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

A. Anxiety is characterized by feelings of worry, fear, and apprehension about future events or uncertain outcomes. In this situation, the client's concerns about her husband's chronic illness diagnosis, his treatment, and financial implications (due to his inability to work) indicate that she is experiencing anxiety. These worries are typical responses to stressful life events and uncertainties.

B. Shock is a sudden and intense emotional reaction typically experienced immediately after a traumatic or unexpected event. While the client may initially experience shock upon hearing her husband's diagnosis, ongoing worry about treatment and financial concerns suggests a more prolonged state of anxiety rather than acute shock.

C. Withdrawal refers to a disengagement or retreat from social interactions or activities. There is no indication in the scenario that the client is withdrawing from social interactions. Rather, she is actively expressing concerns and seeking support, which is inconsistent with withdrawal.

D. Anger involves feelings of hostility, frustration, or resentment towards others or situations. While anger could potentially arise in response to the stressors described, the primary emotion expressed by the client in this scenario is worry and concern, which aligns more closely with anxiety than anger.

A. Purging is a behavior associated with bulimia nervosa, where individuals engage in self-induced vomiting, misuse of laxatives, diuretics, or enemas to compensate for binge eating episodes.

C. Night eating disorder is characterized by recurrent episodes of night eating, typically waking up from sleep to consume food, often accompanied by a lack of appetite in the morning and a significant portion of daily caloric intake occurring after the evening meal.

D. Pica is a disorder characterized by persistent eating of non-nutritive substances, such as clay, dirt, chalk, or paper. Pica involves eating non-food substances and is recognized as an eating disorder due to the potential harm it can cause.

F. Binge eating disorder involves recurrent episodes of consuming large amounts of food within a discrete period, accompanied by a sense of loss of control over eating behavior. Unlike bulimia nervosa, individuals with binge eating disorder do not engage in purging behaviors.

B. Cataplexy is a symptom of narcolepsy, characterized by sudden episodes of muscle weakness or loss of muscle tone, often triggered by strong emotions.

E. Nocturnal myoclonus, also known as periodic limb movement disorder, involves involuntary muscle contractions or jerks during sleep, which can disrupt sleep but is not related to eating behaviors.
