Questions and CORRECT Answers
Dizziness vs. Vertigo - CORRECT ANSWER Dizzy - you are spinning
Vertigo - the world is spinning around you
What are the 5 parts of the Neurologic exam? - CORRECT ANSWER Mental status
Cranial Nerves
Motor
Sensory
Coordination/Gait
When assessing CN I why should we avoid noxious smells? - CORRECT
ANSWER Triggers CN V - Trigeminal N
In eye exam, which nerves are responsible for what? - CORRECT ANSWER CN II -
visual acuity, visual fields
CN II + III - pupillary exam
CN III, IV, VI - extraocular movements
When assessing vision acuity, what charts are used? - CORRECT ANSWER Snellen -
20 ft away - far vision, smallest line
Rosenbaum - 14" from face - near vision, smallest line
Record as numerator (distance) / denominator (average distance)
Max 2 errors before moving up
,What is the confrontation test? - CORRECT ANSWER checking visual fields - CN II -
peripheral vision seen when looking at a central point
Quadrants: Superior nasal + temporal, Inferior nasal + temporal
Light shown into the eye causes constriction of that eye, what is this known as? - CORRECT
ANSWER Direct response
Light shown into eye causes constriction of the contralateral eye, what is this known as? -
CORRECT ANSWER Consensual response
Near Reaction - CORRECT ANSWER examines CN II + III
Convergence - bilateral medial rectus muscle activation
Accommodation - increased convexity of lenses brings the object into focus (not visible to
examiner)
What are the important fiber types in CN III (Oculommotor)? - CORRECT
ANSWER GSE - levator palpabrae superior + all extraocular muscles, except LR + SO
GVE - parasympathetic to pupil constrictor + ciliary muscles for near vision
Horner's syndrome - CORRECT ANSWER interruption of the OSP -
Oculosympathetic pathway
-anhidrosis
-miosis
-ptosis
, Marcus Gunn Pupil - CORRECT ANSWER Afferent - ipsilateral direct response
(absent), ipsilateral consensual response (present)
Lesion to the optic nerve, retina, or eye - decreased sensitivity of the affected eye to light
EBM, most common pupillary defect -> pupils may dilate as the light appears dimmer
Argyll Robertson Pupil - CORRECT ANSWER light-near dissociation, ipsilateral
direct response (diminished), ipsilateral accomodation (present)
What 3 things must be assessed for complete assessment of the Trigeminal N? - CORRECT
ANSWER Sensory to all three branches
Motor - muscles of mastication
Corneal reflex (V1 of CN V + CN VII)
Corneal Reflex - CORRECT ANSWER touch cornea with cotton wisp from opposite
direction of gaze -> bilateral eyelids should close
requires functional CN V1 + V2
How may we assess the facial muscles for CN VII assessment? - CORRECT
ANSWER Bare teeth
Puff out cheeks w/ resistance
Wrinkle forehead
Close eyes tightly against forced opening
UMN lesion of the face - CORRECT ANSWER contralateral facial weakness
spares contralateral forehead
CVA - central palsy
