Which of the following is a characteristic of bulimia nervosa?

Correct Answer: B

Rationale: The correct answer is B. Bulimia nervosa is characterized by recurrent episodes of binge eating followed by compensatory behaviors such as self-induced vomiting, excessive exercise, or fasting. This behavior helps individuals to control their weight and manage guilt associated with binge eating. Choice A is incorrect as bulimia is not associated with severe caloric restriction and weight loss. Choice C is more characteristic of anorexia nervosa, not bulimia. Choice D describes anorexia nervosa, where individuals refuse to eat and engage in self-imposed starvation.

Correct Answer: C

Rationale: The correct answer is C: guarded and distant. This is because individuals with paranoid personality disorder typically exhibit suspiciousness, mistrust, and a reluctance to confide in others. They tend to be hypervigilant and wary of others, leading them to appear guarded and distant. A: Superficially charming is incorrect because individuals with paranoid personality disorder are more likely to be cautious and suspicious rather than charming. B: Intense and impulsive is incorrect as this description is more characteristic of individuals with borderline personality disorder, not paranoid personality disorder. D: Friendly and open is incorrect because individuals with paranoid personality disorder are more likely to be reserved and cautious in their interactions. In summary, the correct answer is C because individuals with paranoid personality disorder typically exhibit guarded and distant behavior due to their suspicious and mistrustful nature.

Correct Answer: D

Rationale: The correct answer is D because it involves a behavior that is potentially harmful and puts others at risk. Setting limits is essential to prevent violence and protect both the patient and others. A: Clinging behavior is not inherently harmful. B: Flirtatious behavior, while inappropriate, does not pose a direct threat. C: Hypervigilance and refusal to attend activities may indicate underlying issues but do not require immediate limit setting for safety.

Correct Answer: A

Rationale: The correct answer is A because fear of gaining weight and loss of control over eating are core features of anorexia nervosa. Patients with anorexia often have an intense fear of gaining weight, leading to restrictive eating behaviors. This fear is accompanied by a sense of loss of control over their eating habits. Choice B is incorrect because lack of concern about food intake and weight is not a common emotional response in anorexia nervosa. Choice C is incorrect as excessive joy and pride in achieving weight loss are more characteristic of other eating disorders like bulimia nervosa or orthorexia. Choice D is incorrect because denial of the need for treatment and weight restoration may be present in some cases but is not a common emotional response in anorexia nervosa.

Correct Answer: B

Rationale: The correct answer is B: Extreme weight loss due to excessive food restriction. Patients with anorexia nervosa typically exhibit severe food restriction leading to significant weight loss. This behavior is driven by a distorted body image and fear of gaining weight. Binge eating followed by purging (choice A) is characteristic of bulimia nervosa, not anorexia nervosa. Frequent overeating with a lack of control (choice C) is a feature of binge eating disorder, not anorexia nervosa. Excessive weight gain through overeating and exercise (choice D) does not align with the weight loss seen in anorexia nervosa.
