Final answer:
Leigh Anne is receiving an integrated treatment for anorexia nervosa, involving nutritional intervention with a nasogastric tube and behavioral treatment with positive reinforcement for eating, aiming to normalize eating habits and achieve a healthy weight.
Step-by-step explanation:
The treatment that Leigh Anne is undergoing encompasses multiple aspects of care specific to anorexia nervosa. The insertion of a nasogastric tube at night provides essential nutrition, which is a therapeutic intervention often necessary for individuals severely underweight and malnourished due to their eating disorder. The positive reinforcement Leigh Anne receives when she consumes any part of her meals is part of behavioral treatment, encouraging healthy eating behaviors. While meals remain small to not overwhelm the patient, additional snacks support gradual weight restoration and nutritional stabilization - both critical in recovery from anorexia nervosa.
An important goal of this integrated treatment plan is to establish normalized eating habits and help Leigh Anne achieve a healthy weight range. The comprehensive approach to recovery also commonly involves mental health counseling, which addresses the psychological aspects of eating disorders, such as distorted body image and unhealthy attitudes towards food and weight.
