Ignatavicius Ch 47: Care of Patients with Eye and Vision Problems Flashcards
A client has a corneal ulcer. What information provided by the client most indicates a potential barrier to home care?
a. Chronic use of sleeping pills
b. Impaired near vision
c. Slightly shaking hands
d. Use of contact lenses
a. Chronic use of sleeping pills
Antibiotic eyedrops are often needed every hour for the first 24 hours for corneal ulceration. The client who uses sleeping pills may not wake up each hour or may awaken unable to perform this task. This client might need someone else to instill the eyedrops hourly. Impaired near vision and shaking hands can both make administration of eyedrops more difficult but are not the most likely barriers. Contact lenses should be discarded.
An older client has decided to give up driving due to cataracts. What assessment information is most important to collect?
a. Family history of visual problems
b. Feelings related to loss of driving
c. Knowledge about surgical options
d. Presence of family support
b. Feelings related to loss of driving
Loss of driving is often associated with loss of independence, as is decreasing vision. The nurse should assess how the client feels about this decision and what its impact will be. Family history and knowledge about surgical options are not related as the client has made a decision to decline surgery. Family support is also useful information, but it is most important to get the clients perspective on this change.
A client is in the preoperative holding area waiting for cataract surgery. The client says Oh, yeah, I forgot to tell you that I take clopidogrel, or Plavix. What action by the nurse is most important?
a. Ask the client when the last dose was.
b. Check results of the prothrombin time (PT) and international normalized ratio (INR).
c. Document the information in the chart.
d. Notify the surgeon immediately.
d. Notify the surgeon immediately.
Clopidogrel is an antiplatelet aggregate and could increase bleeding. The surgeon should be notified immediately. The nurse should find out when the last dose of the drug was, but the priority is to notify the provider. This drug is not monitored with PT and INR. Documentation should occur but is not the priority.
A client does not understand why vision loss due to glaucoma is irreversible. What explanation by the nurse is best?
a. Because eye pressure was too high, the tissue died.
b. Glaucoma always leads to permanent blindness.
c. The traumatic damage to your eye was too great.
d. The infection occurs so quickly it cant be treated.
a. Because eye pressure was too high, the tissue died.
Glaucoma is caused when the intraocular pressure becomes too high and stays high long enough to cause tissue ischemia and death. At that point, vision loss is permanent. Glaucoma does not have to cause blindness. Trauma can cause glaucoma but is not the most common cause. Glaucoma is not an infection.
A clients intraocular pressure (IOP) is 28 mm Hg. What action by the nurse is best?
a. Educate the client on corneal transplantation.
b. Facilitate scheduling the eye surgery.
c. Plan to teach about drugs for glaucoma.
d. Refer the client to local Braille classes.
c. Plan to teach about drugs for glaucoma.
This increased IOP indicates glaucoma. The nurses main responsibility is teaching the client about drug therapy. Corneal transplantation is not used in glaucoma. Eye surgery is not indicated at this time. Braille classes are also not indicated at this time.
A client had a retinal detachment and has undergone surgical correction. What discharge instruction is most important?
a. Avoid reading, writing, or close work such as sewing.
b. Dim the lights in your house for at least a week.
c. Keep the follow-up appointment with the ophthalmologist.
d. Remove your eye patch every hour for eyedrops.
a. Avoid reading, writing, or close work such as sewing.
After surgery for retinal detachment, the client is advised to avoid reading, writing, and close work because they cause rapid eye movements. Dim lights are not indicated. Keeping a postoperative appointment is important for any surgical client. The eye patch is not removed for eyedrops.
A client has been taught about retinitis pigmentosa (RP). What statement by the client indicates a need for further teaching?
a. Beta carotene, lutein, and zeaxanthin are good supplements.
b. I might qualify for a retinal transplant one day soon.
c. Since Im going blind, sunglasses are not needed anymore.
d. Vitamin A has been shown to slow progression of RP.
c. Since Im going blind, sunglasses are not needed anymore.
Sunglasses are needed to prevent the development of cataracts in addition to the RP. The other statements are accurate.
A client has a foreign body in the eye. What action by the nurse takes priority?
a. Administering ordered antibiotics
b. Assessing the clients visual acuity
c. Obtaining consent for enucleation
d. Removing the object immediately
a. Administering ordered antibiotics
To prevent infection, antibiotics are provided. Visual acuity in the affected eye cannot be assessed. The client may or may not need enucleation. The object is only removed by the ophthalmologist.
A client who is near blind is admitted to the hospital. What action by the nurse is most important?
a. Allow the client to feel his or her way around.
b. Let the client arrange objects on the bedside table.
c. Orient the client to the room using a focal point.
d. Speak loudly and slowing when talking to the client.
c. Orient the client to the room using a focal point.
Using a focal point, orient the client to the room by giving descriptions of items as they relate to the focal point. Letting the client arrange the bedside table is a good idea, but not as important as orienting the client to the room for safety. Allowing the client to just feel around may cause injury. Unless the client is also hearing impaired, use a normal tone of voice.
A client had proxymetacaine (Ocu-Caine) instilled in one eye in the emergency department. What discharge instruction is most important?
a. Do not touch or rub the eye until it is no longer numb.
b. Monitor the eye for any bleeding for the next day.
c. Rinse the eye with warm saline solution at home.
d. Use all the eyedrops as prescribed until they are gone.
a. Do not touch or rub the eye until it is no longer numb.
This drug is an ophthalmic anesthetic. The client can injure the numb eye by touching or rubbing it. Bleeding is not associated with this drug. The client should not be told to rinse the eye. This medication was given in the emergency department and is not prescribed for home use.
A client is taking timolol (Timoptic) eyedrops. The nurse assesses the clients pulse at 48 beats/min. What action by the nurse is the priority?
a. Ask the client about excessive salivation.
b. Assess the client for shortness of breath.
c. Give the drops using punctal occlusion.
d. Hold the eyedrops and notify the provider.
d. Hold the eyedrops and notify the provider.
The nurse should hold the eyedrops and notify the provider because beta blockers can slow the heart rate. Excessive salivation can occur with cholinergic agonists. Shortness of breath is not related. If the drops are given, the nurse uses punctal occlusion to avoid systemic absorption.
A client has been prescribed brinzolamide (Azopt). What assessment by the nurse requires consultation with the provider?
a. Allergy to eggs
b. Allergy to sulfonamides
c. Use of contact lenses
d. Use of beta blockers
b. Allergy to sulfonamides
Brinzolamide is similar to sulfonamides, so an allergic reaction could occur. The other assessment findings are not related to brinzolamide.
A client is brought to the emergency department after a car crash. The client has a large piece of glass in the left eye. What action by the nurse takes priority?
a. Administer a tetanus booster shot.
b. Ensure the client has a patent airway.
c. Prepare to irrigate the clients eye.
d. Turn the client on the unaffected side.
b. Ensure the client has a patent airway.
Airway always comes first. After ensuring a patent airway and providing cervical spine precautions (do not turn the client to the side), the nurse provides other care that may include administering a tetanus shot. The clients eye may or may not be irrigated.
A nurse is seeing clients in the ophthalmology clinic. Which client should the nurse see first?
a. Client with intraocular pressure reading of 24 mm Hg
b. Client who has had cataract surgery and has worsening vision
c. Client whose red reflex is absent on ophthalmologic examination
d. Client with a tearing, reddened eye with exudate
b. Client who has had cataract surgery and has worsening vision
After cataract surgery, worsening vision indicates an infection or other complication. The nurse should see this client first. The intraocular pressure is slightly elevated. An absent red reflex may indicate cataracts. The client who has the tearing eye may have an infection.
The nurse working in the ophthalmology clinic sees clients with eyelid and eye problems. What information should the nurse understand about these disorders? (Select all that apply.)
a. A chalazion is an inflammation of an eyelid sebaceous gland.
b. An ectropion is the eyelid turning inward.
c. An entropion is the eyelid turning outward.
d. A hordeolum is an infection of the eyelid sweat gland.
e. Keratoconjunctivitis sicca is caused by drugs or diseases.
a. A chalazion is an inflammation of an eyelid sebaceous gland.
d. A hordeolum is an infection of the eyelid sweat gland.
e. Keratoconjunctivitis sicca is caused by drugs or diseases.
A chalazion is an inflammation of one of the sebaceous glands in the eyelid. A hordeolum is an infection of a sweat gland in the eyelid. Keratoconjunctivitis sicca can be caused by drugs or diseases. An ectropion is an outward turning and sagging eyelid, while an entropion is an inward turning of the eyelid.
