NEURO USAHS TEST GUIDE
QUESTIONS WITH COMPLETE
SOLUTIONS
Broca's aphasia - ANSWER -condition resulting from damage to Broca's area, causing
the affected person to be unable to speak fluently, to mispronounce words, and to
speak haltingly
Broca's area - ANSWER -Controls language expression - an area of the frontal lobe,
usually in the left hemisphere, that directs the muscle movements involved in speech.
CN 1 olfactory - ANSWER -Test: Making client smell something pleasant
What is being tested: imbalances in neurotransmitter systems, -nasal construction,
damage to olfactory nerves, lesions affecting olfactory bulbs
front of brain
CN II optic - ANSWER -Test: Examine both retinas with an ophthalmoscope. thalamus -
test visual acuity (Snellen chart, or # of fingers),
Test color vision- red desaturation
Test visual fields- report when a finger can be seen moving
Test Visual extinction- how many fingers they see
What is being tested: vision
retinas, damage to the visual cortex, deficits in visual fields of eyes
front of brain
CN III Oculomotor - ANSWER -thalamus - looking up, in, and left to right without moving
head
Test: extraocular movements- looking all directions without moving head, and ask if they
see double vision
What is being tested: abnormalities in muscles or CN III-oculomotor, IV-trochlear, VI-
abducens), deficits of the brainstem and cortex that control eye movements
midbrain structure
CN IV Trochlear - ANSWER -Test: extraocular movements- looking all directions
without moving head, and ask if they see double vision
What is being tested: extraocular movements (eye movements)
, -abnormalities in muscles or CN III-oculomotor, IV-trochlear, VI-abducens), deficits of
the brainstem and cortex that control eye movements
is a midbrain structure - cross-eyes into the nose
CN V Trigeminal - ANSWER -pons - - Dull vs light sensation in Ophthalmic (forehead)
Maxillary (Cheek)Mandibular (Jawline)
- Have the patient open and close mouth (feel around the temporomandibular joint)
-Corneal reflex
-Jaw jerk reflex
What is being tested: facial sensation and muscles of mastication
-Deficits/lesions of the trigeminal nerve or trigeminal sensory nuclei in the brainstem
pons
CN VI Abducens - ANSWER -looking laterally (left and right)
What is being tested: Extraocular movement -eye movement
- abnormalities in muscles or CN III-oculomotor, IV-trochlear, VI-abducens), deficits of
the brainstem and cortex that control eye movements
pons
CN VII Facial - ANSWER -controls most facial expressions
secretion of tears & saliva
taste
What is being tested: facial expressions (facial weakness) and taste (lesions in lateral
medulla -nucleus solitarius or facial nerve)
pons - Test facial symmetry - Taste on anterior 2/3 of the tongue (lateral aspect side of
the tongue)
smile - wrinkle forehead
CN VIII Vestibulocochlear - ANSWER -Test: Whisper test - Rinne Test - Weber Test,
hearing and equilibrium
What is being tested: hearing and vestibular sense
-hearing loss
pons (acoustic)
