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. Deviation of the tongue occurs in injury to the hypoglossal nerve.

Correct Answer is D
Explanation
D. A thrill is a palpable vibration or buzzing sensation felt over the graft site, caused by turbulent blood flow. In the context of an arteriovenous graft, a palpable thrill is typically considered a positive finding, indicating adequate circulation through the graft. It suggests that blood is flowing smoothly from the arterial to the venous side of the graft.
A. The presence of a bruit is typically considered a positive finding, indicating adequate blood flow through the graft. Therefore, the absence of a bruit may indicate inadequate circulation or a potential complication such as graft occlusion or stenosis.
B. Normal blood pressure is not a specific indicator of the adequacy of circulation through an arteriovenous graft.
C. A dilated appearance of the graft may suggest venous hypertension or increased pressure within the graft. While this could indicate adequate blood flow, it may also suggest problems such as venous stenosis or thrombosis, which can impede circulation through the graft.
Correct Answer is D
Explanation
D. Diet plays a crucial role in managing ulcerative colitis symptoms. Certain foods may trigger flare-ups, while others may be better tolerated. A dietitian can provide personalized dietary advice to help manage symptoms, ensure adequate nutrition, and optimize overall health.
A. Ulcerative colitis is a chronic inflammatory bowel disease that primarily affects the colon and rectum. While pain management is crucial, it is not a priority at this point.
B. Hospice services are generally provided to individuals who have a terminal illness and are nearing the end of life. While ulcerative colitis can be a serious condition, it is not typically considered a terminal illness in itself.
C. A wound, ostomy, and continence nurse (WOCN) specializes in the care of patients with ostomies (such as those resulting from surgery for ulcerative colitis), wounds, and continence issues. The client does not require the services at this point as the decision for the surgery has not been made.
