MULTIPLE CHOICE

 

1. The nurse is caring for a patient who has increased intraocular pressure. The provider has ordered a cholinergic agonist. The nurse will perform a thorough health history to make sure the patient does not have a history of which condition?

a.	Asthma
b.	Diabetes
c.	Hypertension
d.	Renal disease

2. The nurse is performing a medication history on a patient who has glaucoma. The patient cannot remember the name of the drug prescribed but tells the nurse that the drug causes light sensitivity. The nurse knows that the drug is among which class of medications?

a.	Alpha-adrenergic agonists
b.	Beta-adrenergic blockers
c.	Cholinergic agonists
d.	Cholinesterase inhibitors

 

 

ANS:  A

Alpha-adrenergic agonists cause mydriasis, which increases sensitivity to light. Beta-adrenergic blockers cause miosis, which impairs vision in the dark. Cholinergic agonists and cholinesterase inhibitors may cause myopia and will impair vision in the dark.

3. The nurse administers proparacaine HCl (Ophthaine) drops to a patient prior to an eye examination. What sign will the nurse look for to determine when the examination can begin?

a.	Absence of the blink reflex
b.	Blurred vision
c.	Drying of the corneal epithelium
d.	Photophobia

 

 

ANS:  A

Ophthaine is a topical anesthetic for the eye and causes loss of the blink reflex. Drying of the corneal epithelium is a side effect but occurs later as a result of the loss of the blink reflex. Blurred vision and photophobia result from mydriasis and miosis.

4. The nurse is administering timolol (Timoptic) eye drops to a patient who has glaucoma. To prevent bradycardia, the nurse will perform which action?

a.	Apply pressure to the lacrimal ducts.
b.	Have the patient sit up after instilling the drops.
c.	Prepare to administer an alpha-adrenergic agonist.
d.	Wait 5 minutes between drops.

 

 

ANS:  A

Bradycardia is a systemic side effect of timolol. Applying pressure to the lacrimal ducts prevents the medication from being systemically absorbed and causing systemic side effects such as bradycardia.
