Answer to Question 1

ANS: C
Some patients with bipolar disorder, especially those who have only short periods between episodes, have a favorable response to the anticonvulsants carbamazepine and valproate. Phenytoin is also an anticonvulsant but is not used for mood stabilization. Carbamazepine seems to work better in patients with rapid cycling and in severely paranoid, angry patients with manic episodes.

Answer to Question 2

ANS: A
At this time, the interplay of complex independent variables is most likely the best explanation of the cause for bipolar disorder. Various theories implicate genetics, endocrine imbalance, early stress, and neurotransmitter imbalances.
