A nurse caring for a patient with altered level of consciousness is preparing to test cranial nerve VII. The nurse would complete which of the following assessment techniques to elicit a response from cranial nerve VII?
A) Palpate the trapezius muscle while the patient shrugs his shoulders against resistance
B) Administer the whisper or watch tick test
C) Observe for symmetry of facial movements, such as a smile
D) Note any hoarseness in the patient's voice
Ans: C
Feedback: Cranial nerve VII is the facial nerve. An appropriate assessment technique would include observing for symmetry while the patient performs facial movements such as smiling, whistling, elevating eyebrows, and frowning. Palpating and noting the strength of the trapezius muscle while the patient shrugs shoulders against resistance assesses cranial nerve XI (spinal accessory). Assessing cranial nerve VIII (acoustic) utilizes the whisper or watch-tick test to evaluate hearing. Noting any hoarseness in the patient's voice involves assessment of cranial nerve X (vagus). Refer to Chart 60-1.
