Answer to Question 1

ANS: D
Because the infant is wet with amniotic fluid and blood, heat loss by evaporation occurs quickly. Radiation occurs with the transfer of heat to a cooler object that is not in direct contact with the infant. Conduction occurs when the infant comes into contact with a cold surface. The crib should be preheated to prevent this from occurring. Convection occurs when heat is transferred to the air surrounding the infant.

Answer to Question 2

ANS: B
Pressure in the fetal circulation is greatest in the right atrium, which allows right-to-left shunting that aids in bypassing the lungs during intrauterine life. The pressure increases in the left atrium after birth and will close the foramen ovale. The liver does not filter the blood during fetal life until the end. It is functioning by birth. Blood bypasses the pulmonary vein during fetal life.
