1. A 45-year-old patient presents with acute onset of double vision and
difficulty walking in a straight line. Which cranial nerve is most likely
involved based on these symptoms?
A) Cranial Nerve III
B) Cranial Nerve IV
C) Cranial Nerve VI
D) Cranial Nerve VIII
Answer: D) Cranial Nerve VIII
Explanation: The vestibular branch of Cranial Nerve VIII
(vestibulocochlear) is responsible for balance and spatial orientation.
Dysfunction can produce vertigo, nystagmus, and ataxia, leading to
symptoms of double vision (from nystagmus) and difficulty walking
straight. While CN III, IV, and VI control extraocular movements,
isolated diplopia without other oculomotor deficits points more toward
vestibular dysfunction.

2. During a neurological examination, a patient is unable to elevate,
adduct, or depress the eye when directed. The pupil is dilated and non-
reactive. Which cranial nerve is affected?
A) Oculomotor (CN III)
B) Trochlear (CN IV)
C) Abducens (CN VI)
D) Optic (CN II)
Answer: A) Oculomotor (CN III)
Explanation: The oculomotor nerve innervates the medial rectus,
superior rectus, inferior rectus, and inferior oblique muscles, as well as
the levator palpebrae superioris and the pupillary sphincter. A complete
CN III palsy results in the eye being "down and out," with ptosis,
diplopia, and a dilated, unreactive pupil if parasympathetic fibers are
involved.
3. A patient complains of an inability to taste food on the anterior two-
thirds of the tongue and decreased salivation. Which cranial nerve is
most likely damaged?
A) Cranial Nerve V
B) Cranial Nerve VII
C) Cranial Nerve IX
D) Cranial Nerve XII
Answer: B) Cranial Nerve VII
,3|Page
Explanation: The facial nerve (CN VII) provides taste sensation to the
anterior two-thirds of the tongue via the chorda tympani branch and
parasympathetic fibers to the submandibular and sublingual glands for
salivation. Damage to CN VII would impair these functions, while CN IX
supplies taste to the posterior one-third of the tongue.
4. A patient presents with deviation of the uvula to the left side upon
phonation, and the gag reflex is absent on the right. Which cranial
nerve is likely affected?
A) Cranial Nerve IX
B) Cranial Nerve X
C) Cranial Nerve XI
D) Cranial Nerve XII
Answer: B) Cranial Nerve X
Explanation: The vagus nerve (CN X) innervates the pharyngeal and
laryngeal muscles, including the levator veli palatini muscle. Unilateral
vagal nerve palsy causes the uvula to deviate away from the affected
side. The glossopharyngeal nerve (CN IX) also contributes to the gag
reflex; however, the asymmetrical uvular deviation is a classic sign of CN
X dysfunction.
5. A 60-year-old patient with a history of hypertension presents with
acute onset of hoarseness, dysphagia, and deviation of the tongue to
the left upon protrusion. Which cranial nerves are likely affected?
A) CN IX, X, XI
, 4|Page
B) CN X, XI, XII
C) CN IX, X, XII
D) CN VII, IX, X
Answer: C) CN IX, X, XII
Explanation: This constellation of symptoms is consistent with a bulbar
palsy affecting multiple lower cranial nerves. Hoarseness and dysphagia
suggest CN IX and X involvement; tongue deviation to the left indicates
a right-sided CN XII lesion. CN XI would cause sternocleidomastoid and
trapezius weakness, not tongue deviation.
6. Which of the following cranial nerves carries general somatic afferent
fibers but does NOT have a motor component?
A) Cranial Nerve V
B) Cranial Nerve VII
C) Cranial Nerve IX
D) Cranial Nerve II
Answer: D) Cranial Nerve II
Explanation: The optic nerve (CN II) is purely sensory, transmitting visual
information from the retina to the brain. It has no motor function. CN V,
VII, and IX all have both sensory and motor components.
