NR 509 APEA EXAM - HEENT Question 1
The function of the auditory ossicles is to:
a) Transmit the light reflex to the light cone.
b)
... [Show More] Transform sound vibrations into mechanical waves for the inner ear: Correct
c) To capture sound waves from the external ear for transmission into the middle
ear.
d) 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
Question 2
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:
a) an arrhythmia.
b) a neurological condition: Correct
c) an inner ear infection. Incorrect
d) 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.
Question 3
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:
a) a pinguecula.
b) a chalazion.
c) episcleritis.
d) xanthelasma. Correct
Explanation:
Slightly raised, yellowish, well-circumscribed plaques appearing along the nasal area of
one or both eyelids are consistent with lipid disorders and called xanthelasma.
Pinguecula refer to harmless, yellowish, triangular nodules in the bulbar conjunctiva on
either side of the iris. A chalazion is a nontender nodule usually on the underside of the
eyelid. Episcleritis is an ocular inflammation of the episcleral vessels.
Question 4
Assessment of a patient's visual acuity resulted in 20/200 using the Snellen eye chart.
This means that:
a) at 200 feet the patient can read printed information that a person with normal
vision could read at 20 feet.
b) at 20 feet the patient can read printed information that a person with normal
vision could read at 200 feet: Correct
c) the patient has normal visual acuity.
d) the patient may not be able to read so he should be tested with the picture or "E"
eye charts.
Explanation:
Visual acuity that is corrected to 20/200 constitutes legal blindness. The larger the
number under 20, the worse the visual acuity. If this is a new finding, the patient needs
ophthalmologic evaluation. [Show Less]
