2024 PN NCLEX Questions Nursing Practice Question
When testing the function of the oculomotor, trochlear, and abducens nerves, which parameter does a nurse check to determine their function?
Correct Answer: B
Rationale: To assess the function of the oculomotor, trochlear, and abducens nerves, eye movements are evaluated. These cranial nerves are responsible for controlling most eye movements, including tracking and coordinating gaze.
Option A, tongue symmetry, pertains to the hypoglossal nerve, not the ocular nerves. Option C, facial symmetry, relates to the facial nerve, which controls facial expressions. Option D, the corneal reflex, involves the trigeminal and facial nerves and is not a direct measure of the eye movement functions of the oculomotor, trochlear, and abducens nerves. Thus, eye movements are the key parameter for assessing these specific cranial nerves.
