1. what are the five characteristics that are rated on the apgar scale? why are these important?

Explanation:

1. During delivery: Baby’s lungs are filled with fluid; pressure changes and first breath expel fluid, allowing air to enter. After delivery: Lungs inflate fully, surfactant keeps alveoli open, and they start oxygen exchange.
2. Soft skull bones (fontanels) overlap during vaginal delivery to fit through the birth canal, causing temporary pointed shape.
3. Methods include skin-to-skin contact, warm blankets, radiant warmers, and heated bassinets to prevent hypothermia.
4. Apgar scale rates Appearance (skin color), Pulse (heart rate), Grimace (reflex irritability), Activity (muscle tone), Respiration (breathing). They assess immediate newborn health and need for intervention.
