Which statement describes the laser in situ keratomileusis (LASIK) surgery used to correct myopia?
-
- The cornea is reshaped by excision of a small piece of corneal tissue.Small incision lenticule extraction (SMILE) is a laser procedure in which the cornea is reshaped by excision of a small piece of corneal tissue.
-
- Pulsations of ultraviolet (UV) light on the central superficial tissue reshape the cornea.The LASIK procedure does not use UV light.
- Correct
- The middle layer of the cornea is reshaped with a laser after a very thin outer layer of the cornea is peeled back.With LASIK, the middle layer of the cornea is reshaped with a laser after a very thin outer layer of the cornea is peeled back.
-
- An excimer laser is used to remove a thin layer of tissue from the cornea.In photorefractive keratectomy (PRK), an excimer laser is used to remove a thin layer of tissue from the cornea.
Question 2 of 10

The nurse suspects which reason for a 66-year-old patient’s inability to see objects that are nearby as well as objects that are at a distance?
-
- Hardening of the corneaHardening of the cornea does not present as loss of near and far vision.
-
- Decreased eye perfusionDecreased eye perfusion does not present as loss of near and far vision.
- Correct
- Hardening of the ciliary musclesHardening of the ciliary muscles (presbyopia) occurs in many people older than 40 years. With increasing age, the ciliary muscles become less elastic and cannot readily accommodate the needs of distant and near vision.
-
- Increased ocular pressureIncreased ocular pressure is a symptom of glaucoma.
Question 3 of 10
Report content error
The nurse suspects which eye condition in a patient with a recent history of West Nile virus who presents with a small, nonreactive irregular pupil?
-
- GlaucomaPupil changes are not associated with glaucoma. Glaucoma involves increased intraocular pressure.
- Correct
- UveitisWest Nile virus has been implicated as a cause of uveitis. Symptoms include a small, nonreactive, irregular pupil.
-
- CataractPupil changes are not associated with cataracts.
-
- PresbyopiaPupil changes are not associated with presbyopia.
Question 4 of 10
Report content error
Which explanation would the nurse give to a 55-year-old patient who asks why bifocal lenses have been prescribed?
-
- With aging, the eyeball becomes shortened, causing difficulty seeing objects at a distance.If the eyeball is too elongated, the patient will have difficulty seeing objects at a distance.
-
- Aging causes changes in the shape of a cornea.Irregular curvature of the cornea occurs, causing astigmatism; bifocals do not correct this problem.
-
- Cataracts may develop with aging.Cataracts may develop because of aging; however, bifocal lenses do not correct cataracts.
- Correct
- Both near and far vision become more difficult with aging.Bifocal eyeglasses are usually prescribed for presbyopia (age-related eye changes) because they allow for one set of lenses for viewing distant objects and one for seeing close objects.
Question 5 of 10
Report content error
Which education about the laser in situ keratomileusis (LASIK) procedure would the nurse provide to a patient who voices concern about postoperative pain?
-
- “This procedure may create significant discomfort, but you will be provided with eye drops to control the pain.”LASIK does not usually cause significant pain; pain relief eye drops would not likely be administered.
- Correct
- “Typically, this procedure produces very little discomfort.”Postoperative recovery with LASIK is very rapid with little discomfort.
-
- “You will be premedicated with morphine to control pain.”Premedication with morphine is not typically necessary for the LASIK procedure.
-
- “You shouldn’t worry about pain. We will take good care of you.”Telling the patient not to worry is not therapeutic. The nurse should provide an explanation regarding the level of pain the patient may expect.
Question 6 of 10
Report content error
The nurse would provide which rationale for why artificial tears have been prescribed to a patient with exophthalmos?
-
- To improve visionArtificial tears will not correct visual defects.
-
- To treat decreased tear productionExophthalmos does not decrease tear production.
- Correct
- To prevent corneal irritationPatients with exophthalmos may develop keratitis, which is inflammation of the cornea caused by irritation or infection. Treatment of irritation is instillation of artificial tears.
-
- To promote blinkingArtificial tears do not promote blinking.
Question 7 of 10
Report content error
The nurse expects to find which intervention on the plan of care for a patient with a corneal ulcer who has no history of injury?
-
- KeratoplastyKeratoplasty would not be prescribed at this time. Scarring from corneal ulcers or severe infection is treated by keratoplasty.
-
- Further eye imagingFurther imaging is not indicated because it is already known that the corneal ulcer exists.
-
- Referral for a laser in situ keratomileusis (LASIK) procedureThe LASIK procedure may be used to treat visual defects, but it is not indicated for corneal ulcers.
- Correct
- CultureThe ulcer is cultured to determine whether there is a causative organism when there is no history of injury.
Question 8 of 10
Report content error
Which nursing response is appropriate when a patient asks about the waiting period to receive a corneal transplant?
-
- “You will be scheduled for the procedure immediately.”The procedure cannot be scheduled until there is a donor available.
-
- “Extension preoperative testing needs to be completed first. Soon thereafter, you will be scheduled for the surgery.”The procedure cannot be scheduled until there is a donor available.
- Correct
- “Donor availability can be unpredictable. We may have to contact you on short notice.”The patient must understand that it is difficult to predict when a donor cornea will become available, and therefore the procedure may be set up on short notice.
-
- “You will not be eligible for the procedure until there is a total loss of vision.”Complete loss of vision is not necessary to qualify for the procedure.
Question 9 of 10
Report content error
Which action would the nurse take when a patient who is recovering from cataract surgery reports a headache in the brow area?
-
- Continue to monitor the patient.A brow headache may be an indication of increased intraocular pressure; the nurse needs to take immediate action.
-
- Provide ice packs to decrease discomfort.Providing ice packs does not address the potential issue of increasing intraocular pressure.
-
- Immediately lower the head of the bead.The patient may be experiencing increased intraocular pressure. Lowering the head of the bed would increase the pressure and worsen the problem.
- Correct
- Report this finding to the surgeon immediately.The surgeon should be notified immediately because this may indicate increasing intraocular pressure.
Question 10 of 10
Report content error
The nurse would observe for which sign of complications when providing care to a patient after enucleation surgery? Select all that apply. One, some, or all responses may be correct.
-
- Excessive tear productionExcessive tear production is not a symptom of complications after enucleation.
-
- PresbyopiaPresbyopia is farsightedness and not related to enucleation.
- Correct
- Elevated temperaturePostoperatively, the nurse would observe for signs of complications such as elevated temperature.
- Correct
- Excessive bleedingPostoperatively, the nurse would observe for signs of complications such as excessive bleeding.
- Correct
- SwellingPostoperatively, the nurse would observe for signs of complications such as swelling.
-
- HypertensionHypertension is not a complication associated with enucleation.
