Final answer:
An Apgar score is a test administered to infants immediately after birth to evaluate their transition from the uterus. It assesses the baby's appearance, pulse, grimace, activity, and respiration. High scores indicate a smooth transition.
Step-by-step explanation:
The subject of this question is Biology. An Apgar score is a simple test administered to an infant immediately after birth to evaluate its transition from the uterus to the outside world. It assesses the baby on five criteria: appearance (skin color), pulse (heart rate), grimace (reflex), activity (muscle tone), and respiration. Each criterion is assigned a score of 0, 1, or 2, and the scores are taken at 1 minute and 5 minutes after birth. Higher scores indicate a smooth transition, while lower scores may indicate distress.
