The infant who is small for gestational age (intrauterine growth restriction) is prone to hypoglycemia because of
a. decreased glucose utilization at birth
b. poor sucking
c. reduced glycogen reserve
d. respiratory distress
C
The neonate who is small for gestational age has reduced glycogen stores. During intrauterine life, the nutrients available to these infants were necessarily channeled toward growth rather than being set aside for glycogen storage. At birth, then, little glycogen reserve is available to meet the infant's metabolic needs. Neonates who are small for gestational age require more glucose during the transition to extrauterine life. While poor sucking will impact on obtaining sufficient glucose for metabolic functions, it does not address the reduced glycogen stores at birth. Respiratory distress may be a complication of small for gestational age neonates, but it is not what makes them prone to hypoglycemia.
