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."
- correct answer-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." - correct answer-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. - correct answer-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. - correct answer-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. - correct answer-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 - correct answer-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." - correct answer-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 - correct answer-d. Lower conjunctival sac
