Staging choices for infants include which combination?

• A. Active REM sleep and quiet sleep
• B. Indeterminate sleep, wake and quiet sleep
• C. Active REM sleep and delta sleep
• D. Indeterminate sleep, active REM sleep and quiet sleep

Answer: (D)

Infant sleep staging uses three distinct states: Active Sleep, Quiet Sleep, and Indeterminate Sleep. Active Sleep is REM-like, with eye movements and irregular breathing; Quiet Sleep is non-REM-like, with more regular breathing and less movement; Indeterminate Sleep is when the EEG/behaviors can’t be clearly classified as AS or QS. Delta sleep isn’t treated as a separate infant stage, and a separate wake state isn’t considered a sleep stage in this context. So the combination that includes all three infant-defined states—Indeterminate Sleep, Active Sleep, and Quiet Sleep—is the correct one.
