Which of the following is true about facial assessment for cranial nerve VII?

• A. Focus on auditory function
• B. Check for abnormal movements or asymmetry
• C. Test strength of arm movements
• D. Assess the ability to swallow

Answer: (B)

The focus of cranial nerve VII, also known as the facial nerve, is primarily concerned with facial expressions and muscle movements related to the face. Therefore, checking for abnormal movements or asymmetry is crucial when assessing this nerve. Asymmetrical facial movements can indicate potential neurological issues or damage to the facial nerve, which may manifest in conditions such as Bell's palsy or other neurological disorders. By observing the patient's ability to perform expressions such as smiling, frowning, or closing the eyes tightly, healthcare providers can ascertain the integrity of cranial nerve VII. This assessment gives important clinical information about the nerve's function and can help identify underlying pathologies. In contrast, the focus of auditory function relates to cranial nerve VIII (the vestibulocochlear nerve), while testing arm movements pertains to motor function of the upper extremities typically associated with other cranial nerves or the brachial plexus. Assessing swallowing is relevant to cranial nerves IX and X, which are involved in the gag reflex and swallowing mechanisms. Thus, the correct focus for cranial nerve VII assessment revolves around facial symmetry and movement.
