Safety!
Mental support
Do NOT drive at night time
Eye proctecton is very important!!
SUrgical care
preope
a) No anathtisa so?
b) Eye dorop for?
a) antianxiety medcation before
b) Nonsteroidal anti-inflammatory
Surgical care
Postope
-outpatient
-eye deops for antibotic,steroid
-Eye shield at night
-Hand hygine
-Activity limitations( do not inc pressure in eye)
bending, stooping, lifting, coughin
-Fall preventation
S/S infection
adjusting to reduce visual aculity after surgery
4-6 weeks
What is macular?
Processes what you see directly in front of you (your central vision).
It’s part of your retina and is key to your vision.
Macular degeneration
a) What is it?
a) No cure
Slow progression
ONLY Lose central vision
b) Aging
Family hx
HTN
Smoking
a) Dry?
b) Wet?
a) Most common
Slower onset
Macular get thinner with age, clumps of protein
b) Less common
Faster onset
Abnormal blood vessels grow under the retina
Glaucoma
a) What is it?
b) Risk?
a) Inc IOP and damage to the optic nerve
(optic nerve atrophy)
NOT curable
A leading cause of permanent blindness
b) Age
Black
Infection
DM
HTN
Tumors
-All about pressure/ pressure dec=eye drop
-eye drop is life long
-Not cure, but manage othwerwise lose more vision
-More than one eye drop
Wait 10-15 mins in between
In a pt who has a hemorrhage in the posterior cavity of the eye, the nurse knows that blood is accumulating
a) in the aqueous humor
b) Between the lens and retina
c) between the cornea adn lens
d) in the space between the iris and lens
b
Ask pt using eyedrops to treat their glaucoma about
a) use of corrective lens
b) their usual sleep pattern
c) a history of heart or lung disease
d) sensitivity to opioids or depressants
c
Always assess the pt with an eye problem for
a) visual acuity
b) pupillary reaction
c) intraocular pressure
d) confrontation visual fields
a
視力
Before injecting fluorescein for angiography, it is important for the nurse to SATA
a) obtain an emesis basin
b) ask if the pt is fatigued
c) administer a topical anesthetic
d) inform pt that skin may turn yellow
e) assess for allergies to iodine-based contrast
a,d
What should be included in the discharge teaching for the pt who had cataract surgery? SATA
a) eye discomfort is often relieved with mild analgesics
b) A decline in visual acuity is common for the first week
c) Stay on bed rest and limit activity for the first few days
d) Notify the provider if an increase in redness or drainage occur
e) Following activity restrictions is essential to reduce intraocular pressure
a,d,e
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.
c
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.
Which finding related to primary open-angle glaucoma would the nurse expect to find when reviewing a patient’s history and physical examination report?
a) Absence of pain or pressure
b) Blurred vision in the morning
c) Seeing colored halos around lights
d) Eye pain accompanied with nausea and vomiting
a
painless, gradual
Primary open-angle glaucoma is typically symptom free, which explains why patients can have significant vision loss before a diagnosis is made unless regular eye examinations are being performed. Primary angle-closure glaucoma signs and symptoms include sudden, excruciating pain in or around the eye, seeing colored halos around lights, and nausea and vomiting.
The patient reports a loss of central vision. What test should the nurse teach the patient about to identify changes in macular function?
a) Amsler grid test
b) B-scan ultrasonography
c) Fluorescein angiography
d) Intraocular pressure testing with Tono-Pen
a
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.”
d
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.
A patient with poor visual acuity is diagnosed with age-related macular degeneration (AMD). Which nursing action should be the nurse’s priority?
a) Teach about visual enhancement techniques.
b) Assess coping strategies and support systems.
c) Teach nutritional strategies to improve vision.
d) Assess impact of vision on normal functioning.
d
