18 Questions
How does phototherapy benefit newborns with jaundice?
It converts bilirubin to a soluble form, aiding in excretion.
In newborns, why does jaundice occur more frequently?
Because of an immature liver unable to excrete excess bilirubin.
What collectively dictates the risk level in newborns when assessing serum bilirubin levels?
The matched total serum bilirubin values and hours of life.
Why might newborns be categorized as high-risk on the nomogram for bilirubin levels?
Because of elevated serum bilirubin levels beyond specified thresholds.
What is the main function of exchange transfusion in newborns with jaundice?
To lower the serum bilirubin levels rapidly.
Why are preterm and low birth weight infants also included in the use of the nomogram for serum bilirubin levels?
Low birth weight infants have immature livers similar to full-term newborns.
What is the term for an excessive level of accumulated bilirubin in the blood?
Hyperbilirubinemia
What is a common finding in newborns characterized by a yellowish discoloration of the skin?
Hyperbilirubinemia
What is the main cause of high red blood cell levels in newborns?

What is the main cause of jaundice in newborns?
Hyperbilirubinemia
What is the primary way that bilirubin is excreted from the body?

What is a potential complication of hyperbilirubinemia in newborns?

Why is it essential to monitor a newborn's hydration status and output?
To ensure proper excretion of bilirubin
What can a careful family history reveal about a newborn's risk of hyperbilirubinemia?
Familial patterns of hyperbilirubinemia
What is the recommended frequency of voiding for a healthy term newborn under 1 week of age?
Equal to the number of days in age gap up to the 5th or 6th day
What is the purpose of encouraging parents to keep a log of the number of feedings, wet diapers, and stools?
To assess the infant's hydration status and monitor bilirubin excretion
