Answer to Question 1

D
The two most consistent neurobiological research findings in schizophrenia are imaging studies that show reduced brain volume and abnormal function, and neurochemical studies that show alterations of neurotransmitter systems affecting the prefrontal cortex and the limbic system.

Answer to Question 2

B
Psychobiology and technology experienced dramatic growth in the 1980s and 1990s including advanced understanding of brain function, understanding the relationships of the brain, behavior, emotion, cognition, neurotransmitters and neuronal receptors, as well as improved brain imaging. The options related to home care and outpatient care settings are not true. The option related to the psychodynamic model of therapy is also incorrect because advances in the psychodynamic model of psychiatric care were made by psychiatrists and psychologists, not by psychiatric nurses.
