.
d) Migraine headaches: Although migraine sufferers may be sensitive to certain medications, pseudoephedrine does not pose a direct risk to clients with migraines. However, caution may be needed for any individual who is sensitive to changes in blood pressure.

a) "I should call the clinic before taking any over-the-counter medications.": Over-the-counter medications, especially decongestants and antihistamines, can increase intraocular pressure and should be used with caution in glaucoma patients.
b) "Every two years I will need to have my vision checked by an eye doctor.": This is incorrect because glaucoma patients need more frequent eye exams, typically every 6 to 12 months.
c) "If I forget to take my eye drops, I should wait until the next time they are due.": The client should take the missed dose as soon as remembered, unless it is close to the next scheduled dose. Waiting could result in elevated intraocular pressure.
d) "When my vision improves, I will be able to stop taking the eye drops.": Vision may not improve with glaucoma treatment, and medications should be taken consistently to manage intraocular pressure, even if symptoms are controlled.
