A nurse is caring for a client who has bulimia nervosa.
Which of the following findings should the nurse expect?

Choice A rationale

Schizophrenia is a chronic, progressive neuropsychiatric disorder that often requires increasing levels of support as symptoms evolve and impact functional capacity. As the disease advances through adulthood, individuals may experience more severe positive and negative symptoms, cognitive deficits, and social isolation, necessitating greater reliance on mental health services, financial aid, and community resources to manage their condition and maintain a reasonable quality of life. This escalating need reflects the long-term, debilitating nature of the illness.

Choice B rationale

The typical onset of schizophrenia is during late adolescence or early adulthood, generally between the ages of 16 and 30 years. Diagnosis after 40 years of age is considerably less common, although late-onset schizophrenia can occur. Early recognition and intervention are crucial for better prognosis and management of the disorder. This age range is associated with significant neurodevelopmental changes, which are implicated in the etiology of schizophrenia.

Choice C rationale

The life expectancy for individuals with schizophrenia is significantly reduced compared to the general population, primarily due to higher rates of co-occurring medical conditions, such as cardiovascular disease and diabetes, often exacerbated by lifestyle factors, medication side effects, and limited access to healthcare. While the exact reduction varies, a common estimate is a reduction of 10 to 20 years, making 50.2 years a plausible but potentially low average, highlighting the serious health disparities faced by this population.

Choice D rationale

Co-occurring mental health illnesses, or comorbidity, are frequently diagnosed in individuals with schizophrenia. Substance use disorders, depression, anxiety disorders, and obsessive-compulsive disorder are common co-occurring conditions. These comorbidities often complicate the clinical presentation, treatment, and prognosis of schizophrenia, requiring integrated and comprehensive care approaches to address the multifaceted needs of the client.

Choice A rationale

Depersonalization involves feelings of detachment from one's own body or mental processes, while derealization involves feelings of unreality or detachment from one's surroundings. While these can be dissociative symptoms, they specifically relate to altered perceptions of self or reality, not primarily to the inability to recall specific traumatic events, which is characteristic of amnesia.

Choice B rationale

Factitious disorder, also known as Munchausen syndrome, is a mental disorder in which a person fakes or induces symptoms of illness to gain attention or sympathy. This condition involves intentional deception and feigned symptoms, which is fundamentally different from an involuntary inability to recall traumatic memories, which is a genuine cognitive impairment.

Choice C rationale

Dissociative amnesia is characterized by an inability to recall important personal information, usually of a traumatic or stressful nature, that is too extensive to be explained by ordinary forgetfulness. This memory disturbance is a psychological defense mechanism, often occurring after severe psychological trauma such as sexual assault, where the mind blocks out distressing memories.

Choice D rationale

Dissociative identity disorder, previously known as multiple personality disorder, involves the presence of two or more distinct personality states that recurrently take control of the individual's behavior, accompanied by an inability to recall personal information. While it involves amnesia, it is more complex than isolated memory loss and includes distinct identity states.
