Answer to Question 1

D
Based on a few research studies, current thinking suggests that deficits in serotonin might play a role in bulimia nervosa. There is no research to support the correctness of any of the other options.

Answer to Question 2

B
Patients with cognitive deficits might be overwhelmed by stimuli and might misperceive something on television as occurring in reality. If this occurs, stimuli should be reduced to simplify the environment. The other measures would be somewhat less effective, because they do not include removing the offending stimulus (the television).
