Q

To test the sensory portion of this cranial nerve: with the patient’s eyes closed, a piece of cotton and safety pin are used to alternately touch each side of the patient’s face. The pt is asked to classify each contact as sharp or dull. A positive result is the absence of sensation or inability to differentiate between sharp and dull.

Q

Your patient’s visual acuity is being tested the a Rosenbaum chart. First the left eye is tested, then the right eye. He is tested with his glasses on so this represents corrected visual acuity. He has 20/70 vision in the left eye and 20/40 vision in the right. His decreased visual acuity is from damage to this CN:

Q

How do you assess the motor portion of CNs IX and X?

A

CN XI - spinal accessory

35
Q

While assessing extra-occular eye movements, you note that your patient’s eye is slightly adducted when the patient looks straight ahead. The eye abducts sluggishly, and even when abduction is maximal, the lateral sclera is exposed. You suspect the patient is experiencing:

A

CN 6 palsy

A

CN VII - Facial

58
Q

A

CN VIII - Acoustic - the vestibulolcochlear nerve

60

A

Oculomotor - motor: pupillary constriction, opening the eye (lid elevation), and most extraocular movements

61
Q

Which CN innervates the muscles involved in shoulder shrugging and in turning the head?

A

spinal accessory - CN XI innervates the sternocleidomastoid and the trapezius muscles

62
Q
A
63
Q

During CN assessment, your patient contract the left sternocleidomastoid muscle easily, but the right muscle contraction is absent. Looking at the back of the patient, the left trapezius muscle is outline and present but the right is atrophic and hard to identify. These findings indicate a lesions of :

A

The right CN XI

64
Q

Your patient has weakness of the lower half of the left side of his face including the orbicularis oculi muscle but sparing the forehead. This is consistent the an upper motor neuron lesion or lesion of what CN?

A

CN VII

65
Q

Binocular diplopia occures in neuropathy of what CNs?

A

CN III, IV, and VI

66
Q

Loss of smell occurs in sinus conditions, head trauma, smoking, aging, use of cocaine, and Parkinson disease. This is found when assessing of which CN?

A

CN I - Olfactory

67
Q

Difficulty clenching the jaw or moving it to the opposie side suggest masseter and lateral pterygoid weakness, respectively, jaw deviation during opening points to weakness on the deviating side. Look for unilateral weakness of this CN (pontine lesions)- Bilateral weakness points to bilateral hemispheric disease - Absent blinking on both sides occurs with lesions of this CN

A

CN V - trigeminal

68
Q

The following abnormal finding suggest issues with these two CNs: hoarseness, nasal voice, or difficulty swallowing.

A

CN IX and X - glossopharyngeal and vagus

69
Q

When assessing this CN - you may find tongue atrophy and fasciculations due to amyotrophic lateral sclerosis and past polio or protruded tongue that eviates away from the side of the cortical lesions.

A

CN XII
