Which structure is found in the inner ear?
1
Auricle
2
Eardrum
3
Auditory canal
4
Semicircular canals - 4
Semicircular canals
The inner ear is composed of semicircular canals that are associated with the cochlea and
supplied by several nerves. The nerves associated with the inner ear are the vestibular, facial, and
cochlear nerves. The auricle, eardrum, and auditory canal are not structures of the inner ear. The
auricle, or pinna, is part of the external region of the ear. The eardrum is a structure found in the
middle region of the ear. The auditory canal forms the middle region of the ear.
A patient is complaining of excessive earwax, leading to diminished hearing ability. The nurse
will expect to teach the patient to administer which medication to correct this problem?
1
Pramoxine
2
Acetic acid
3
Hydrocortisone
4
Carbamide peroxide - 4
Carbamide peroxide
Carbamide peroxide works to soften earwax for easy removal while providing a weak
antibacterial action to prevent infection. Pramoxine, acetic acid, and hydrocortisone are not used
for excessive ear wax.
Which disorder can likely cause damage to the eustachian canal?
1
Psoriasis
2
Seborrhea
3
Otitis media
, 4
Otitis externa - 3
Otitis media
Otitis media is a common disorder in infants. The disease is characterized by fever and pain in
the ear, and in chronic conditions, severe infection in the ear cavity. The condition commonly
damages the eustachian canal because the initial stage of infection is confined to the middle ear.
Psoriasis, seborrhea, and otitis externa are not conditions observed in the eustachian tube.
Psoriasis and seborrhea are skin disorders that affect the external ear. Otitis externa is a common
disorder of the outer ear.
The nurse is caring for a patient who has a middle ear infection due to exposure to contaminated
water. The laboratory reports confirm fungal infection. Which is the drug of choice for treating
this condition?
1
Carbamide peroxide
2
Ofloxacin solution
3
Acetic acid and hydrocortisone solution
4
Neomycin, polymyxin B sulfates, and hydrocortisone solution - 3
Acetic acid and hydrocortisone solution
Otitis externa is a microbial infection of the ear canal or tympanum seen mostly in adults. The
condition is caused by exposure to contaminated water and results in itching and inflammation of
the external ear or auditory canal. Acetic acid and hydrocortisone solution is the choice of drug
for treating otitis media related to fungal infections. The drug is composed of hydrocortisone
(1%), acetic acid (2%), propylene glycol diacetate (3%), sodium acetate (0.015%), and
benzethonium chloride (0.02%). Acetic acid and hydrocortisone solution is effective for treating
itching and pain due to otitis externa, and it promotes comfort in patients. Carbamide peroxide,
ofloxacin solution, and Neomycin, polymyxin B sulfates, and hydrocortisone solution are not
used for treating fungus-related otitis externa. Carbamide peroxide is an earwax emulsifier used
to soften earwax. Ofloxacin solution and Neomycin, polymyxin B sulfates, and hydrocortisone
solution are the drugs used for treating bacterial-related otitis externa.
The nurse is caring for a child who is experiencing severe discomfort and high fever. The health
care provider diagnoses acute otitis media. Which first-line drug will be included as part of the
treatment plan?
1
Ofloxacin
2
Amoxicillin
