Answer to Question 1

Ans: D
Feedback:
Eating disorders can be best understood in terms of a multifactorial etiology. Most experts agree that anorexia and bulimia develop from a complex interaction of individual, family, and sociocultural factors. Research strongly suggests that eating disorders may originate in part from hypothalamic, hormonal, neurotransmitter, or biochemical disturbances. Whether the biologic abnormalities seen in clients with eating disorders contribute to the disorders or are secondary to the dysregulation in the eating behavior remains unclear.

Answer to Question 2

Ans: A
Feedback:
Anorexia is characterized by a voluntary refusal to eat and typically a weight less than 85 of what is considered normal for height and age. Clients with anorexia have a distorted body image and, to the bewilderment of others, view their emaciated bodies as fat.
