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
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. Avoid using an electric razor
This is not directly relevant to trigeminal neuralgia management. Although it may be important for clients to avoid stimulating the face in general, an electric razor is not a specific concern for trigeminal neuralgia.
B. Meats should be served hot
Hot foods should actually be avoided, as extreme temperatures can trigger trigeminal neuralgia pain. Therefore, this recommendation is incorrect.
C. Teeth should be brushed prior to each meal
This is a reasonable recommendation for maintaining oral hygiene, but it does not specifically address managing trigeminal neuralgia pain. It is not as effective as the correct measure for managing trigeminal neuralgia.
D. Chew food on the unaffected side
Clients with trigeminal neuralgia may experience severe pain on one side of the face, especially when chewing. To reduce pain, it is recommended to chew food on the unaffected side to avoid triggering pain.
Correct Answer is C
Explanation
A. 63% TBSA
This value is too high based on the Rule of Nines calculation.
B. 45% TBSA
This overestimates the burn area.
C. 36% TBSA
Using the Rule of Nines, the TBSA is calculated as follows:
- Entire right arm (anterior + posterior): 9%
- Posterior trunk: 18%
- Posterior right leg: 9%
- Total TBSA = 9% + 18% + 9% = 36%
D. 27% TBSA
This underestimates the affected areas.
