Study Notes

Adjustment to Extrauterine Life

At birth, the body undergoes significant changes to adapt to extrauterine life
Respirations are stimulated by chilling, chemical changes in the blood, and sensory/physical stimuli
The first breath opens the alveoli, marking the beginning of air exchange and independent existence
Cardiopulmonary interdependence is initiated shortly after birth

Digestive System

The newborn's ability to metabolize food is limited due to immaturity of the digestive system
Deficiencies in pancreatic and liver enzymes contribute to this limitation
Kidneys are structurally developed but have limited urine concentrating and fluid balancing abilities

Microbiomes

At birth, the newborn's microbiota resembles the mother's vagina or skin (depending on delivery method)
Postpartum nurses can support the developing microbiome through breastfeeding, safe skin care, and parent education
Breastfeeding supports the gut microbiome, which plays a crucial role in maintaining metabolism, immune responses, and intestinal mucosa development
Mixed formula and breastfeeding results in a gut microbiome similar to exclusive formula feeding
An altered or absent microbiome (dysbiosis) may influence health patterns and the development of disorders later in life

Newborn Care and Development

Phase 3 care of the newborn involves assessing physical characteristics and nursing care by body system
The nervous system directs most bodily activities, and newborns exhibit reflexes that help them survive (e.g., blinking, sneezing, gagging, sucking, grasping)
Newborns can move their arms and legs vigorously but lack control; they also exhibit a head lag when lifted due to lack of head control
