Chapter 42: Drugs Used to Treat Glaucoma and Other Eye Disorders
Test Bank
MULTIPLE CHOICE
1. The nurse is preparing a patient for an ophthalmic examination. Which action occurs when the
nurse instills eye drops to produce mydriasis?
a. Drying of tears in the eyes
b. Extreme dilation of the pupil
c. Opening of the canal of Schlemm
d. Paralysis of the ciliary muscle
ANS: B
Dilating the eye before eye examinations allows for better visualization of the interior of the
globe. Anticholinergic drugs may produce drying of tears in the eye as an adverse effect of
use. Obstruction of the canal of Schlemm results in glaucoma. Paralysis of the ciliary muscle
is cycloplegia.

2. Which type of medication would be used to dilate the pupils before an eye examination?
a. Osmotics
b. Adrenergic agent
c. Beta adrenergic agent
d. Corticosteroid
ANS: B
Adrenergic agents are sympathomimetic. They cause pupil dilation, increased outflow of
aqueous humor, vasoconstriction, relaxation of ciliary muscle, and a decrease in the formation
of aqueous humor. Adrenergic agents are used to lower intraocular pressure (IOP) in open
angle glaucoma, relieve congestion and hyperemia, and produce mydriasis for ocular
examinations. Osmotics are given to reduce IOP. Beta adrenergics are given for the treatment
of asthma. Corticosteroids are given for acute allergic reactions in the eye.

3. Which medication is used to produce miosis following a diagnostic procedure?
a. Pilocarpine (Pilocar)
b. Mannitol (Osmitrol)
c. Atropine (Isopto Atropine)
d. Epinephrine (EpiPen)
ANS: A
Pilocarpine is a direct acting cholinergic agent that is used to counter the effects of mydriatic
and cycloplegic agents after surgery or eye ophthalmoscopic examinations. Cholinergic

agents also reduce IOP in glaucoma patients by widening the filtration angle that permits
outflow of aqueous humor. Mannitol is an osmotic diuretic given to decrease ocular pressure
by drawing aqueous humor from the eye. Atropine is a mydriatic agent given to dilate the
pupil. Epinephrine may be used to treat certain types of glaucoma.

4. Which discharge instruction will the nurse include for a patient sent home from the clinic
who is taking an adrenergic ophthalmic solution for an acute inflammation?
a. Headaches and eye pain are adverse effects to be reported to the health care provider
immediately.
b. Mouth dryness should be reported immediately.
c. Avoid driving or operating machinery until blurring subsides.
d. “Halos” or yellow rings around objects will be seen while taking this medication.
ANS: C
Adrenergic agents cause the smooth muscle of the ciliary body and iris to relax, producing
mydriasis. Blurred vision will temporarily occur until the patient can adjust to the increased
light coming into the eyes. Activities such as driving or operating machinery should be
avoided until vision stabilizes. Sunglasses help reduce the brightness. These are common,
mild adverse effects and usually resolve with continued therapy. Mouth dryness is a common
adverse effect. Halos are a sign of acute closed angle glaucoma.

5. What is the action of timolol maleate (Timoptic), a beta adrenergic blocking agent?
a.Draws aqueous humor from the eye into the circulatory network
b.Increases the production of aqueous humor
c.Increases the outflow of aqueous humor
d.Decreases the production of aqueous humor
ANS: D
Timolol maleate is a beta adrenergic blocking agent used to reduce increased intraocular
pressure. The exact mechanism of action of these medications is unknown, but they are
believed to reduce the production of aqueous humor. Timolol is believed to decrease
production of aqueous humor.

6. What is the mechanism of action of osmotic agents when used to decrease IOP?
a. Promoting outflow of the aqueous humor into the tear ducts
b. Increasing plasma osmolarity and drawing extracellular fluid into the blood
c. Blocking production of aqueous humor
