A nurse is performing a neurologic assessment on the client and notes a positive Romberg test. This test for balance is related to which of the following cranial nerves?
VII.
VI.
VIII.
IX.
The Correct Answer is C
Choice A rationale
Cranial nerve VII (Facial nerve) controls muscles of facial expression and functions in taste sensations from the anterior two-thirds of the tongue, not balance.
Choice B rationale
Cranial nerve VI (Abducens nerve) controls lateral eye movement and has no role in balance or proprioception.
Choice C rationale
Cranial nerve VIII (Vestibulocochlear nerve) is responsible for hearing and balance. A positive Romberg test indicates issues with proprioception or vestibular function, which is directly linked to this nerve.
Choice D rationale
Cranial nerve IX (Glossopharyngeal nerve) involves taste sensation from the posterior third of the tongue and some swallowing functions, not balance.

Correct Answer is C
Explanation
Choice A rationale
Ativan (lorazepam) is used for immediate control of seizures but is not used for long-term maintenance.
Choice B rationale
Cerebyx (fosphenytoin) is used for seizure control but is generally not used for long-term maintenance.
Choice C rationale
Phenobarbital is a barbiturate that is commonly used for long-term maintenance to prevent seizures. It works by depressing the central nervous system and reducing the spread of seizure activity.
Choice D rationale
Valium (diazepam) is used for acute seizure control but not for long-term seizure prevention.
Correct Answer is ["A","B","E"]
Explanation
Choice A rationale
Pinpoint pupils can indicate opioid use or damage to the pons, a part of the brainstem. This finding warrants further evaluation to determine the underlying cause and appropriate intervention.
Choice B rationale
Absence of pupillary response suggests severe brain injury or brainstem dysfunction. It is a critical finding that requires immediate medical attention to address potential life-threatening conditions.
Choice C rationale
Pupil reaction to light is a normal response indicating intact cranial nerve function. This finding does not raise neurologic concerns and does not require further investigation.
Choice D rationale
Quick pupil reaction is a normal response and indicates healthy cranial nerve function. This finding is not associated with neurologic concerns.
Choice E rationale
Unequal pupils, or anisocoria, can indicate increased intracranial pressure, brain injury, or nerve damage. This finding requires prompt assessment and intervention to prevent further complications.
