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.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
