A client with a personality disorder asks the nurse, 'Is it true I have an inherited brain disorder?' The nurse replies, knowing that:

Correct Answer: D

Rationale: Rationale: D is correct because individuals with personality disorders can manifest biological markers indicating a potential biological basis for the disorder. This does not imply that all individuals with personality disorders display brain abnormalities (B), have errors in brain glucose metabolism (C), or that there is definitive proof of inheritance (A). Biological markers suggest a potential biological component but do not guarantee inheritance or specific brain abnormalities.

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.

Correct Answer: B

Rationale: The correct answer is B because monitoring vital signs and electrolyte levels closely is crucial in managing a patient with bulimia nervosa who has a history of purging. Purging can lead to electrolyte imbalances and dehydration, which can have serious consequences such as cardiac arrhythmias and electrolyte disturbances. By closely monitoring vital signs and electrolyte levels, nurses can quickly identify and intervene in case of any abnormalities, preventing potential life-threatening complications. Choice A is incorrect because emotional support and stress management are important but not the priority when dealing with physical complications from purging. Choice C is incorrect because encouraging exercise may exacerbate the patient's unhealthy behaviors and should be approached cautiously. Choice D is incorrect because identifying triggers is important but not as immediate as monitoring vital signs and electrolyte levels in this situation.
