NUR 350 Chap 21 Review Questions and
Correct Answers
A patient has undergone cataract surgery. What nursing interventions help to prevent
postoperative complications?
Antiviral medications are given to prevent infections.
Teach the patient to instill medicine following aseptic techniques.
Teach the patient about proper hygiene and eye care techniques.
Ask the patient to discontinue all prescribed medicine two days after surgery.
Advise the patient to avoid actions that can cause increased intraocular pressure.
✅Teach the patient to instill medicine following aseptic techniques.
Teach the patient about proper hygiene and eye care techniques.
Advise the patient to avoid actions that can cause increased intraocular pressure.
Postoperative care of the eye is essential for proper wound healing. Increased
intraocular pressure may break the sutures and increases the risk of complications;
therefore, it should be prevented. Proper hygiene and eye care techniques prevent
contamination of the wound. Medicines should be instilled in the eye using aseptic
techniques to prevent infection. The full course of medicine should be completed to
obtain the therapeutic effect. Antibiotic drops, not antiviral medications, are given to
prevent infections.

A patient informs the nurse that he or she is using a homemade saline solution to store
contact lenses but is now having irritation and soreness. The nurse assesses
inflammation of the cornea. On what medication does the nurse anticipate educating the
patient?
,Inflammation of the cornea indicates keratitis. Acanthamoeba keratitis is caused by a
parasite that is associated with contact lens wear. Patients who use homemade saline
solution are more susceptible to Acanthamoeba contamination. This organism is
resistant to most drugs, and polyhexamethylene biguanide is an approved antifungal
eye drop. Tropicamide is given during the preoperative phase to produce pupillary
dilation. Besifloxacin is beneficial to a patient who has acute bacterial conjunctivitis.
Acetazolamide decreases the aqueous humor production and is beneficial to a patient
with glaucoma.

A patient presents with a sty in the left eye. Which nursing actions are appropriate to
manage the patient's condition?
Teach the patient to perform lid scrubs daily.
Prepare the patient for surgical removal of the sty.
Administer appropriate antibiotic ointments or drops, as prescribed.
Teach the patient to gently cleanse the lid margins with baby shampoo.
Instruct the patient to apply warm, moist compresses at least four times a day. ✅Teach
the patient to perform lid scrubs daily.
Administer appropriate antibiotic ointments or drops, as prescribed.
Instruct the patient to apply warm, moist compresses at least four times a day.
A sty, also called a hordeolum, is caused by a Staphylococcus aureus infection of the
sebaceous glands in the lid margin. The infection is manifested as a red, swollen,
circumscribed, and acutely tender area. The patient should be instructed to apply warm,
moist compresses at least four times a day to decrease the swelling and tenderness.
Lid scrubs should be performed daily. Infection should be treated with appropriate
antibiotic ointments or drops, as prescribed. Surgical intervention may not be required
because a sty may subside with basic interventions. Cleansing with baby shampoo is
not required because there are no secretions or crusting.

The nurse is assessing four patients with visual problems. Which patient does the nurse
determine is exhibiting signs of retinal detachment? ✅Patient A
Retinal detachment is a separation of the sensory retina and the underlying pigment
epithelium, with fluid accumulation between the two layers. Patients with a detaching
retina describe symptoms that include a "cobweb," "hairnet," or ring in the field of vision.
, Therefore the nurse will expect that Patient A has retinal detachment. For Patient B,
abnormal color perception and glares indicate cataracts. Redness, photophobia, and
foreign body sensation indicates epidemic keratoconjunctivitis for Patient C. Itching,
burning, redness, and tearing indicate allergic conjunctivitis in Patient D.
pp. 376- 377
Which visual problem will the nurse suspect in the patient who has symptoms of itching,
irritation, intolerance towards light, with crusts on the lid margins and lashes?
Cataract
Blepharitis
Retinal detachment
Allergic conjunctivitis ✅Blepharitis
Blepharitis is a common chronic bilateral inflammation of the lid margins associated with
crusts on the lid margins. Blepharitis is also associated with itching, irritation, and
photophobia. Cataract is a clouding of the lens in the eye, which affects vision by
abnormal color perception and glaring. Retinal detachment is a separation of the
sensory retina and the underlying pigment epithelium. The symptoms of retinal
detachment are photopsia and seeing a ring or cobwebs in the field of vision. Allergic
conjunctivitis is caused by exposure to an allergen and is associated with itching and
swelling.
pp. 370- 371
A patient is discharged to home after cataract surgery. What is the most important
instruction the nurse should include in the discharge teaching?
Restrict activity at home.
Wear a nighttime eye shield.
Do not bend, stoop, cough, or lift.
Wash hands before touching the eye. ✅Do not bend, stoop, cough, or lift.
When teaching postoperative home care for cataract surgery, the nurse should instruct
the patient to avoid activities such as bending, stooping, coughing, or lifting because
these activities can raise the intraocular pressure, which in turn can adversely affect the
newly implanted lens. All other activities are permissible. Wearing a nighttime eye shield
is not necessary. Washing hands before touching the eye is a general hygiene practice
and not specific to postoperative care.
