Answer to Question 1

ANS: D
The diathesis-stress model integrates the effects of biology and environment on the development of mental illness. Certain genes or genetic combinations produce a predisposition to a disorder. When an environmental stressor challenges an individual with a predisposition to a disorder, the expression of a mental disorder may result. The community health model is the primary method of care for people with serious and persistent mental illness. This model includes team care, case management, outreach, and a variety of rehabilitative and recovery approaches to help prevent exacerbations of illness. The systems theory uses a holistic view, which emphasizes the relation-ship between the elements of a unit and the whole. An understanding of the whole occurs through the examination of interactions and relationships that exist between the parts.

Answer to Question 2

ANS: C
Biochemical changes of the brain are being studied as causes of mental illness. Angiography is used to screen for abnormalities of the vascular system, such as atherosclerosis and brain tumors, that can lead to behavior changes. Antipsychotic drugs are only appropriate for treatment of cer-tain mental illnesses. More is known about the functions of the brain than any time in history; however, treatment of mental illness continues to be challenging.
