单选题 Which finding is considered normal in a neonate during the first few days after birth?
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%.

【正确答案】 C

【答案解析】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.
