Which of the following is a symptom of damage to Cranial Nerve VIII?

Cranial Nerve VIII, also known as the vestibulocochlear nerve, is primarily responsible for hearing and balance. Damage to this nerve can lead to symptoms related to its functions. Vertigo refers to a sensation of spinning or dizziness, which occurs due to vestibular dysfunction, and tinnitus is the perception of noise or ringing in the ears, linked to cochlear issues. Therefore, the presence of vertigo and tinnitus indicates impairment in the functions of Cranial Nerve VIII.

The other choices involve symptoms associated with other cranial nerves. Dry mouth is typically due to dysfunction of the salivary glands, often associated with Cranial Nerve VII (the facial nerve). A deviated tongue can indicate issues with Cranial Nerve XII (the hypoglossal nerve), which controls tongue movement. Weakness in shrugging the shoulder is related to Cranial Nerve XI (the accessory nerve), which supplies the sternocleidomastoid and trapezius muscles. Each of these symptoms points to a specific cranial nerve, making vertigo and tinnitus the correct choice associated with damage to Cranial Nerve VIII.
