Appropriate teaching for a patient with bulimia nervosa who binges and purges is:

Correct Answer: A

Rationale: Step-by-step rationale: 1. A: Not skipping meals or restricting food promotes regular eating patterns, helps stabilize blood sugar levels, and reduces the urge to binge. 2. B: Eating a small meal after purging could reinforce the binge-purge cycle and is not a healthy approach. 3. C: Eating a large breakfast but skipping lunch can lead to imbalanced eating habits and is not recommended for treating bulimia nervosa. 4. D: None of the above options provide a comprehensive and effective approach to managing bulimia nervosa symptoms.

Correct Answer: C

Rationale: The correct answer is C because anorexia nervosa is characterized by restricting food intake and having an intense fear of gaining weight. This behavior leads to severe weight loss and malnutrition. Choice A is typically associated with bulimia nervosa, where binge eating is followed by purging. Choice B also aligns with bulimia, as self-induced vomiting is a common purging behavior. Choice D describes behaviors more typical of binge eating disorder, where individuals consume large quantities of food followed by excessive exercise. In anorexia nervosa, the primary focus is on severe food restriction and the fear of weight gain, leading to significantly low body weight.

Correct Answer: A

Rationale: The correct answer is A: Provide a structured mealtime environment with supervision. This is the most important initial intervention for a patient with bulimia nervosa because it addresses the immediate health concern of disordered eating behavior. By providing a structured mealtime environment with supervision, the patient can establish regular eating patterns, learn healthier eating habits, and reduce the risk of purging behaviors. This intervention also helps in restoring proper nutrition and addressing any underlying issues related to food and eating. Choice B is incorrect because support groups may be beneficial but are not the most critical initial intervention. Choice C is incorrect as antianxiety medications do not directly address the disordered eating behavior. Choice D is also incorrect as assessing family dynamics and home environment is important but not as crucial as addressing the immediate eating disorder symptoms.

Correct Answer: D

Rationale: The correct answer is D: Are initially often charming. This is because individuals with antisocial personality disorder often exhibit charm and charisma to manipulate others for personal gain. This behavior is known as "charm offensive" and can be used to deceive and exploit others. This initial charm can make it difficult for others to recognize their true motives and manipulative nature. Incorrect options: A: Demand constant attention - Individuals with antisocial personality disorder may appear self-centered and manipulative but not necessarily demand constant attention. B: Tolerate frustration well - Clients with antisocial personality disorder often have difficulty managing frustration and may resort to aggressive or impulsive behavior. C: Have well-developed superegos - Individuals with antisocial personality disorder typically lack empathy and have a weak or underdeveloped superego, leading to a disregard for social norms and the rights of others.

Correct Answer: B

Rationale: The correct answer is B: Provide a calm, structured environment with consistent mealtimes. This is the priority intervention because individuals with bulimia nervosa benefit from a stable and supportive environment to establish regular eating patterns and reduce anxiety around mealtimes. This intervention helps promote a sense of safety and predictability, which are crucial for managing the eating disorder. Encouraging regular exercise (Choice A) may exacerbate compulsive behaviors related to bulimia. Weight loss (Choice C) should not be the focus as it can worsen the patient's condition. Offering a high-protein diet (Choice D) may not address the underlying psychological issues associated with bulimia.
