ATI N103N103 Fundamentals Final Exam | Nurselytic

Correct Answer: A

Rationale: The correct answer is A: Ask the client to clench their teeth and assess facial sensation. This method assesses both the motor function (clenching teeth) and sensory function (facial sensation) of cranial nerve V, also known as the trigeminal nerve. By asking the client to clench their teeth, the nurse can evaluate the strength and symmetry of the muscles innervated by this nerve. Assessing facial sensation involves testing the client's ability to feel touch or pain on different areas of the face supplied by the trigeminal nerve. This comprehensive assessment covers both motor and sensory functions of cranial nerve V.


Choices B, C, and D are incorrect as they do not specifically target the trigeminal nerve. Asking the client to identify scented aromas (
B) tests olfactory nerve function, reading a Snellen chart (
C) assesses optic nerve function, and asking the client to raise his eyebrows (
D) evaluates facial nerve function.
