Answer to Question 1

A
Response:
A major source of IgA is human breast milk. IgG, found in serum and interstitial fluid, crosses the placenta beginning at approximately 20 to 22 weeks' gestation. IgM is found in blood and lymph fluid and levels are generally low at birth unless there is a congenital intrauterine infection. IgE is not found in breast milk and does not play a major role in defense in the newborn.

Answer to Question 2

B
Response:
Using a warmed cloth diaper or blanket to cover any cold surface, such as a scale, that touches a newborn directly helps to prevent heat loss through conduction. Drying a newborn and promptly changing wet linens, clothes, or diapers help reduce heat loss via evaporation. Keeping the newborn out of a direct cool draft, working inside an isolette as much as possible, and minimizing the opening of portholes help prevent heat loss via convection. Keeping cribs and isolettes away from outside walls, cold windows, and air conditioners and using radiant warmers while transporting newborns and performing procedures will help reduce heat loss via radiation.
