The death rate from anorexia is higher than any other mental illness. Death usually results from which of the following? (Select all that apply.)

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.

A. Lithium is excreted primarily by the kidneys, and its clearance can be affected by changes in fluid balance. It's important for clients taking lithium to maintain a stable and adequate fluid intake to help regulate lithium levels in the body. Stable fluid intake helps maintain electrolyte balance, which is crucial for the proper function of lithium and prevention of adverse effects.

B. Lithium can affect sodium reabsorption in the kidneys. High levels of sodium intake can alter lithium levels in the body, potentially leading to toxicity. Therefore, clients on lithium therapy are often advised to maintain a consistent and moderate level of sodium intake. Excessive dietary salt can interfere with lithium's therapeutic effects.

C. Restricting fluid intake is not recommended unless there are specific medical reasons to do so. Lithium therapy generally requires adequate hydration to maintain kidney function and prevent dehydration, which can affect lithium levels.

D. Exercising in hot weather can lead to increased sweating and fluid loss, which can potentially affect lithium levels by altering hydration status. However, the primary concern during exercise in hot weather is maintaining adequate hydration rather than restricting it.
