2024 PN NCLEX Questions Nursing Practice Question
The gag reflex test assesses which cranial nerves?
Correct Answer: A
Rationale: The gag reflex test primarily evaluates cranial nerves IX (Glossopharyngeal) and X (Vagus). Nerve IX is responsible for the sensory component, detecting stimuli in the throat, while nerve X controls the motor response, facilitating the gag reflex.
Option B (V and VII) involves the trigeminal and facial nerves, which are not directly related to the gag reflex.
Option C (IX and XII) includes cranial nerve XII (Hypoglossal), which is involved in tongue movement, not the gag reflex.
Option D (V and X) involves the trigeminal nerve, which does not play a role in the gag reflex.
