Knowing that she is referring to neurotransmitters, which of the following would be the best response by the nurse?
A) "Recent studies have found that neurotransmitters do not play a role in bipolar disorders."
B) "Clients with bipolar disorder often have high levels of GABA in manic states."
C) "Levels of dopamine and serotonin have a significant effect on mania and depression."
D) "Low levels of the neurotransmitter acetylcholine are associated with mania."

Feedback:
One hypothesis of bipolar disorder is that dysregulation in dopamine and serotonin systems combines with deficits in other systems (eg, GABA) to produce symptoms of mood disorders. Clients with bipolar disorder may have low plasma levels of GABA during depressive and manic phases.
