1. The function of the auditory ossicles is to:
Options:
o A. transmit the light reflex to the light cone.
o B. transform sound vibrations into mechanical waves for
the inner ear.
o C. to capture sound waves from the external ear for
transmission into the middle ear.
o D. to separate the inner ear from the middle ear.
Correct Answer: B. transform sound vibrations into
mechanical waves for the inner ear.
Rationale: The auditory ossicles (malleus, incus, stapes) are
three small bones in the middle ear. Their primary function is to
efficiently transmit and amplify sound vibrations from the tympanic
membrane to the oval window of the inner ear, transforming airborne
sound into mechanical waves in the fluid-filled cochlea.

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:
Options:
o A. an arrhythmia.
o B. a neurological condition.
o C. an inner ear infection.
o D. orthostatic hypotension.
Correct Answer: B. a neurological condition.
Rationale: Vertigo accompanied by bilateral diplopia
(double vision) and ataxia (unsteady gait) points to a central
neurological cause (e.g., brainstem or cerebellar lesion), not a
peripheral vestibular disorder. Inner ear issues typically cause
vertigo with tinnitus or hearing loss, not diplopia. Cardiovascular
causes present with lightheadedness, presyncope, or arrhythmia.
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:
Options:
o A. a pinguecula.

NR 509
o B. a chalazion.
o C. episcleritis.
o D. xanthelasma.
Correct Answer: D. xanthelasma.
Rationale: Xanthelasma are yellowish, well-circumscribed
plaques of cholesterol deposits commonly found on the medial aspect
of the eyelids. They can be associated with hyperlipidemia.
Pinguecula are on the conjunctiva, a chalazion is a nodule on the
eyelid itself, and episcleritis is inflammation.
4. Assessment of a patient’s visual acuity resulted in 20/200 using the
Snellen eye chart. This means that:
Options:
o A. at 200 feet the patient can read printed information
that a person with normal vision could read at 20 feet.
o B. at 20 feet the patient can read printed information that
a person with normal vision could read at 200 feet.
o C. the patient has normal visual acuity.
o D. the patient may not be able to read so he should be
tested with the picture or "E" eye charts.
Correct Answer: B. at 20 feet the patient can read printed
information that a person with normal vision could read at 200 feet.

NR 509
Rationale: A visual acuity of 20/200 means the patient must
stand at 20 feet to see what a person with normal (20/20) vision can
see at 200 feet. This meets the criterion for legal blindness when
present in the better eye with best correction.
5. Findings following assessment of a person's left eye gaze include
impaired movements when attempting to look upward, downward, or
inward. This condition is most consistent with:
Options:
o A. a conjugate gaze.
o B. left cranial nerve III (oculomotor) paralysis.
o C. cranial nerve IV (trochlear) paralysis.
o D. cranial nerve VI (abducens) paralysis.
Correct Answer: B. left cranial nerve III (oculomotor)
paralysis.
Rationale: Cranial Nerve III (Oculomotor) innervates the
superior, inferior, and medial rectus muscles, and the inferior oblique
muscle, which control upward, downward, and inward eye
movements, as well as pupil constriction and eyelid elevation.
Paralysis impairs these motions.
