Which instruction should the nurse give a client who is prescribed lithium carbonate (lithium)?

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. Conversion disorder involves the presence of neurological symptoms that are inconsistent with known neurological or medical conditions. These symptoms often manifest as sensory or motor deficits, such as blindness, paralysis, or seizures, without a clear organic basis. The symptoms are not intentionally produced and are not explained by another medical or psychiatric condition.

A. Hypochondriasis, now known as illness anxiety disorder, involves excessive worry or preoccupation with having a serious illness despite medical reassurance and lack of significant physical symptoms. It does not typically involve sensory or neurological symptoms such as blindness.

C. Malingering involves the intentional production or exaggeration of symptoms for secondary gain, such as financial compensation, avoiding military duty, or obtaining drugs. In malingering, there is typically a clear external incentive for the behavior, which is not evident in the soldier's case.

D. Somatization disorder (now termed somatic symptom disorder) involves multiple and recurrent physical symptoms that are distressing and lead to excessive thoughts, feelings, and behaviors related to these symptoms. It does not typically present with sudden onset of sensory deficits like blindness.
