Neurology Quiz

A patient presents with loss of corneal reflex. Which cranial nerves are most likely affected?

• CN II and CN III

• CN V and CN VII

• CN III and CN IV

• CN IX and CN X

In Weber's test, sound is lateralized to the affected ear. This finding is most consistent with:

• Normal hearing

• Sensorineural hearing loss

• Conductive hearing loss

• Mixed hearing loss

Which lobe of the cerebrum is primarily responsible for understanding language (Wernicke's area)?

• Frontal

• Temporal

• Parietal

• Occipital

During Rinne's test, a patient hears bone conduction longer than air conduction. What type of hearing loss does this suggest?

• Sensorineural

• Conductive

• Central auditory

• Mixed

Which reflex reappearing in an adult is a sign of frontal lobe lesion?

• Patellar reflex

• Snout reflex

• Achilles reflex

• Biceps reflex

A lesion in the right cerebellar hemisphere typically results in:

• Left-sided tremors

• Right-sided coordination deficits

• Bilateral spasticity

• Contralateral visual field defects

Loss of stereognosis indicates damage to:

• Cerebellum

• Primary motor cortex

• Sensory cortex (parietal lobe)

• Brainstem

Which cranial nerve is assessed by asking the patient to shrug shoulders against resistance?

• CN IX

• CN XI

• CN XII

• CN VIII

A positive Romberg's test with eyes closed indicates dysfunction in:

• Cerebellum

• Vestibular or proprioceptive pathways

• Motor cortex

• Frontal lobe

Which cranial nerve damage is suspected if a patient cannot close their eye tightly and shows facial asymmetry?

• CN V

• CN VII

• CN III

• CN IX
