Final answer:
The Apgar test is a required newborn exam in all 50 states. It assesses the baby's transition from the uterus to the outside world by evaluating skin color, heart rate, reflex, muscle tone, and respiration. High scores indicate a smooth transition while lower scores may indicate distress.
Step-by-step explanation:
All babies born in the U.S. are required to undergo state-mandated newborn exams. One common exam that is required in all 50 states is the Apgar test. The Apgar test is conducted immediately after birth to assess the baby's transition from the uterus to the outside world. It evaluates five criteria: skin color, heart rate, reflex, muscle tone, and respiration, and assigns a score to each criterion. High scores indicate a smooth transition, while lower scores may indicate distress.
