A nurse is reinforcing teaching with a group of parents about adolescent suicide. Which of the following findings poses the highest risk of suicide completion in adolescents?

A. Parental substance use disorder is incorrect. While living in a home with substance abuse can contribute to emotional distress, it is not the highest risk factor for suicide completion. B. Bipolar disorder is correct. Mental health disorders, particularly mood disorders such as bipolar disorder, significantly increase the risk of suicide. Adolescents with bipolar disorder are at a high risk due to impulsivity, depressive episodes, and potential feelings of hopelessness. C. Loss of family income is incorrect. Financial instability can contribute to stress and emotional distress, but it is not as directly correlated with suicide risk as a diagnosed mental health disorder. D. Parental divorce is incorrect. Although parental divorce can cause emotional distress and increase vulnerability to depression, it is not the strongest predictor of suicide compared to bipolar disorder.
