The nurse is performing a neurologic assessment on a patient. Which action should the nurse take to adequately test the effectiveness for the hypoglossal nerve?

A. The hypoglossal nerve (cranial nerve XII) controls tongue movements, so asking the patient to move the tongue side to side tests its function. B. Checking air movement through each nostril assesses the olfactory nerve (cranial nerve I). C. Asking the patient to shrug the shoulders tests the accessory nerve (cranial nerve XI). D. Asking the patient to wrinkle the forehead tests the facial nerve (cranial nerve VII).
