A woman in preterm labor at 30 weeks of gestation receives two 12 mg doses of betamethasone (Celestane) intramuscularly. The purpose of this pharmacologic treatment is to:
Reduce maternal and fetal tachycardia associated with terbutaline administration.
Suppress uterine contractions.
Stimulate fetal surfactant production.
Maintain adequate maternal respiratory effort and ventilation during magnesium sulfate therapy.
The Correct Answer is C
Betamethasone is a corticosteroid that enhances fetal lung maturity, which can help reduce the risk of respiratory distress syndrome and other complications in preterm infants. It does not reduce maternal and fetal tachycardia associated with terbutaline administration, suppress uterine contractions, or maintain maternal respiratory effort and ventilation during magnesium sulfate therapy.

Correct Answer is C
Explanation
Infants of diabetic mothers (IDM) are at risk of hypoglycemia because they have been exposed to high levels of glucose in utero. The fetus responds to this high glucose level by producing high levels of insulin to regulate the glucose level. After delivery, the glucose supply from the mother is cut off and the infant's insulin levels remain high, leading to hypoglycemia.
Additionally, the infant's ability to produce glucose is immature and may not be sufficient to maintain normal blood glucose levels, especially if the infant is premature or small for gestational age. Therefore, IDM requires close monitoring of their blood glucose levels to prevent and treat hypoglycemia.
