Answer to Question 1

Ans:
B

Feedback:

A sudden change in the osmolality of extracellular fluid can also occur when blood glucose levels are lowered too rapidly, and this can cause cerebral edema, more common in children than in adults. Answers A, B, and C all have some component of signs and symptoms of DKA rather than cerebral edema signs and symptoms (answer B).

Answer to Question 2

Ans:
D

Feedback:

This woman's hepatitis is probably caused by an autoimmune disorder rather than a virus. Lamivudine, peginterferon/ribavirin, and interferon alfa-2b are all antiviral agents. Autoimmune hepatitis is a chronic, usually progressive, inflammatory disease of the liver. Corticosteroids are the mainstay of treatment and have been shown to produce remission. Azathioprine, an immunosuppressant medication, is sometimes used along with prednisone. Using both medications may allow you to take a smaller dose of prednisone, reducing its side effects. Most people with this disease require long-term maintenance treatment.
