Answer to Question 1
ANS: C
African-Americans are about twice as likely to have AD as whites. The higher incidence of hypertension and diabetes in these populations may increase the risk of AD. There is no current research to support a relationship between the other options and the development of AD.
Answer to Question 2
ANS: D
Depression is the most common psychiatric disorder in older adults. Bipolar disorders tend to level out in later life, and individuals tend to have longer periods of depression. Relapses in older adults are usually precipitated by medical problems. Older adults tend to be rapid cyclers, cycling from mania to deep depression in a much shorter period of time than they did when they were younger. Depression was a frequent misdiagnosis and those with bipolar disorder were prescribed antidepressant medications, which inadvertently placed them at risk for manic episodes and increased risk of rapid cycling.
