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)?
Inability to smell
Loss of peripheral vision
Disequilibrium with movement
Deviation of the tongue from midline
The Correct Answer is C
C. The vestibulocochlear nerve is responsible for both the vestibular function and the cochlear function. Impaired function of the vestibulocochlear nerve could result in symptoms related to vestibular dysfunction, such as disequilibrium (feeling unsteady or off balance) especially with movement.
A. The olfactory nerve (cranial nerve I) is responsible for the sense of smell.
B. Loss of peripheral vision is typically associated with impairment of the optic nerve (cranial nerve II), which is responsible for vision.

D. Extreme temperatures, both hot and cold, can trigger sickle cell crises in individuals with sickle cell disease. Cold temperatures can cause vasoconstriction and increase the risk of sickling of red blood cells, while hot temperatures can lead to dehydration. Therefore, clients with sickle cell disease should avoid exposure to extreme temperatures and take precautions to maintain a comfortable environment, especially during hot summer months and cold winter seasons.
A. Clients with sickle cell disease are at increased risk of developing complications from influenza (flu) infections. Therefore, it is highly recommended that clients with sickle cell disease receive an annual flu vaccination to reduce their risk of contracting the flu and its associated complications.
B. Hydration is crucial for individuals with sickle cell disease as it helps prevent dehydration and reduces the risk of sickling of red blood cells, which can trigger a sickle cell crisis.
C. Alcohol can exacerbate dehydration and increase the risk of vaso-occlusive crises in individuals with sickle cell disease.
