Which nursing diagnosis is most appropriate for a patient with bulimia nervosa who engages in frequent purging behaviors?

Correct Answer: B

Rationale: The correct answer is B: Risk for injury related to electrolyte imbalances. Patients with bulimia nervosa who engage in frequent purging behaviors are at risk for electrolyte imbalances due to loss of potassium, sodium, and other essential minerals. This can lead to serious complications such as cardiac arrhythmias and organ damage. Monitoring and addressing electrolyte imbalances is crucial in the care of these patients to prevent potential harm. A: Ineffective coping related to inability to control impulses is not the most appropriate diagnosis as it does not directly address the immediate risk of electrolyte imbalances in this scenario. C: Imbalanced nutrition: less than body requirements related to food refusal is not the most appropriate diagnosis as the primary concern in bulimia nervosa with purging behaviors is the risk of electrolyte imbalances, not necessarily inadequate food intake. D: Disturbed body image related to fear of weight gain is not the most appropriate diagnosis as it does not address the immediate physical health risks

Correct Answer: B

Rationale: The correct answer is B. Monitoring the patient's weight and nutritional intake closely is the priority intervention for a patient with anorexia nervosa as it directly addresses the immediate health risks associated with the disorder, such as malnutrition and weight loss. By closely monitoring these parameters, healthcare providers can assess the patient's progress and make necessary adjustments to prevent further complications. Choice A is incorrect because while addressing body image concerns is important in the long term, it is not the priority intervention when the patient's physical health is at risk. Choice C is incorrect as providing education on healthy eating and exercise may not be effective if the patient is not yet in a stable physical condition to absorb and apply the information. Choice D is incorrect as offering emotional support is valuable, but it is not the priority intervention in this case where the patient's physical health needs immediate attention.

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: 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: 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.
