A man, aged 84 years, was stopped for going through a red light in a small town where he lives. He told the officer, 'It wasn't there yesterday.' He was unable to tell the officer his address and demonstrated labile mood, seeming pleasant one minute and angry the next. The officer took the man home to discuss his condition with the family and found that he has been wandering around the neighborhood, sometimes taking tools from people's garages, saying they belong to him. The family reluctantly agreed that he should go to the emergency department. What cardinal sign of Alzheimer's disease does this patient demonstrate?

Correct Answer: A

Rationale: The correct answer is A: Agnosia. Agnosia is the inability to recognize or interpret sensory information, such as objects, people, sounds, or shapes. In this case, the patient's inability to recognize the red light, his own address, and the ownership of tools indicates a problem with perception and recognition. This aligns with the symptoms of agnosia commonly seen in Alzheimer's disease. Choices B and C are incorrect. Apraxia is the inability to perform purposeful movements, and aphasia is the loss of ability to understand or express speech. These symptoms are not the primary cardinal sign demonstrated by the patient in the scenario. Choice D, "None of the above," is also incorrect as the patient's symptoms align with the characteristics of agnosia.

Correct Answer: D

Rationale: The correct answer is D because the main focus of medical management for anorexia is not to encourage rapid weight gain, as it can lead to serious health complications. Encouraging the client to eat voluntarily is also not the main focus, as anorexia involves psychological factors that go beyond simple lack of appetite. Teaching more appropriate food choices is not the main focus either, as anorexia requires comprehensive treatment that addresses underlying emotional issues. Overall, the main focus is on a multidisciplinary approach that includes therapy, nutritional counseling, and medical monitoring to address the physical and psychological aspects of the disorder.

Correct Answer: D

Rationale: The correct answer is D because allowing the teen to skip meals if she feels full can reinforce unhealthy eating behaviors associated with anorexia nervosa. This statement contradicts the essential goal of promoting regular and adequate meal intake to support recovery. Encouraging the teen to eat when not hungry may be necessary to restore normal eating patterns. Choices A, B, and C align with supporting the teen's nutritional needs and recovery process.

Correct Answer: A

Rationale: The correct answer is A. In Anorexia Nervosa treatment, the primary goal is weight restoration to a healthy level. This is crucial for physical health and recovery. Stabilizing weight at a normal level is a key indicator of treatment success. Choices B, C, and D are incorrect as they do not address the core issue of weight restoration, which is essential in treating Anorexia Nervosa. Group therapy, body image satisfaction, and cognitive function are important aspects of treatment but not the primary outcome measure for patients with anorexia nervosa.

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
