The PMHNP is evaluating a new client who reports symptoms of one hypomanic episode and at least one major depressive episode. Which psychiatric condition is most closely associated with these experiences?

Choice A reason: Bipolar I disorder requires at least one manic episode, not just hypomania, making this inconsistent with the presentation. Choice B reason: Bipolar II disorder is characterized by at least one hypomanic episode and at least one major depressive episode without a history of full mania, matching the client’s symptoms. Choice C reason: Cyclothymic disorder involves chronic, milder mood fluctuations but does not meet criteria for full hypomanic or major depressive episodes. Choice D reason: Schizoaffective disorder includes mood episodes along with psychotic symptoms, which are not reported in this client’s history.
