A: Hyperglycemia
Answer: A: Hyperglycemia 
Explanation: Neonatal hypoglycemia is defined as a plasma glucose level below 40mg/dl. Hypoglycemia is caused by hyperinsulinemia due to hyperplasia of fetal pancreatic beta cells consequent to maternal-fetal hyperglycemia. Because the continuous supply of glucose is stopped after bih, the neonate develops hypoglycemia because of insufficient substrate. Hypoglycemia is d/t diminished production of parathormone after bih and is defined as serum calcium level less than 7mg/dl in term babies. There is a higher risk of congenital malformations in infants born to diabetic mother-25% risk when the HbA1c level in the first trimester is > 10%.
