Answer to Question 1
A
Changes in schedule that affect circadian rhythms, such as work shifts that alter usual sleep patterns, can result in fatigue that is not related to mental health status. Other factors that alter sleep include changes in light and darkness and temperature changes. Vacations in the same time zone should not affect sleep, whereas food and fluid intake should enhance sleep by reducing risk of nocturia or indigestion.
Answer to Question 2
B

These three symptoms need only to have lasted 4 days. In contrast to mania, hypomanic symptoms need not cause any disturbances in functioning but must be observable by others.
