A patient who is diagnosed with a cervical herniated disc complains of pain. The nurse concludes that the patient's pain is caused by which of the following?

A) Motor component of IV (Trochlear): The trochlear nerve primarily controls the superior oblique muscle of the eye, which is responsible for downward and lateral eye movements. The findings described do not relate to eye movement and therefore do not indicate dysfunction of this nerve.

B) Motor and sensory components of XI (Accessory): The accessory nerve innervates the sternocleidomastoid and trapezius muscles, primarily affecting head rotation and shoulder elevation. The symptoms noted in the assessment do not pertain to these muscle functions, so this option is not correct.

C) Motor component of VII (Facial): The signs of asymmetry in frowning, uneven eyebrow lifting, sagging eyelids, and air escaping when puffing the cheeks are characteristic of dysfunction in the facial nerve (cranial nerve VII). This nerve controls the muscles of facial expression, and impairment would lead to the described asymmetrical movements.

D) Motor component of X (Vagus) and sensory component of XII (Hypoglossal): The vagus nerve affects autonomic functions and some swallowing muscles, while the hypoglossal nerve controls tongue movements. Neither nerve is primarily responsible for the facial expressions described in the assessment findings, making this option incorrect.

A) Avoid hand and foot massages: This statement may not be accurate. Gentle massages can sometimes help with circulation and comfort for individuals with peripheral neuropathy. However, caution should be exercised to avoid injury, as the sensation may be diminished.
B) Use a mirror to inspect feet daily: This is an essential teaching point. Clients with peripheral neuropathy often have decreased sensation in their feet, making it difficult to notice injuries or sores. Using a mirror allows them to check for any signs of injury or changes that could lead to complications, such as infections or ulcers.
C) Increase medication for pain as necessary: While managing pain is important, the client should be advised to consult with their healthcare provider before making any changes to their medication regimen. Self-adjusting medication could lead to unintended side effects or complications.
D) Set the water heater at 120°F: This is not advisable for someone with peripheral neuropathy, as they may not have normal temperature sensation. A lower setting is recommended to prevent burns, as the individual may not feel when the water is too hot.
