The nurse is testing the function of cranial nerve XI (Spinal accessory nerve). Which finding would the nurse expect if the nerve is intact?

Follows an object with eyes without nystagmus or strabismus

Moves the tongue out midline without tremors or deviation

Moves the head and shoulders against resistance with equal strength

Demonstrates full range of the neck

Answer and Explanation

The Correct Answer is C

A. Follows an object with eyes without nystagmus or strabismus
Cranial nerves III (oculomotor), IV (trochlear), and VI (abducens) control eye movement. CN XI does not control eye movement.

B. Moves the tongue out midline without tremors or deviation
Cranial nerve XII (hypoglossal nerve) controls tongue movement.

C. Moves the head and shoulders against resistance with equal strength
Cranial nerve XI (spinal accessory nerve) controls the sternocleidomastoid and trapezius muscles. If intact, the client can shrug shoulders and turn the head against resistance with equal strength.

D. Demonstrates full range of the neck
Full range of motion in the neck involves multiple muscles, not just those innervated by CN XI.

Correct Answer is D

Explanation

A. Continue to monitor the client as a paralytic ileus is possible

Paralytic ileus can occur postoperatively, but sudden severe pain and distension indicate a more serious issue, such as bowel infarction.

B. Administer the PRN stool softener to the client

A stool softener is inappropriate if the client has a possible bowel obstruction or ischemia.

C. Obtain an order to insert a nasogastric tube set to low suction

An NG tube may help relieve distension, but it does not treat the underlying cause. The priority is to notify the surgeon.

D. Report the assessment findings to the surgeon

Absent bowel sounds, severe pain, and distension suggest bowel ischemia, a life-threatening complication requiring immediate surgical intervention.

A. inability to understand directions B. Lesion of cranial nerve IX C. Dysfunction of the cerebellum D. Vestibular disease

Correct Answer is C

Explanation

A. Inability to understand directions
The client's issue is with motor coordination, not comprehension.

B. Lesion of cranial nerve IX
Cranial nerve IX (Glossopharyngeal) is associated with swallowing and taste, not motor coordination.

C. Dysfunction of the cerebellum
The cerebellum controls coordination and fine motor movements. The client's inability to perform rapid alternating movements (dysdiadochokinesia) suggests cerebellar dysfunction.

D. Vestibular disease
Vestibular disorders cause dizziness, vertigo, and balance problems but do not typically affect rapid alternating movements.
