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)?
Disequilibrium with movement
Deviation of the tongue from midline
Loss of peripheral vision
mobility to smell
The Correct Answer is A
Choice A reason:
Disequilibrium with movement is correct. The vestibulocochlear nerve (cranial nerve VIII) is responsible for both hearing (cochlear component) and balance (vestibular component). Impaired function of this nerve can result in problems with equilibrium and balance, leading to symptoms such as disequilibrium or vertigo (a sensation of spinning or whirling), especially with movement.
Choice B Reason:
Deviation of the tongue from midline is incorrect. This is related to cranial nerve XII (hypoglossal nerve) and its role in tongue movement and control.
Choice C Reason:
Loss of peripheral vision is incorrect. This is related to cranial nerve II (optic nerve) and its role in vision.
Choice D Reason:
Inability to smell is incorrect. This is related to cranial nerve I (olfactory nerve) and its role in the sense of smell.

Correct Answer is B
Explanation
Choice A Reason:
Administer a sedative medication is incorrect. Administering a sedative can help the client feel more comfortable during the procedure, but ensuring allergy safety comes first.
Choice B Reason:
Determine whether the client has an allergy to local anaesthetics is correct. The priority intervention for the nurse is to determine whether the client has an allergy to local anaesthetics. Local anaesthetics are typically used to numb the area before a thoracentesis, and ensuring the safety of the client is essential. An allergy to local anaesthetics can result in serious adverse reactions, so it's crucial to identify any allergies before proceeding with the procedure.
Choice C Reason:
Describe the sensations the client will feel during the procedure is incorrect. Providing information about the sensations is important for client education and comfort, but verifying allergies is more critical.
Choice D Reason:
Reinforce the importance of lying still during the procedure - Encouraging the client to lie still is important for the procedure's success and client safety, but confirming allergies takes priority.
Correct Answer is C
Explanation
Choice A Reason:
Diplopia is incorrect. Diplopia is double vision and is not a specific sign of malnutrition.
Choice B Reason:
Hyperproteinemia is incorrect - Malnutrition often leads to hypoalbuminemia (low levels of albumin, a protein), not hyperproteinemia.
Choice C Reason:
Cachexia is correct. Cachexia refers to a state of severe malnutrition and muscle wasting that can occur in individuals with chronic illnesses, especially advanced cancer, heart failure, or certain inflammatory conditions. It is characterized by significant weight loss, muscle atrophy, weakness, and fatigue. Cachexia goes beyond simple malnutrition and is a more severe manifestation of nutritional deficiency.
Choice D Reason:
Hypermagnesemia is incorrect - Malnutrition is more likely to cause deficiencies in minerals like magnesium, not excess levels (hypermagnesemia).
