C)Considered part of the central nervous system
D)Nerves from the brainstem that can innervate distal limb musculature

Answer 1

B

Question 2

If there is a unilateral CN IX/X deficit…

A)As the soft palate rises during "Ahhh",the uvula deviates toward the affected side
B)The uvula remains in the midline as the affected side of the soft palate rises
C)As the soft palate rises during "Ahhh",the uvula deviates toward the unaffected side
D)The uvula does not rise as the soft palate rises

Answer 2

C

Question 3

During the Weber Test to detect sensorineural hearing loss…

A)With tuning fork midline on top of the skull,the vibration seems louder in the unaffected ear
B)The tuning fork placed behind the ear,and air conduction lasts longer than bone conduction
C)With tuning fork midline on top of the skull,air conduction lasts longer than bone conduction
D)With the tuning fork placed behind the ear,the vibration seems louder in the ipsilateral ear

Answer 3

A

Question 4

Which of the following could result from a dysfunction of cranial nerve (CN) IV?

A)Inability to abduct the eye
B)Homonomous hemianopsia
C)Visual field deficit
D)Diplopia

Question 5

If there is unilateral weakness/paralysis of the tongue following CVA,which statement explains why the protruding tongue deviates to the affected side?

A)The affected side of the tongues moves further forward than the unaffected side of the tongue
B)The affected side of the tongue does not translate forward,whereas the unaffected side does movement forward
C)Both sides of the tongue translate forward but the affected side is stiff and immobile
D)The stiff tongue on the affected side prevents both sides from moving forward

Question 6

The facial motor characteristics that result from a right cerebral CVA include:

A)Facial paralysis of the left side of the forehead and face
B)Ptosis on the right side of the face
C)Facial paralysis of the left side of the face more than forehead
D)Droopy corner of the mouth on the right side

Question 7

The inability to elevate the eyelid on one side,termed ptosis,with a droopy eyelid is related to…

A)Dysfunction of CN III
B)Dysfunction of CN VII
C)Dysfunction of CN IV
D)Dysfunction of CN V

Question 8

A)Temporal homonomous hemianopsia
B)Right homonomous hemianopsia
C)Bitemporal hemianopsia
D)Hemianopsia resulting from right cerebrovascular accident (CVA)

Question 9

Which is true of the ocular movement examination?

A)It is testing for CN III,IV,and V
B)CN IV controls adduction of the eye
C)CN III controls abduction of the eye
D)If the right eye is not able to depress in an adducted position,it indicates CN IV dysfunction.

Question 10

Which of the following is appropriate in testing for CN II visual field screening?

A)Snellen chart testing
B)Testing the ability to see objects in the peripheral vision
C)Test visual field in both eyes simultaneously
D)Testing for excessive intraocular pressure
