Question 1
How many teeth do adults have?
A) 28
B) 30
C) 32
D) 34
Correct Answer: C) 32
Rationale: Adults typically have 32 permanent teeth, including 8 incisors, 4
canines, 8 premolars, and 12 molars (including 4 wisdom teeth).
Question 2
Angular cheilosis/cheilitis is inflammation at the corners of the mouth caused by:
A) Vitamin C deficiency and bacterial infection
B) B vitamin deficiency and fungal infection
C) Iron deficiency and viral infection
D) Calcium deficiency and parasitic infection
Correct Answer: B) B vitamin deficiency and fungal infection
Rationale: Angular cheilosis is inflammation at the corners of the mouth caused by
B vitamin deficiency or fungal infection. It presents as cracking, fissuring, and
redness at the oral commissures.
,Question 3
If the tongue deviates to the right when you stick it out, which nerve is damaged?
A) Left hypoglossal nerve (CN XII)
B) Right hypoglossal nerve (CN XII)
C) Left vagus nerve (CN X)
D) Right glossopharyngeal nerve (CN IX)
Correct Answer: B) Right hypoglossal nerve (CN XII)
Rationale: Tongue muscles PUSH, so the tongue is pushed by the normal side
toward the side of the lesion. If the tongue deviates to the right, the right
hypoglossal nerve is damaged, and the left (normal) side pushes the tongue to the
right.
Question 4
Papilledema is characterized by:
A) Yellowing of the sclera
B) Blurring or increased cupping of the optic disc, inflammation, and
hemorrhaging of vessels
C) Clouding of the lens
D) Increased intraocular pressure
Correct Answer: B) Blurring or increased cupping of the optic disc,
inflammation, and hemorrhaging of vessels
Rationale: Papilledema is swelling of the optic disc due to increased intracranial
pressure. Findings include blurred disc margins, optic disc hyperemia, venous
engorgement, and hemorrhages around the disc.
Question 5
Which three cranial nerves are responsible for extraocular movements (EOM)?
,A) CN II, III, IV
B) CN III, IV, VI
C) CN III, V, VI
D) CN IV, V, VI
Correct Answer: B) CN III, IV, VI
Rationale: Cranial nerves III (Oculomotor), IV (Trochlear), and VI (Abducens)
control extraocular movements. CN III controls most EOM plus pupillary
constriction and lid elevation; CN IV controls downward and internal rotation; CN
VI controls lateral deviation.
Question 6
A macule is best described as:
A) A raised, solid lesion <1 cm
B) A flat, fluid-filled lesion >1 cm
C) A flat lesion <1 cm that is usually round
D) A raised, fluid-filled lesion <0.5 cm
Correct Answer: C) A flat lesion <1 cm that is usually round
Rationale: A macule is a primary lesion that is flat, <1 cm, usually round, and can
be brown, white, or red. Examples include freckles and moles.
Question 7
A patch is characterized as:
A) A flat lesion >1 cm with irregular shape
B) A raised lesion >1 cm
C) A flat lesion <1 cm
D) A fluid-filled lesion >1 cm
Correct Answer: A) A flat lesion >1 cm with irregular shape
, Rationale: A patch is a primary lesion that is flat, >1 cm, irregular in shape, and
can be blue, brown, red, or have absence of pigment. Examples include vitiligo and
café au lait spots.
Question 8
Damage to upper motor neurons (brain and spinal cord) will present:
A) Ipsilateral to the damage
B) Contralateral to the damage
C) Bilaterally
D) Only in the lower extremities
Correct Answer: B) Contralateral to the damage
Rationale: Upper motor neuron lesions (in the brain or spinal cord) result in
weakness or paralysis on the contralateral (opposite) side of the body due to the
decussation (crossing) of motor pathways in the brainstem.
Question 9
Damage to lower motor neurons will present:
A) Contralateral to the damage
B) Bilaterally
C) Ipsilateral to the damage
D) Only in the face
Correct Answer: C) Ipsilateral to the damage
Rationale: Lower motor neuron lesions result in weakness or paralysis on the
ipsilateral (same) side of the body because the cell bodies of lower motor neurons
are located in the anterior horn of the spinal cord and their axons travel directly to
muscles without crossing.
Question 10
