Why is jaundice a common problem in newborns? Group of answer choices Babies are yellow due to low blood count. Babies spend a lot of time in the amniotic fluid turning them yellow. Babies livers are releasing yellow pigment into the skin. Babies have low liver function at birth resulting in bilirubin staying in circulation.

Step 1
Jaundice in newborns is primarily caused by the accumulation of bilirubin in the blood. Bilirubin is a yellow pigment that is produced when the body breaks down old red blood cells. Show more…

Martin and Kim were both twenty-five when they had Michael, their first child. Kim remained very healthy during her pregnancy and went into labor at 9:00 p.m., just 3 days after her due date. Delivery went quite smoothly, and that evening, mother and child rested comfortably. Two days later, Kim and Michael were released from the hospital. That evening at feeding time, Kim noticed that the whites of Michael's eyes seemed just slightly yellow, a condition that worsened noticeably by the next morning. Kim decided to bring the newborn into the ER the next evening. Upon examining Michael, you inform Martin and Kim that the infant has neonatal jaundice, a condition quite common in newborns and one that need not cause them too much concern. You ask the parents to follow up with Michael's pediatrician in order to monitor blood bilirubin concentration until the bilirubin concentration drops into the normal range. Diagnosis: Jaundice. Questions for understanding: 1). What is jaundice? What is it caused by? Which of Michael's organs is responsible for this condition? 2). What is the treatment for newborn jaundice? 3). Why did Michael's skin turn yellow? What normally happens in healthy newborns without jaundice?

A 23-year-old, group O woman gave birth to a full-term, group A infant, her first child. Approximately 36 hours after delivery, the infant appeared slightly jaundiced. The serum bilirubin level was slightly increased, and the direct antiglobulin test (DAT) was negative. The infant's peripheral blood smear showed increased numbers of spherocytes and nucleated RBCs. Questions: - What is this infant's most likely diagnosis? - What is the most likely cause? - What is the basis for diagnosis? - What other tests should be performed?

The distribution of hemoglobin among newborns is approximately normal, with a mean of 17 g/dL and SD of 3 g/dL. Values within the middle 95% of the distribution are considered normal. What is the normal range of hemoglobin for newborns? b. A neonatologist treats newborns if their hemoglobin level is outside the middle 85% of the distribution. What are the upper and lower levels of hemoglobin that will trigger treatment? c. A newborn has hemoglobin of 25 g/dL. What percentile does this level correspond to in this population? (For example, 70% percentile would mean that 70% of the neonates have lower hemoglobin levels, and 30% have higher levels than this newborn.) d. What proportion of newborns has hemoglobin exceeding 23 g/dL? e. What proportion of newborns has hemoglobin between 15 to 20 g/dL?
