It is a secondary dementia indicated by loss of recent memory and disorientation to time and place.

Correct Answer: A

Rationale: The correct answer is A: Alzheimer's disease. Alzheimer's disease is a common type of dementia characterized by progressive cognitive decline, including loss of recent memory and disorientation to time and place. This is due to the accumulation of amyloid plaques and neurofibrillary tangles in the brain. Vascular dementia (B) is caused by reduced blood flow to the brain, leading to cognitive impairment. Lewy body dementia (C) is characterized by the presence of abnormal protein deposits called Lewy bodies in the brain. Choosing D (None of the above) would be incorrect as Alzheimer's disease specifically matches the description provided in the question.

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 interacting with clients who have similar problems in a therapy group for eating disorders helps prevent secondary gains related to feeling different or unique in their struggles. This interaction can offer a sense of validation, support, and understanding, which can be crucial for individuals with eating disorders. It fosters a sense of belonging and reduces the feelings of isolation that often accompany these disorders. Choice A is incorrect because the primary focus of group therapy for eating disorders is to address and work through issues related to food and body image, rather than distracting clients from these concerns. Choice C is incorrect because the purpose of group therapy is to provide a safe space for clients to explore and address their personal concerns within a supportive group setting, not to avoid dealing with them. Choice D is also incorrect as interacting with similar others in a therapy group has specific benefits for individuals with eating 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.
