Which medications are used for neonatal lung maturation?

The correct answer focuses on the medications that are specifically used to promote lung maturity in neonates. Betamethasone is a corticosteroid administered to pregnant women at risk of preterm delivery. This medication accelerates fetal lung development by promoting the production of surfactant, which is essential for reducing surface tension in the alveoli and improving lung function after birth. Survanta, on the other hand, is a surfactant replacement therapy administered directly to neonates after birth, particularly those born prematurely, to help keep the lungs open and prevent respiratory distress syndrome (RDS).

Both of these agents play a crucial role in the management of preterm infants at risk for RDS. Betamethasone works in utero to prepare the lungs prior to delivery, while Survanta acts postnatally to address issues related to lung maturity and function. This combination directly targets the physiological challenges faced by premature neonates.

The other options consist of medications that are not relevant to neonatal lung maturation. Oxytocin and Nifedipine are involved in labor management while Cervidil and Methergine relate to uterine contractions and postpartum hemorrhage management, respectively. Magnesium sulfate is often used for seizure prophylaxis in pregnant women
