The APRN asks the patient to elevate his eyebrows, close his eyes, smile, frown, and puff out his cheeks. Which cranial nerve is the NP assessing by issuing these instructions?
Cranial nerve VII (CN VII), facial nerve
Cranial nerve V (CN V), trigeminal nerve
Cranial nerve III (CN III), oculomotor nerve
Cranial nerve VI (CN VI), abducens nerve
The Correct Answer is A
Choice A reason: This choice is correct because the facial nerve (CN VII) controls the muscles of facial expression, including eyebrow elevation, eye closure, smiling, frowning, and cheek puffing. Assessing these movements evaluates CN VII function.
Choice B reason: The trigeminal nerve (CN V) primarily mediates facial sensation and mastication muscles, not facial expressions.
Choice C reason: The oculomotor nerve (CN III) controls most extraocular eye movements and eyelid elevation, not the full range of facial expressions tested.
Choice D reason: The abducens nerve (CN VI) controls lateral eye movement only and is not involved in facial expressions.

Correct Answer is B
Explanation
Choice A reason: Hydrocodone is an opioid and is generally not first-line for chronic neuropathic pain, due to dependency risks and limited efficacy for burning neuropathic pain.
Choice B reason: This choice is correct because gabapentin is a first-line treatment for diabetic neuropathic pain. It targets nerve hyperexcitability and reduces burning, tingling, and neuropathic discomfort.
Choice C reason: Acetaminophen is useful for nociceptive pain but is not effective for neuropathic pain caused by diabetic peripheral neuropathy.
Choice D reason: Botulinum toxin is used for muscle spasticity or localized pain syndromes, not generalized diabetic neuropathy.
Correct Answer is C
Explanation
Choice A reason: Fright syndromes typically involve transient anxiety and sadness but do not include the physical manifestations associated with Khayal.
Choice B reason: Weakness of the nervous system, such as neurasthenia, is associated with chronic fatigue and somatic complaints but does not reflect the acute episodic presentation of Khayal.
Choice C reason: Khayal is a Cambodian culture-bound syndrome characterized by a wind attack or sudden anxiety episode with physical symptoms, including tinnitus, palpitations, and neck soreness. It resembles a panic attack culturally contextualized.
Choice D reason: Excessive rumination or “thinking too much” is associated with some African or Caribbean syndromes but does not describe Khayal.
