The nurse is performing a neurological assessment on a client and is assessing the function of cranial nerves III, IV, and VI. Assessment of which aspect of function will yield the best information about these cranial nerves?

A. Response to verbal stimuli does not directly assess the function of cranial nerves III, IV, and VI. B. Affect, feelings, or emotions are related to the assessment of other neurological functions and do not evaluate the ocular cranial nerves specifically. C. Eye movements are the primary function of cranial nerves III (oculomotor), IV (trochlear), and VI (abducens), which control eye movement and provide essential information about their function. D. Insight, judgment, and planning relate more to cognitive function and do not directly assess the function of the cranial nerves in question.
