People with insomnia have difficulty with which of the following?
A) only with falling asleep
B) only with returning to sleep after waking in the night
C) only with waking up too early
D) with falling asleep, returning to sleep after waking, and waking up too early
Answer: D
Rationale: Although insomnia is often thought of as a single disorder, it may be more appropriate to refer to insomnias in the plural. Onset insomnia occurs when a person has difficulty falling asleep (30 minutes or more), maintenance insomnia occurs when an individual cannot easily return to sleep after waking in the night, and terminal insomnia is a situation in which a person wakes up too early—sometimes hours too early—and cannot return to sleep.
