Correct Answer is C
Explanation
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
The priority intervention for a client in DKA is to initiate a continuous IV insulin infusion to lower the blood glucose level and reverse the ketosis. Insulin also helps to correct the electrolyte imbalance and acid-base imbalance in DKA.
