CH. 20 - The nurse is teaching a patient about timolol eyedrops for the treatment of glaucoma. What
statement made by the patient demonstrates that teaching was effective?
a. "I may feel some palpitations after instilling these eyedrops."
b. "I should withhold this medication if my blood pressure becomes elevated."
c. "I should keep my eyes closed for 15 minutes after instilling these eyedrops."
d. "I may have some temporary blurring of vision after instilling these eyedrops." - ANSWERS💫✔️-d. "I
may have some temporary blurring of vision after instilling these eyedrops."
It is common for patients to have a temporary blurring of vision for a few minutes after instilling
eyedrops. This should not cause concern to the patient. Because timolol is a β-blocker, heart rate may
slow, and blood pressure is more likely to decrease if absorbed systemically.
CH. 20 - The nurse is preparing to administer timolol eyedrops for treatment of glaucoma. What
statement made by the patient would cause the nurse to hold the medication and report to the health
care provider?
a. "I have sinusitis."
b. "I have migraine headaches a lot."
c. "I have chronic obstructive pulmonary disease."
d. "I have a history of chronic urinary tract infections." - ANSWERS💫✔️-c. "I have chronic obstructive
pulmonary disease."
Timolol is a nonselective β-adrenergic blocker that could lead to bronchoconstriction and
bronchospasm. For this reason, it should not be used in patients with COPD. Timolol may be used to
treat migraine headaches, and it does not affect sinusitis or chronic urinary tract infections.
CH. 20 - A patient newly diagnosed with glaucoma asks the nurse what has made the pressure in the
eyes so high. Which is the nurse's most accurate response?
,a. Back pressure from cardiac congestion causes corneal edema.
b. Cerebral venous dilation prevents normal interstitial fluid resorption.
c. Increased production of aqueous humor or blocked drainage increases pressure.
d. Congenital anomalies of the lacrimal gland or duct obstruct the passage of tears. - ANSWERS💫✔️-c.
Increased production of aqueous humor or blocked drainage increases pressure.
Intraocular pressure is increased in glaucoma as a result of excess aqueous humor production or
decreased outflow. Cardiac or cerebral circulation changes do not cause glaucoma. Lacrimal anomalies
do not affect aqueous humor production.
CH. 20 - During the course of a health history to assess vision, a patient reports dry eyes. What should
the nurse assess next?
a. Assess for contact lenses.
b. Suggest saline eyedrops.
c. Ask about eyeglass usage.
d. Check the medication list. - ANSWERS💫✔️-d. Check the medication list.
The nurse should evaluate the patient's medication list to identify agents that can contribute to dry eyes
so follow-up nursing care can be planned. Dry eyes aggravate wearing contact lenses, but contact lenses
do not normally cause dry eyes. The nurse should not suggest saline eyedrops until the etiology of the
dry eyes is determined. Eyeglasses do not cause dry eyes.
CH. 20 - When administering eyedrops to a patient with glaucoma, which nursing measure is most
appropriate to minimize systemic effects of the medication?
a. Apply pressure to each eyeball for a few seconds after administration.
b. Have the patient close the eyes and move them back and forth several times.
c. Have the patient put pressure on the inner canthus of the eye after administration.
d. Have the patient try to blink out excess medication immediately after administration. -
ANSWERS💫✔️-c. Have the patient put pressure on the inner canthus of the eye after administration.
Systemic absorption can be minimized by applying pressure to the inner canthus of the eye. The other
options will not minimize systemic effects of the medication.
,CH. 20 - During a health history, a 43-yr-old teacher reports increasing difficulty reading printed
materials for the past year. What change related to aging does the nurse suspect?
a. Myopia
b. Hyperopia
c. Presbyopia
d. Astigmatism - ANSWERS💫✔️-c. Presbyopia
Presbyopia is a loss of accommodation causing an inability to focus on near objects. This occurs as a
normal part of aging process starting around age 40 years. Myopia is nearsightedness (near objects are
clear and far objects are blurred). Astigmatism results in visual distortion related to unevenness in the
cornea. Hyperopia is farsightedness (near objects are blurred and far objects are clearly seen).
CH. 20 - The nurse is providing discharge teaching to a patient with type 2 diabetes after a scleral
buckling procedure. Which statement, if made by the patient, indicates that the discharge teaching is
effective?
a. "I doubt my other eye will ever be affected."
b. "I can expect severe pain after this procedure."
c. "I should avoid lifting heavy objects and straining."
d. "The procedure will correct my vision immediately." - ANSWERS💫✔️-c. "I should avoid lifting heavy
objects and straining."
Patients should avoid heavy lifting (more than 20 lb) and straining. A patient with a detached retina is at
risk for detachment of the other retina. Patients usually have little to no discomfort after scleral
buckling. Severe, persistent pain should be reported immediately to the health care provider. Vision is
restored in about 90% of retinal detachments. Vision will not be restored immediately and takes days to
weeks to improve.
CH. 20 - When administering a scheduled dose of pilocarpine, in which area should the nurse place the
drops?
a. Inner canthus
b. Outer canthus
c. Center of the eyeball
, d. Lower conjunctival sac - ANSWERS💫✔️-d. Lower conjunctival sac
Ocular medications, such as pilocarpine, should be instilled into the lower conjunctival sac. Never apply
eyedrops directly to the cornea. Applying the drops to the inner canthus will cause them to be
distributed systemically.
CH. 20 - The triage nurse at an ambulatory clinic receives a call from a person with possible metal
fragments in both eyes. Which instructions would the nurse provide for emergency care of this potential
eye injury?
a. "Remove any visible metal fragments."
b. "Apply a loose dressing over your eyes."
c. "Rinse your eyes immediately with water."
d. "Keep your eyes open to allow tears to form." - ANSWERS💫✔️-b. "Apply a loose dressing over your
eyes."
An initial intervention for a penetrating eye injury includes covering the eye(s) with a dry, sterile patch
and protective shield. The fragments should not be removed by the person or others. Penetrating eye
injuries should not be irrigated (only irrigate for chemical eye injuries).
CH. 20 - When teaching a patient about the pathophysiology related to open-angle glaucoma, which
statement is most appropriate?
a. "The retinal nerve is damaged by an abnormal increase in the production of aqueous humor."
b. "There is decreased draining of aqueous humor in the eye, causing pressure damage to the optic
nerve."
c. "The lens enlarges with normal aging, pushing the iris forward, which then covers the outflow
channels of the eye."
d. "There is a decreased flow of aqueous humor into the anterior chamber by the lens of the eye
blocking the papillary opening." - ANSWERS💫✔️-b. "There is decreased draining of aqueous humor in
the eye, causing pressure damage to the optic nerve."
With primary open-angle glaucoma, there is increased intraocular pressure because the aqueous humor
cannot drain from the eye. This leads to damage to the optic nerve over time. Primary angle-closure
glaucoma is caused by the lens bulging forward and blocking the flow of aqueous humor into the
anterior chamber.
