Which of the following is characteristic of active sleep in a neonate?

• A. regular respirations
• B. absence of eye movements
• C. frequent movements
• D. trace alternant

Answer: (C)

Active sleep in neonates, also known as REM (Rapid Eye Movement) sleep, is characterized by frequent movements. During this phase, neonates exhibit various forms of activity, including facial twitches, limb movements, and occasional vocalizations. This stage of sleep is integral to the development of the brain and reflects the ongoing maturation of the nervous system. The presence of eye movements, often rapid and irregular, distinguishes active sleep from quiet or non-REM sleep, where movements are typically minimal.

Understanding these characteristics is crucial for interpreting sleep patterns in neonates, as they can impact overall development and health monitoring. This knowledge helps differentiate between the various stages of sleep in neonates, allowing for a better understanding of their sleep cycles and associated behaviors.
