A female client with anorexia nervosa and a cardiac condition was prescribed an antidepressant before she regained weight during her treatment course. The nurse should be aware of the possibility of which condition in this client?

A. Severely restricted food intake can lead to imbalances in electrolytes such as potassium, sodium, and chloride. These imbalances can disrupt normal heart rhythm (arrhythmias) and other vital functions, potentially leading to cardiac arrest, which is a common cause of death in individuals with anorexia nervosa.

B. Individuals with anorexia nervosa are at increased risk of suicidal thoughts and behaviors. This risk may be due to the severe psychological distress associated with the disorder, as well as the physical complications that can feel overwhelming. Suicide can unfortunately be a tragic consequence in some cases.

D Dehydration is a significant risk in individuals with anorexia nervosa, especially when combined with electrolyte imbalances. Dehydration can lead to organ failure, particularly kidney failure, which can be life-threatening if not promptly treated.

E. Severe muscle wasting can occur in individuals with anorexia nervosa, particularly in later stages of the disorder. Loss of muscle mass contributes to overall physical weakness and compromises essential bodily functions, potentially leading to organ failure and death.

C. Anorexia nervosa itself does not directly cause diabetes. However, individuals with severe anorexia may develop metabolic disturbances, including insulin resistance, due to malnutrition. This can lead to abnormal blood sugar levels, but diabetes as a direct cause of death in anorexia is less common compared to other complications.

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.
