What is the main issue for adolescents with anorexia?

D. Bipolar disorder is characterized by episodes of mania or hypomania (elevated, expansive, or irritable mood, increased energy, racing thoughts) alternating with episodes of depression (sadness, loss of interest, low energy). The mood swings can be severe, and the transition between mood states can occur suddenly.

A. Major depressive disorder is characterized by persistent feelings of sadness and loss of interest or pleasure in activities. It does not involve manic or hypomanic episodes, which are essential for diagnosing bipolar disorder.

B. Dysthymic disorder involves chronic, low-grade depression that lasts for at least two years. It does not typically present with episodes of mania or hypomania.

C. Personality disorders involve enduring patterns of behavior, cognition, and inner experience that deviate markedly from the expectations of the individual's culture. While some personality disorders can present with mood instability, the description of severe and sudden mood swings from mania to depression is not characteristic of personality disorders in general.

B. This is the most appropriate initial action. One-to-one observation ensures constant monitoring of the client's safety and prevents further harm, such as another suicide attempt or self-harm. Given the client's history of depression and recent suicide attempt, ensuring their safety is paramount.

A. This option is not the first priority because while addressing anorexia nervosa is important, safety concerns related to the suicide attempt and potential substance abuse take precedence. Making a weight gain contract requires the client's cooperation and readiness, which may not be feasible immediately upon admission.

C. While assessing the severity of depression is crucial, it is secondary to ensuring immediate safety in this context. The client's safety must be established first through continuous observation and intervention.

D. While important to understand the substances involved in the suicide attempt, this action is secondary to ensuring ongoing safety through direct observation. Toxicology results can guide subsequent treatment decisions but are not as urgent as immediate safety measures.
