Physiology
Decreases surface tension of the alveoli
Surfactant
Tool to measure gestational age
Ballard score
Liquid turning into vapor
Evaporation
When a newborn takes its first breath, air inflates and expands the lungs and increases OR decreases blood flow through pulmonary circulation
Increases
very common, occurs after 24 hours
physiologic jaundice
Increases systemic vascular resistance
Cord clamping
How far the baby's hand can be flexed toward the wrist
Square window test
Heat loss that occurs when a newborn is placed on a cool surface, such as a scale
Conduction
Fetal lungs contain a substance called what, which aids in maintaining adequate respiratory function by allowing for expansion of alveoli.
surfactant
after 24 hours, inadequate fluid intake
breastfeeding jaundice
Promotes formation of clotting factors
Vitamin K
Crossing the arm over the body towards the neck
Scarf sign
Heat loss that occurs when air flows through the room (room temperature, draft)
Convection
With the first breath, the newborn is exposed to oxygen, and the initiation of ventilation causes an increase OR decrease in pulmonary vascular resistance
Decrease
not common, factors in breastmilk interfering with bilirubin metabolism, resolves by 12 weeks
breastmilk jaundice
Byproduct of broken down RBCs
Bilirubin
Soft, fine hair covering the fetus
Lanugo
Loss of heat to object nearby
Radiation
Shunt located in the liver, connects the umbilical vein to the inferior vena cava.
ductus venosus
presents within first 24 hours
pathologic jaundice
Treatment of jaundice
Phototherapy
The Ballard score measures these two things
Neuromuscular and physical maturity
The inability to activate their muscles to shiver requires the newborn to depend on this
nonshivering thermogenesis in brown adipose tissue
There are two shunts in the fetal heart called what
the ductus arteriosus and the foramen ovale
Babies at risk for pathologic jaundice, name 2 reasons
blood incompatibility with mothers (Rh or ABO), traumatic delivery, premature, East Asian race, positive coombs test
