A hospitalized client is told that he has terminal cancer. The client adamantly believes that the physician is wrong despite biopsy results and MRI findings. This is an example of which of the following?

D. 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.

A. 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. Anorexia nervosa is driven by deep-seated fears, anxieties, and perceptions related to body image and weight.

B. 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.

C. 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.

B. This is the correct priority action. Serotonin syndrome can be life-threatening if not promptly recognized and treated. The physician needs to be notified immediately so that appropriate actions can be taken to manage the client's symptoms and potentially adjust the medication regimen.

A. Aspirin is not appropriate for treating serotonin syndrome. Monitoring the client's symptoms is important, but this action does not address the potential seriousness of the symptoms described.

C. Delaying notification could lead to worsening of symptoms and potential complications. Given the potential seriousness of serotonin syndrome, waiting until it's convenient is not appropriate.

D. While headache, palpitations, and stiffness could potentially be side effects of antidepressant medication, the combination of these symptoms raises concern for serotonin syndrome, which requires immediate medical attention rather than reassurance alone.
