A disorder that interrupts normal sleep patterns and is characterized by repeated, brief jerks of the arms and legs that occur every 20 to 60 seconds during the beginning of sleep is called:

Correct Answer: D

Rationale: The correct answer is D: None of the above. The disorder described in the question is Periodic Limb Movement Disorder (PLMD), not any of the options provided. PLMD involves involuntary movements during sleep, which are different from the symptoms of insomnia, narcolepsy, or hypersomnia. Insomnia is difficulty falling or staying asleep, narcolepsy is a neurological disorder characterized by excessive daytime sleepiness, and hypersomnia is excessive daytime sleepiness despite getting enough sleep. Therefore, the correct answer is D as none of the provided options accurately describe the specific disorder mentioned in the question.

Correct Answer: C

Rationale: The correct answer is C, dental enamel erosion and swollen parotid glands, in patients with bulimia nervosa. This is due to frequent self-induced vomiting. Enamel erosion is caused by stomach acid exposure during vomiting. Swollen parotid glands result from repeated purging. Choices A, B, and D are incorrect because low blood pressure and bradycardia are more common in anorexia nervosa, hyperactivity and increased energy are not typical in bulimia nervosa, and constipation and abdominal bloating are not specific to this disorder.

Correct Answer: B

Rationale: The correct answer is B because abuse of diuretics and laxatives is a common behavior in individuals with bulimia nervosa to control weight. This behavior is known as purging. Choice A is incorrect as personality traits vary among individuals with bulimia nervosa. Choice C is incorrect as disinterest in sexual activity is not a typical feature of this disorder. Choice D is incorrect as individuals with bulimia nervosa often experience episodes of binge eating, indicating they do experience hunger at times.

Correct Answer: C

Rationale: The correct answer is C: Explore alternate ways to handle frustrating topics in the group. This approach focuses on addressing the underlying issue of the client's aggressive behavior by finding healthier ways to manage emotions and conflicts. It promotes therapeutic communication and helps the client develop coping strategies. Secluding the client (choice A) may escalate the situation and reinforce negative behavior. Putting the client in restraints (choice B) is a physical intervention that should only be used as a last resort for safety reasons. Telling the client to leave the group (choice D) may not address the root cause of the behavior and could lead to further isolation and resentment. Ultimately, exploring alternate ways to handle frustrating topics is the most therapeutic and effective approach in this scenario.

Correct Answer: C

Rationale: The correct answer is C because addressing the psychological and emotional factors is crucial in treating anorexia nervosa. This disorder is not solely about weight or food intake; it often involves deeper psychological issues such as body image distortion, low self-esteem, and control issues. By focusing on the underlying psychological and emotional factors, therapists can help patients understand and cope with these issues, leading to more effective and sustainable recovery. Choices A, B, and D are incorrect because they overlook the complexity of anorexia nervosa and may even exacerbate the patient's condition by neglecting the root causes of the disorder.
