Correct Answer: B

Rationale: The correct answer is B: Primary sleep disorders. These disorders directly affect the sleep-wake cycle or timing mechanisms of the body. Sleep apnea (A) is a specific disorder characterized by pauses in breathing during sleep, not a general category. Tertiary sleep disorders (C) are not a recognized classification; the primary and secondary are the main categories. "None of the above" (D) is incorrect as primary sleep disorders are indeed related to abnormal functioning of the sleep-wake cycle.

Correct Answer: B

Rationale: The correct answer is B: Provide a structured environment with clear expectations around eating behaviors. This is important in managing bulimia nervosa as it helps establish a routine, promotes healthy eating habits, and prevents binge-purge cycles. It provides consistency and boundaries, reducing the likelihood of impulsive behaviors.

This does not align with the impulsive and self-destructive behaviors described in the scenario. B: Histrionic personality disorder is characterized by attention-seeking behaviors and excessive emotions. While there may be some overlap with impulsive behaviors, it does not fully capture the severity and self-destructiveness of the client's actions.

This goal focuses on establishing regular eating habits and promoting a healthy relationship with food, which are crucial in the treatment of anorexia nervosa. Choices A and D are incorrect as rapid weight gain and resuming normal physical activities may not be safe or sustainable goals for someone with anorexia nervosa. Choice B is also incorrect because body image satisfaction is a complex issue that may not be directly addressed solely through treatment for anorexia nervosa.
