Correct Answer: D

Rationale: Dissociative fugue involves sudden, unexpected travel away from home or one's customary place of activities, accompanied by an inability to recall one's past. It is usually associated with amnesia for personal information and is not characterized by depersonalization symptoms. DID involves the presence of two or more distinct personality states or identities within an individual, which alternate and take control of behavior. Each identity may have its own unique way of perceiving and interacting with the environment, which differs from the symptoms described in the scenario. Dissociative amnesia involves the inability to recall important personal information, usually related to stressful or traumatic events. While depersonalization symptoms can occur in dissociative amnesia, the hallmark feature is memory loss rather than the feeling of detachment from one's body. Depersonalization disorder is a dissociative disorder where individuals feel detached from themselves, as if they are observing their own thoughts, feelings, sensations, or actions from outside their body. This can lead to a sense of unreality or detachment from the environment or one's own experiences. It is often triggered by stressful events or trauma, and it can occur in individuals experiencing grief or loss, such as the surviving husband in this scenario.

Correct Answer: A,B

Rationale: A. Denial is a common initial reaction where individuals refuse to accept the reality of their illness. They may minimize symptoms, avoid medical advice, or believe that the diagnosis is incorrect. Denial can serve as a defense mechanism to protect individuals from the shock and emotional distress of a diagnosis. B. Anger is another stage where individuals may experience frustration, resentment, or hostility towards themselves, others, or the situation. They might feel angry about their diagnosis, the impact it has on their life, or towards healthcare providers and caregivers. C. Grief is a natural response to loss and can be experienced when individuals face the changes, limitations, or potential outcomes associated with their illness. Grief involves feelings of sadness, despair, and mourning for the life they had before the illness, as well as for potential losses in the future. However, it is not a typical stage of the illness experience. D. Dependency refers to a stage where individuals may rely on others for physical, emotional, or practical support due to the challenges posed by their illness. This stage can involve seeking assistance with daily activities, relying on healthcare providers for treatment, or leaning on family and friends for emotional support. However, it is not a typical stage of the illness experience.

Correct Answer: D

Rationale: While adolescents with anorexia may exhibit behaviors related to food restriction, excessive exercise, or other rituals, the core issue goes beyond simply adhering to appropriate behavior. Control is a central issue in anorexia nervosa. Adolescents often use strict control over food intake and exercise as a way to manage overwhelming feelings of anxiety, fear, and uncertainty. By controlling their food intake and weight, individuals with anorexia may seek to regain a sense of mastery and control over their lives amidst other stressors. Anxiety is a common comorbidity in individuals with anorexia nervosa, but it is not the primary issue. Anxiety often stems from fears related to weight gain, body image dissatisfaction, and the perceived loss of control. Anxiety exacerbates the obsessive thoughts and behaviors around food and weight seen in anorexia nervosa. Body image disturbance is a fundamental issue in anorexia nervosa. Adolescents with anorexia often have a distorted perception of their body size and shape, seeing themselves as overweight even when significantly underweight. This distorted body image drives their obsessive behaviors around food restriction and excessive exercise in an attempt to achieve an unrealistic and unhealthy body image.

Correct Answer: A,C,D,F

Rationale: 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.

Correct Answer: D

Rationale: 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. 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. 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. 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.
