Answer to Question 1

ANS: A
To reduce the incidence of HBV in children and its serious consequences in adulthood, the first of three doses is recommended soon after birth and before hospital discharge. Between 12 and 15 months is too late. The recommendation is for the first dose to be given soon after birth. It is recommended for all newborns. Newborns born to mothers who are HBV surface antigen positive should be given the vaccine within 12 hours of birth. They also should be given hepatitis B immune globulin.

Answer to Question 2

ANS: A
Radiation is the loss of heat to a cooler solid object. The cold air from either the window or the air conditioner will cool the incubator walls and subsequently the newborn's body. Conduction involves the loss of heat from the body because of direct contact of the skin with a cooler object. Convection is the loss of heat similar to conduction but aided by air currents. Evaporation is the loss of heat through moisture. The newborn should be quickly dried of the amniotic fluid.
