2024 PN NCLEX Questions Nursing Practice Question
While assisting with data collection regarding the neurological system, the nurse asks the client to puff out both cheeks. Which cranial nerve is the nurse assessing?
Correct Answer: B
Rationale: Puffing out both cheeks primarily assesses the facial nerve (Cranial Nerve VII), which controls the muscles of facial expression, including those used for blowing. This action tests the motor function of the facial nerve, confirming its integrity.
Option A, Vagus (Cranial Nerve X), is involved in autonomic functions, not facial movement. Option C, Abducens (Cranial Nerve VI), controls lateral eye movement, unrelated to cheek puffing. Option D, Oculomotor (Cranial Nerve III), primarily manages eye movements and pupil constriction, making it irrelevant for this assessment.
