A nurse is performing a cranial nerve assessment on a client following a head injury. Which of the following findings should the nurse expect if the client has impaired function of the vestibulocochlear nerve (cranial nerve VIII)?
Deviation of the tongue from midline
Loss of peripheral vision
Disequilibrium with movement
Inability to smell
The Correct Answer is C
The nurse should expect disequilibrium with movement if the client has impaired function of the vestibulocochlear nerve, as this nerve is responsible for hearing and balance. Deviation of the tongue from midline indicates impairment of the hypoglossal nerve (cranial nerve XII), loss of peripheral vision indicates impairment of the optic nerve (cranial nerve II), and inability to smell indicates impairment of the olfactory nerve (cranial nerve I).

Correct Answer is B
Explanation
A 2-g sodium diet means limiting sodium intake to no more than 2000 mg per day. Sodium is found in salt and many processed foods, such as canned vegetables, soups, sauces, and baked goods. Sodium can cause fluid retention and worsen heart failure symptoms, such as shortness of breath, swelling, and fatigue. Therefore, the client should avoid adding salt or salt substitutes (such as baking soda) to their foods and choose fresh or frozen vegetables over canned ones. Lemon juice is a low-sodium alternative that can add flavor to foods without increasing sodium intake.
Correct Answer is B
Explanation
To assess a client for a positive Chvostek’s sign, the nurse should tap gently on the cheek, specifically two centimeters in front of the ear, over the facial nerve (also known as CN VII). This test is used to check for hypocalcemia, a condition that can lead to tetany, which is the involuntary contraction of muscles. A twitch of the facial muscles in response to this tapping indicates a positive Chvostek’s sign. This is particularly relevant following a thyroidectomy, as the procedure can indirectly affect the parathyroid glands, potentially leading to hypocalcemia
