The nurse stands behind the client and whispers "5-B-6." This technique is used to assess which of the following Cranial Nerves?

A. The whispered voice test is used to assess the function of Cranial Nerve VIII, which is responsible for hearing and balance. The nurse's whisper tests the auditory function of this nerve. B. The vagus nerve is involved in swallowing, voice production, and parasympathetic functions but is not assessed by whispering. C. This nerve controls lateral eye movement, and a whispered voice test does not assess eye movement. D. This nerve also controls eye movement, specifically the superior oblique muscle, and is not evaluated by the whispered voice test.
