CDN Eating Disorder Treatment 2 — Questions and Answers
Question 1: Which medical complication is most associated with chronic laxative abuse in bulimia nervosa?
- Hyperkalemia
- Hypokalemia (Correct answer)
- Hypernatremia
- Hypercalcemia
Correct answer: Hypokalemia
Chronic laxative abuse causes significant potassium loss through the GI tract, leading to hypokalemia.
Question 2: A patient with ARFID avoids foods based on sensory characteristics. Which treatment approach is most evidence-based?
- Cognitive behavioral therapy with exposure and response prevention (Correct answer)
- Motivational interviewing alone
- Dialectical behavior therapy
- Psychodynamic therapy
Correct answer: Cognitive behavioral therapy with exposure and response prevention
CBT with exposure and response prevention helps patients gradually tolerate feared sensory properties of foods.
Question 3: During refeeding of a severely malnourished anorexia patient, which electrolyte requires closest monitoring during the first 72 hours?
- Sodium
- Calcium
- Phosphorus (Correct answer)
- Magnesium
Correct answer: Phosphorus
Hypophosphatemia is the hallmark of refeeding syndrome and the electrolyte requiring most urgent monitoring.
Question 4: In treating binge eating disorder (BED), which pharmacological agent is FDA-approved and works by reducing binge frequency?
- Olanzapine
- Lisdexamfetamine (Correct answer)
- Topiramate
- Sertraline
Correct answer: Lisdexamfetamine
Lisdexamfetamine (Vyvanse) is the only FDA-approved medication specifically indicated for moderate-to-severe BED.
Question 5: A dietitian is using the 'Health at Every Size' (HAES) framework for a patient with an eating disorder. This approach prioritizes:
- Achieving a BMI within the normal range
- Intuitive eating and well-being over weight outcomes (Correct answer)
- Strict caloric counting to normalize intake
- Rapid weight restoration as the primary goal
Correct answer: Intuitive eating and well-being over weight outcomes
HAES prioritizes health-promoting behaviors, intuitive eating, and psychological well-being independent of weight or BMI outcomes.
Question 6: Which behavioral therapy component specifically targets the cycle of restricting → binging → purging in bulimia nervosa?
- Mindfulness-based stress reduction
- Regular eating and elimination of dietary restriction (Correct answer)
- Schema therapy
- Interpersonal psychotherapy
Correct answer: Regular eating and elimination of dietary restriction
Establishing a pattern of regular, structured eating breaks the restrict-binge-purge cycle that characterizes bulimia nervosa.
Question 7: A teenager with anorexia nervosa is being treated using Family-Based Treatment (FBT). In Phase 1, who controls the patient's food intake?
- The patient with therapist guidance
- The dietitian via a meal plan
- The parents (Correct answer)
- A multidisciplinary team jointly
Correct answer: The parents
In FBT Phase 1 (weight restoration), parents take full control of food choices and eating to externalize the illness from the patient.
