Health Assessment: ENT Test BankQuestions
The middle ear contains the:
a. cerumen and sebaceous glands.
b.umbo and malleus.
c.vestibule and cochlea.
d.pars tensa and semicircular canals. - ANSB
The middle ear contains the ossicles, three small bones—the malleus (umbo is part of the
malleus), the incus, and the stapes. Cerumen and sebaceous glands lie outside the middle ear.
The vestibule and the cochlea lie in the inner ear. The tympanic membrane separates the
external ear from the middle ear and is composed of the pars tensa, and the semicircular canals
lie in the inner ear.
The middle ear is normally filled with:
a.air.
b.blood.
c.serous fluid.
d.cerebrospinal fluid. - ANSA
The middle ear normally is an air-filled cavity in the temporal bone.
The hair cells of Corti and membrane of Corti:
a.produce a waxy lubricant.
b.protect the ear from foreign particles.
c.stimulate the eighth cranial nerve.
d.transmit vibrations to the ossicles. - ANSC
Vibrations from the tympanic membrane cause the delicate hair cells of the organ of Corti to
strike against the membrane of Corti, stimulating impulses in the sensory endings of the
auditory division of the eighth cranial nerve.
The organ of Corti is a coiled structure located inside the:
a.cochlea in the inner ear.
b.pars flaccida in the tympanic membrane.
c.eustachian tube.
d.lateral aspect of the pinna. - ANSA
The cochlea is a coiled structure within the inner ear that contains the organ of Corti.
, Mrs. Kinder is a 39-year-old patient who presents to the office with complaints of an earache. In
explaining to the patient about the function of her ears, which ear structure would you tell her is
responsible for equalizing atmospheric pressure when swallowing, sneezing, or yawning?
a.Eustachian tube
b.Inner ear
c.Pars flaccida
d.Triangular fossa - ANSA
The eustachian tube is a cartilaginous and bony passageway between the nasopharynx and
middle ear that opens briefly to equalize the middle ear pressure with that of the atmospheric
pressure when swallowing, yawning, or sneezing.
Mr. Sprat is a 21-year-old patient who complains of nasal congestion. He admits to using
recreational drugs. On examination, you have noted a septal perforation. Which of the following
recreational drugs is commonly associated with nasal septum perforation?
a.Heroin
b.Cocaine
c.PCP
d.Ecstasy - ANSB
Long-term cocaine snorting causes ischemic necrosis of the septal cartilage and leads to
perforation of the nasal septum.
A 5-year-old child presents with nasal congestion and a headache. To assess for sinus
tenderness, you should palpate over the:
a.sphenoid and frontal sinuses.
b.maxillary and frontal sinuses.
c.maxillary sinuses only.
d.sphenoid sinuses only. - ANSC
Only the maxillary and the frontal sinuses are accessible for physical examination; however, the
young child does not develop frontal sinuses until 7 to 8 years of age.
An infant's auditory canal, compared with an adult's, is:
a.short, narrow, and straight.
b.short and curved upward.
c.long, narrow, and curved forward.
d.short and curved downward. - ANSB
Compared with the adult's, the infant's auditory canal is shorter and has an upward curve, which
is why pulling the pinna down straightens the canal.
