This document provides information on various eye, ear, and throat disorders including:
1. Strabismus (lazy eye) which results from muscle imbalance and can lead to vision loss if not treated early with corrective lenses, patching, Botox injections, or surgery.
2. Conjunctivitis (pink eye) which is usually caused by infection, allergy, or trauma and treated with antibiotics, antivirals, or antihistamines depending on the cause.
3. Otitis media (ear infection) which occurs when the eustachian tube becomes blocked, leading to fever and ear pain and treated with antibiotics, analgesics, and sometimes myringotomy tubes.
2. I. STRABISMUS
A. Description
1. Called “squint” or “lazy eye”
2. Condition in which the eyes are not aligned
because of lack of coordination of the
extraocular muscles
3. Most often results from muscle imbalance or
paralysis of extraocular muscles but also may
result from conditions such as a brain
tumor, myasthenia gravis, or infection
4. Normal in the young infant but should not be
present after about age 4 months
3. B. Assessment
1. Amblyopia (reduced visual acuity) if not
treated early
2. Permanent loss of vision if not treated early
3. Loss of binocular vision
4. Impairment of depth perception
5. Frequent headaches
6. Squinting or tilting of the head to see
4. C. Interventions
1. Corrective lenses may be indicated.
2. Instruct the parents regarding patching (occlusion therapy) of the
“good” eye to strengthen the weak eye.
3. Injection of botulinum toxin (Botox) may be prescribed (injected into
the eye muscle) as a nonsurgical intervention (treatment produces
temporary paralysis to allow the muscles opposite the paralyzed
muscle to
straighten the eye).
4. Inform the parents that the injection of botulinum toxin wears off in
about 2 months and, if successful, correction will occur.
5. Prepare for surgery to realign the weak muscles as prescribed if
nonsurgical interventions are unsuccessful; this is performed before
the age of 2 years.
6. Instruct the parents about the need for follow-up visits.
5. II. CONJUNCTIVITIS
A. Description
1. Also is known as “pinkeye”; is an inflammation
of the conjunctiva
2. Conjunctivitis usually is caused by
allergy, infection, or trauma.
3. Bacterial or viral conjunctivitis is extremely
contagious.
4. Chlamydial conjunctivitis is rare in older
children and, if diagnosed in a child who is not
sexually active, the child should be assessed for
possible sexual abuse.
7. C. Interventions
1. Instruct in infection control measures such as good hand washing and not
sharing towels and washcloths.

care until antibiotic eye drops have been administered for 24 hours.
6. Instruct about the use of cool compresses to lessen irritation and wearing
dark glasses for photophobia.
7. Instruct the child to avoid rubbing the eye to prevent injury.
8. Instruct the child who is wearing contact lenses to discontinue wearing
them and to obtain new lenses to eliminate the chance of reinfection.
9. Instruct the adolescent that eye makeup should be discarded and replaced.
8. III. OTITIS MEDIA
A. Description
1. Otitis media is an inflammatory disorder
usually caused by an infection of the middle ear
occurring as a result of a blocked eustachian
tube, which prevents normal drainage.
2. Otitis media is a common complication of an
acute respiratory infection.
3. Infants and children are more prone to otitis
media because their eustachian tubes are
shorter, wider, and straighter.
9. B. Assessment

membrane
10. C. Interventions
1. Encourage fluid intake.
2. Teach the parents to feed infants in upright position, to prevent reflux.
3. Instruct the child to avoid chewing as much as possible during the acute
period because chewing increases pain.
4. Provide local heat and have the child lie with the affected ear down.
5. Instruct the parents in the appropriate procedure to clean drainage from
the ear with sterile cotton swabs.
6. Instruct the parents in the administration of analgesics or antipyretics such
as acetaminophen (Tylenol) to decrease fever and pain.
7. Instruct the parents in the administration of the prescribed
antibiotics, emphasizing that the 10- to 14-day period is necessary to
eradicate infective organisms.
8. Instruct the parents that screening for hearing loss may be necessary.
9. Instruct the parents about the procedure for administering ear
medications.
11. Administration of Medications
• In a child younger than age 3, pull the lobe down and back.

cause nasal quality of
speech, mouth
breathing, hearing
difficulty, snoring, and/or
obstructive sleep apnea.
15. C. Preoperative interventions
1. Assess for signs of active infection.
2. Assess bleeding and clotting studies because
the throat is vascular.
3. Prepare the child for a sore throat
postoperatively, and inform the child that he
or she will need to drink liquids.
4. Assess for any loose teeth to decrease the risk
of aspiration during surgery.
16. D. Interventions postoperatively
1. Position the child prone or side-lying to facilitate drainage.
2. Have suction equipment available, but do not suction unless there is an airway
obstruction.
3. Monitor for signs of hemorrhage (frequent swallowing may indicate hemorrhage); if
hemorrhage occurs, turn the child to the side and notify the physician.
4. Discourage coughing or clearing the throat.
5. Provide clear, cool, noncitrus and noncarbonated fluids.
6. Avoid milk products initially because they will coat the throat.
7. Avoid red liquids, which simulate the appearance of blood if the child vomits.
8. Do not give the child any straws, forks, or sharp objects that can be put into the
mouth.
9. Administer acetaminophen (Tylenol) for sore throat as prescribed.
10. Instruct the parents to notify the physician if bleeding, persistent earache, or fever
occurs.
11. Instruct the parents to keep the child away from crowds until healing has occurred.
17. V. EPISTAXIS (NOSEBLEEDS)
A. Description
1. The nose, especially the septum, is a highly
vascular structure, and bleeding usually
results from direct trauma, foreign bodies, and
nose picking, or from mucosal inflammation.
2. Recurrent epistaxis and severe bleeding
may indicate an underlying disease.
18. B. Interventions
1. Have the child sit up and lean forward (not lying
down).
2. Apply continuous pressure to nose with the
thumb and forefinger for at least 10 minutes.
3. Insert cotton or wadded tissue into each
nostril, and apply ice or a cold cloth to the bridge
of the nose if bleeding persists.
4. Keep the child calm and quiet.
5. If bleeding cannot be controlled, packing or
cauterization of the bleeding vessel may be
prescribed.
19. Refractive Errors
1. Description
a. Refraction is the bending of light rays; any problem associated
with eye length or refraction can lead to refractive errors.
b. Myopia (nearsightedness): Refractive ability of the eye is too
strong for the eye length; images are bent and fall in front of, not
on, the retina.
c. Hyperopia (farsightedness): Refractive ability of the eye is too
weak; images are focused behind the retina.
d. Presbyopia: Loss of lens elasticity because of aging; less able to
focus the eye for close work and images fall behind the retina.
e. Astigmatism: Occurs because of the irregular curvature of the
cornea; image does not focus on the retina.
20. 2. Assessment
a. Refractive errors are diagnosed through a
process called refraction.
b. The client views an eye chart while various
lenses ofdifferent strengths are systematically
placed in front of the eye and is asked
whether the lenses sharpen or worsen the
vision.
21. 3. Nonsurgical interventions: Eyeglasses or
contact lenses
4. Surgical interventions
a. Radial keratotomy: Incisions are made
through the peripheral cornea to flatten the
cornea, which allows the image to be focused
closer to the retina; used to treat myopia.
22. Surgical interventions cont…
b. Photorefractive keratotomy: A laser beam is used to
remove small portions of the corneal surface to
reshape the cornea to focus an image properly on the
retina; used to treat myopia and astigmatism.
c. Laser-assisted in-situ keratomileusis (LASIK): The
superficial layers of the cornea are lifted as a flap, a
laser reshapes the deeper corneal layers, and then the
corneal flap is replaced; used to treat
hyperopia, myopia, and astigmatism.
d. Intacs corneal ring: The shape of the cornea is changed
by placing a flexible ring in the outer edges of the
cornea; used to treat myopia.
23. C. Legally blind

ground where the client's foot will be placed next
to determine the presence of obstacles.
26. D. Cataracts
1. Description
a. A cataract is an opacity of the
lens that distorts the image
projected onto the retina and
that can progress to blindness.
b. Causes include the aging
process (senile
cataracts), inherited (congenital
cataracts), and injury (traumatic
cataract s); cataract s also can
result from another eye disease
(secondary cataract s).
c. Intervention is indicated when
visual acuity has been reduced to
a level that the client finds to be
unacceptable or adversely affects
his or her lifestyle.
27. 2. Assessment
a. Blurred vision and decreased color
perception are early signs
b. Diplopia, reduced visual acuity, absence of
the red reflex, and the presence of a white
pupil are late signs. Pain or eye redness is

42. G. Macular degeneration
1. A deterioration of the macula, the area of central vision
2. Can be atrophic (age-related or dry) or exudative (wet)
3. Age-related: Caused by gradual blocking of retinal
capillaries leading to an ischemic and necrotic macula;
rods and cones photoreceptors die.
4. Exudative: Serous detachment of pigment epithelium
in the macula occurs; fluid and blood collect under the
macula, resulting in scar formation and visual
distortion.

a. Damage to the abducens and facial cranial nerves
b. Damage is exhibited by inability to look laterally
(cranial nerve VI, abducens) and a drooping of
the mouth on the affected side (cranial nerve
VII, facial).
c. Meningitis
d. Brain abscess
e. Chronic purulent otitis media
f. Wound infections
g. Vertigo, if the infection spreads into the labyrinth
74. 5. Postoperative interventions
a. Monitor for dizziness.
b. Monitor for signs of meningitis, as evidenced by a stiff neck and
vomiting.
c. Prepare for a wound dressing change 24 hours postoperatively.
d. Monitor the surgical incision for edema, drainage, and redness.
e. Position the client flat with the operative side up.
f. Restrict the client to bed with bedside commode privileges for 24
hours as prescribed.
g. Assist the client with getting out of bed to prevent falling or injuries
from dizziness.
h. With reconstruction of the ossicles via a graft, take precautions to
prevent dislodging of the graft.
75. M. Otosclerosis
1. Description
a. Otosclerosis is a disease of the labyrinthine capsule of the middle ear that results
in a bony overgrowth of the tissue surrounding the ossicles.
b. Otosclerosis causes the development of irregular areas of new bone formation and
causes the fixation of the bones.
c. Stapes fixation leads to a conductive hearing loss.
d. If the disease involves the inner ear, sensorineural hearing loss is present.
e. To have bilateral involvement is not uncommon, although hearing loss may be
worse in one ear.
f. The cause is unknown, although it is thought to have a familial tendency.
g. Nonsurgical intervention promotes the improvement of hearing through
amplification.
h. Surgical intervention involves removal of the bony growth causing the hearing loss.
i. A partial stapedectomy or complete stapedectomy with prosthesis (fenestration)
may be performed surgically.
76. 2. Assessment
a. Slowly progressing conductive hearing loss
b. Bilateral hearing loss
c. A ringing or roaring type of constant tinnitus
d. Loud sounds heard in the ear when chewing
e. Pinkish discoloration (Schwartze's sign) of the
tympanic membrane, which indicates vascular
changes within the ear.
f. Negative Rinne test
g. Weber's test shows lateralization of sound to the
ear with the most conductive hearing loss.
77. N. Fenestration
1. Description
a. Fenestration is removal of the stapes, with a
small hole drilled in the footplate; a prosthesis
is connected between the incus and footplate.
b. Sounds cause the prosthesis to vibrate in the
same manner as the stapes.
c. Complications include complete hearing
loss, prolonged vertigo, infection, or facial
nerve damage.
78. 2. Preoperative interventions
a. Instruct the client in measures to prevent
middle ear or external ear infections.
b. Instruct the client to avoid excessive nose
blowing.
c. Instruct the client not to clean the ear canal
with cotton-tipped applicators and to avoid
trauma or injury to the ear canal.
79. 3. Postoperative interventions
a. Inform the client that hearing is initially worse after the surgical procedure
because of swelling and that no noticeable improvement in hearing may
occur for as long as 6 weeks.
b. Inform the client that the Gelfoam ear packing interferes with hearing but
is used to decrease bleeding.
c. Assist with ambulating during the first 1 to 2 days after surgery.
d. Provide side rails when the client is in bed.
e. Administer antibiotic, antivertiginous, and pain medications as prescribed.
f. Assess for facial nerve damage, weakness, changes in tactile sensation and
taste sensation, vertigo, nausea, and vomiting.
g. Instruct the client to move the head slowly when changing positions to
prevent vertigo.
h. Instruct the client to avoid persons with upper respiratory tract infections.
80. i. Instruct the client to avoid showering and getting the
head and wound wet.
j. Instruct the client to avoid using small objects (cotton-
tipped applicators) to clean the external ear canal.
k. Instruct the client to avoid rapid extreme changes
inpressure caused by quick head
movements, sneezing, nose blowing, straining, and
changes in altitude.
l. Instruct the client to avoid changes in middle ear
pressure because they could dislodge the graft or
prosthesis.
81. O. Labyrinthitis
1. Description: Infection of the labyrinth that
occurs as a complication of acute or chronic
otitis media
2. May result from growth of a cholesteatoma—
benign overgrowth of squamous cell
epithelium
82. 3. Assessment
a. Hearing loss that may be permanent on the
affected side
b. Tinnitus
c. Spontaneous nystagmus to the affected side
d. Vertigo
e. Nausea and vomiting
83. 4. Interventions
a. Monitor for signs of meningitis, the most common
complication, as evidenced by headache, stiff neck, and
lethargy.
b. Administer systemic antibiotics as prescribed.
c. Advise the client to rest in bed in a darkened room.
d. Administer antiemetics and antivertiginous
medications as prescribed.
e. Instruct the client that the vertigo subsides as the
inflammation resolves.
f. Instruct the client that balance problems that persist
may require gait training through physical therapy.
84. P. Menière's syndrome
1. Description
a. Menière's syndrome is also called endolymphatic
hydrops; it refers to dilation of the endolymphatic system
by overproduction or decreased reabsorption of
endolymphatic fluid.
b. The syndrome is characterized by tinnitus, unilateral
sensorineural hearing loss, and vertigo.
c. Symptoms occur in attacks and last for several days, and
the client becomes totally incapacitated during the attacks.
d. Initial hearing loss is reversible but as the frequency of
attacks continues, hearing loss becomes permanent.
e. Repeated damage to the cochlea caused by increased
fluid pressure leads to permanent hearing loss.
85. 2. Causes
a. Any factor that increases endolymphatic
secretion in the labyrinth
b. Viral and bacterial infections
c. Allergic reactions
d. Biochemical disturbances
e. Vascular disturbance, producing changes in the
microcirculation in the labyrinth
f. Long-term stress may be a contributing factor.
86. 3. Assessment
a. Feelings of fullness in the ear
b. Tinnitus, as a continuous low-pitched roar or humming sound, that
is present much of the time but worsens just before and during
severe attacks
c. Hearing loss that is worse during an attack
d. Vertigo, as periods of whirling, that might cause the client to fall to
the ground
e. Vertigo that is so intense that even while lying down, the client
holds the bed or ground in an attempt to prevent the whirling
f. Nausea and vomiting
g. Nystagmus
h. Severe headaches
87. 4. Nonsurgical interventions
a. Prevent injury during vertigo attacks.
b. Provide bed rest in a quiet environment.
c. Provide assistance with walking.
d. Instruct the client to move the head slowly to prevent worsening of the
vertigo.
e. Initiate sodium and fluid restrictions as prescribed.
f. Instruct the client to stop smoking.
g. Administer nicotinic acid (niacin) as prescribed for its vasodilatory effect.
h. Administer antihistamines as prescribed to reduce the production of
histamine and the inflammation.
i. Administer antiemetics as prescribed.
j. Administer tranquilizers and sedatives as prescribed to calm the
client, allow the client to rest, and control vertigo, nausea, and vomiting.
k. Mild diuretics may be prescribed to decrease endolymph volume
88. 5. Surgical interventions
a. Surgery is performed when medical therapy is
ineffective and the functional level of the client
has decreased significantly.
b. Endolymphatic drainage and insertion of a shunt
may be performed early in the course of the
disease to assist with the drainage of excess
fluids.
c. A resection of the vestibular nerve or total
removal of the labyrinth or a labyrinthectomy
may be performed.
89. 6. Postoperative interventions
a. Assess packing and dressing on the ear.
b. Speak to the client on the side of the unaffected
ear.
c. Perform neurological assessments.
d. Maintain side rails.
e. Assist with ambulating.
f. Encourage the client to use a bedside commode
rather than ambulating to the bathroom.
g. Administer antivertiginous and antiemetic
medications as prescribed.
90. Trauma
1. Description
a. The tympanic membrane has a limited stretching ability and gives
way under high pressure.
b. Foreign objects placed in the external canal may exert pressure
on the tympanic membrane and cause perforation.
c. If the object continues through the canal, the bony structure of
the stapes, incus, and malleus may be damaged.
d. A blunt injury to the basal skull and ear can damage the middle
ear structures through fractures extending to the middle ear.
e. Excessive nose blowing and rapid changes of pressure that occur
with nonpressurized air flights can increase pressure in the middle
ear.
f. Depending on the damage to the ossicles, hearing loss may or
may not return.
91. 2. Interventions
a. Tympanic membrane perforations usually heal
within 24 hours.
b. Surgical reconstruction of the ossicles and
tympanic membrane through tympanoplasty
or myringoplasty may be performed to
improve hearing.
92. S. Cerumen and foreign bodies
1. Description
a. Cerumen, or wax, is the most common
cause of impacted canals.
b. Foreign bodies can include
vegetables, beads, pencil erasers, insects, and
other objects.
93. 2. Assessment
a. Sensation of fullness in the ear with or
without hearing loss
b. Pain, itching, or bleeding
94. 3. Cerumen
a. Removal of wax by irrigation is a slow process.
b. Irrigation is contraindicated in clients with a
history of tympanic membrane perforation or
otitis media.
c. To soften cerumen, add three drops of glycerin or
mineral oil to the ear at bedtime, and three drops
of hydrogen peroxide twice daily as prescribed.
d. After several days, irrigate the ear.
e. The maximum amount of solution that should be
used for irrigation is 50 to 70 mL.
95. 4. Foreign bodies
a. With a foreign object of vegetable
matter, irrigation is used with care because this
material expands with hydration.
b. Insects are killed before removal, unless they can
be coaxed out by flashlight or a humming noise.
c. Mineral oil or diluted alcohol is instilled to
suffocate the insect, which then is removed using
ear forceps.
d. Use a small ear forceps to remove the object and
avoid pushing the object farther into the canal
and damaging the tympanic membrane.
