Explanation

(A) Respiratory distress syndrome occurs in the newborn, not the fetus. It may be treated postnatally with surfactant therapy. (B) Betamethasone is a corticosteroid, not an anti-infective drug; therefore, its use would not prevent uterine infection. (C) Betamethasone binds with glucocorticoid receptors in alveolar cells to increase production of surfactant, thus increasing lung maturity in the preterm fetus. (D) Betamethasone does not affect uteroplacental circulatory exchange.
