A nurse is performing a cranial nerve assessment on a school-age child. Which of the following findings indicates proper functioning of the child's trigeminal nerve?

A. The child exhibits a gag reflex when stimulated with a tongue blade. The gag reflex is associated with cranial nerves IX (glossopharyngeal) and X (vagus), not the trigeminal nerve. B. The child maintains balance when standing with eyes closed. Balance is assessed in part by cranial nerve VIII (vestibulocochlear nerve) and also involves the cerebellum, not the trigeminal nerve. C. The child correctly identifies specific scents. Identifying specific scents is related to cranial nerve I (olfactory nerve), not the trigeminal nerve. D. The child has symmetrical jaw strength when biting down. The trigeminal nerve (cranial nerve V) controls the muscles of mastication. Symmetrical jaw strength when biting down indicates proper functioning of this nerve.
