单项选择题

A．Weight loss of 25%.
B．Birth weight of 2,000 to 2,500 g.
C．Weight loss then return to birth weight.
D．Weight gain of 25%.
答案
参考答案：C
解析：
Babies lose approximately 10% of their birth weight during the first 3 or 4 days, due to the loss of excess extracellular fluids and meconium as well as limited oral intake, until breast-feeding is established. Return to birth weight should occur within 10 days after birth. Normal birth weights range from 2,700 to 4,000g.
