Which infant has the lowest risk of developing high levels of bilirubin?
 
  a. The infant who developed a cephalohematoma
  b. The infant who was bruised during a difficult birth
  c. The infant who uses brown fat to maintain temperature
  d. The infant who is breastfed during the first hour of life

Question 2

Parents ask the nurse, What makes the opening between the baby's atriums close at birth? The nurse's response is that cardiovascular changes that cause the foramen ovale to close at birth are a direct result of:
 
  a. changes in the hepatic blood flow.
  b. increased pressure in the left atrium.
  c. increased pressure in the right atrium.
  d. decreased blood flow to the left ventricle.

Answer to Question 1

ANS: D
The infant who is fed early will be less likely to retain meconium and resorb bilirubin from the intestines back into the circulation. Cephalohematomas will release bilirubin into the system as the red blood cells die off. Bruising will release more bilirubin into the system. Brown fat is normally used to produce heat in the newborn.

Answer to Question 2

ANS: B
With the increase in the blood flow to the left atrium from the lungs, the pressure is increased, and the foramen ovale is functionally closed. The hepatic blood flow changes, but that is not the reason for the closure of the foramen ovale. The pressure in the right atrium decreases at birth. It is higher during fetal life. Blood flow increases to the left ventricle after birth.
