NR 509 Final Exam
1.Question:
The function of the auditory ossicles is to:
transmit the light reflex to the light cone.
transform sound vibrations into mechanical waves for the inner ear.
to capture sound waves from the external ear for transmission into the middle ear.
to separate the inner ear from the middle ear.
Explanation:
The function of the auditory ossicles is to transform sound vibrations into mechanical
waves for the inner ear
2.Question:
A 35-year-old patient complains of vertigo accompanied by nausea and vomiting.
Examination reveals bilateral diplopia and an unsteady gait. These symptoms could
be suggestive of:
Anarrhythmia
.a neurological condition
, .an inner ear infection.
orthostatic hypotension.
Explanation:
Vertigo symptoms associated with neurologic conditions include: ataxia, diplopia,
and dysarthria. Symptoms associated with cardiovascular conditions and vertigo
include arrhythmias, orthostatic hypotension, vasovagal stimulation,
lightheadedness, weakness, or presyncope.
3.Question:
A 60-year-old was concerned about a yellowish colored lesion above her right eyelid.
Findings revealed a slightly raised yellowish, well circumscribed plaque along the
nasal area of her right eyelid. This finding is most consistent with:
apinguecula.
achalazion.
episcleritis.
xanthelasma.
