Final answer:
An obstetrician will suction the pharynx first in a newborn to clear any mucus or fluids and ensure proper breathing.
Step-by-step explanation:
When a newborn is born, an obstetrician will suction the pharynx, which is the back of the throat, first. This is done to remove any mucus or fluids that may interfere with the newborn's ability to breathe properly. By clearing the pharynx, the newborn's airway is opened, allowing for easier breathing.
