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?
The child maintains balance when standing with eyes closed.
The child has symmetrical jaw strength when biting down.
The child exhibits a gag reflex when stimulated with a tongue blade.
The child correctly identifies specific scents.
The Correct Answer is B
The trigeminal nerve is responsible for sensation in the face and motor functions such as biting and chewing.
Symmetrical jaw strength when biting down indicates proper functioning of the trigeminal nerve.
Choice A is wrong because it assesses the vestibulocochlear nerve, not the trigeminal nerve.
Choice C is wrong because it assesses the glossopharyngeal and vagus nerves, not the trigeminal nerve.
Choice D is wrong because it assesses the olfactory nerve, not the trigeminal nerve.

Choice D is wrong because constipation is not a symptom of intussusception.
Correct Answer is A
Explanation

Choice B is wrong because Creatinine 0.3 mg/dL is not an answer because it falls within the normal range for creatinine levels.
Choice C is wrong because BUN 12 mg/dL is not an answer because it falls within the normal range for BUN levels.
