Question

Quizplus · Accepted Answer

The initial and most critical physiologic change required of the newborn after birth is the initiation and maintenance of respirations. Without oxygen, other bodily functions cannot continue, making breathing the most essential physiological change for the newborn. While the closure of fetal shunts, full immune function, and maintenance of temperature are all important, they can wait a few minutes after birth, whereas the initiation of respirations cannot be delayed.
