Impaired environmental interpretation syndrome related to metabolic disorders is a condition that affects how the body processes nutrients and energy.

Correct Answer: A

Rationale: The correct answer is A because the term "environmental interpretation" refers to how the body processes external stimuli, which can be affected by metabolic disorders. Choice B is incorrect as cognitive disorders do not directly impact environmental interpretation. Choice C is incorrect as sensory disorders specifically affect sensory processing, not environmental interpretation. Choice D is incorrect as option A accurately reflects the relationship between impaired environmental interpretation and metabolic disorders.

Correct Answer: B

Rationale: The correct answer is B because an obsession with calorie intake and extreme weight loss is a hallmark symptom of anorexia nervosa. Individuals with anorexia nervosa typically have a distorted body image and an intense fear of gaining weight. This leads them to restrict their food intake severely, leading to extreme weight loss. Choice A is incorrect because excessive eating followed by purging is more characteristic of bulimia nervosa, not anorexia nervosa. Choice C is incorrect as compulsive exercising is more commonly associated with another eating disorder called orthorexia nervosa. Choice D is incorrect as binge eating episodes with a lack of control are symptoms of binge eating disorder, not anorexia nervosa.

Correct Answer: B

Rationale: The correct answer is B: Assess and monitor the patient's electrolyte levels. This is the priority intervention because purging in bulimia nervosa can lead to electrolyte imbalances, which can be life-threatening. Monitoring electrolyte levels is crucial to prevent complications such as cardiac arrhythmias or organ damage. A: Ensuring access to therapy and counseling is important but not the priority in this case where immediate medical attention is needed for potential electrolyte imbalances. C: Encouraging a balanced diet is essential in the long term but not the immediate priority when dealing with the potential medical complications of purging. D: Providing education about dangers is important, but it is not the most critical intervention at this moment compared to monitoring electrolyte levels.

Correct Answer: C

Rationale: The correct answer is C. Patients with anorexia nervosa often have bradycardia and hypotension due to the physiological effects of severe malnutrition. Explanation: Severe restriction of food intake leads to decreased energy stores, causing the body to slow down its metabolic processes, including heart rate and blood pressure. Bradycardia and hypotension are common findings in individuals with anorexia nervosa. Summary: A: Increased appetite and food cravings are not expected findings in anorexia nervosa as patients typically have a decreased appetite. B: A body mass index (BMI) in the normal range is not expected in anorexia nervosa, as patients often have a low BMI due to significant weight loss. D: Elevated blood pressure and rapid pulse are not typical findings in anorexia nervosa; rather, patients may present with low blood pressure and bradycardia.

Correct Answer: A

Rationale: The correct answer is A: Establishing a contract for safety with the client. This is the priority intervention as it focuses on ensuring the client's immediate safety. By setting up a contract for safety, the nurse can collaborate with the client on identifying warning signs and developing a plan to prevent self-harm. Choice B (Teaching the client ways to manage anger) and Choice C (Helping the client tolerate feelings) are important interventions but may not be as urgent as ensuring the client's safety in this scenario. Choice D (Implementing behavioral modification) is not the priority because the client's safety needs to be addressed first before focusing on behavioral changes.
