Hyperbilirubinemia
This icterus occurs within the first 24 hours of life and usually requires intervention
What is pathologic jaundice?
Phospholipid that prevents collapse of the alveoli
What is surfactant?
Respiratory and cardiovascular
What two systems are most affected by prematurity?
Clamping of the cord and first breath
What causes the DA and FO to close in the newborn?
Adipose tissue that is oxidized in response to cold
What is brown fat?
Bilirubin that is water-soluble and nontoxic
What is conjugated/direct bilirubin?
Impaired gas exchange, chronic cough, barrel-chest, clubbing, altered absorption of ADEK vitamins
What are clinical manifestations of cystic fibrosis?
Lack of plantar creases, plentiful lanugo, poor muscle tone and abundant vernix
What are some characteristics of the premature infant?
Blood flows from the pulmonary artery to the aorta through this duct in fetal circulation
What is the ductus arteriosus?
How do we minimize cold stress in the newborn?
Direct coombs, hemoglobin, blood type or reticulocyte count
Back to sleep, no blankets, no bedsharing
What are nursing considerations for preventing SIDS?
Lack of surfactant production
Why are preterm infants at a higher risk for RDS?
Retractions, grunting and tachypnea in the full term infant shortly after birth
What is transient tachypnea of the newborn (TTN)?
Heat loss that occurs from sitting in an igloo
What is radiation?
Phototherapy and frequent feedings
What are two priority interventions for hyperbilirubinemia?
Necrosis of the respiratory endothelium, plugging the lumens with mucus
What is respiratory syncytial virus (RSV)?
Retinopathy of prematurity
What can large concentrations of oxygen cause a newborn to have?
Jittery, apnea, lethargic, cyanotic
What are symptoms of hypoglycemia?
Increasing metabolic rate, fetal position, peripheral vasoconstriction
How does the newborn conserve heat?
Accelerated breakdown of RBCs, delay in bowel excretion, breastfeeding, cephalohematoma
What are some causes of jaundice?
Leakage of fluid and fibrin from the pulmonary capillaries form hyaline membranes, giving the chest x-ray this look for patients with RDS
What is a ground glass appearance?
Clustering care, skin-to-skin, nonnutritive sucking
What are some nursing interventions to promote growth and development of the preterm infant?
Common head injury that occurs from a lengthy or traumatic pushing phase of labor
What is caput succedaneum?
Heat loss from a fan or open window when it's breezy outside
What is convection?
