A nurse is admitting a client who is at 30 weeks of gestation and has pre-term labor.
Which of the following medications should the nurse anticipate administering to prevent fetal respiratory distress syndrome?
Betamethasone is a corticosteroid that is given to pregnant women who are at risk of preterm delivery to enhance fetal lung maturity and prevent respiratory distress syndrome. It is usually given in two doses, 24 hours apart, and takes effect within 24 hours of administration.
Normal ranges for gestational age are 37 to 42 weeks.
Preterm labor is defined as regular uterine contractions with cervical changes.
Magnesium sulfate is wrong because it is used to prevent seizures in women with severe preeclampsia or eclampsia, not to prevent respiratory distress syndrome.
Nifedipine is wrong because it is a calcium channel blocker that is used to inhibit uterine contractions and prolong pregnancy in women with preterm labor, not to prevent respiratory distress syndrome.
Indomethacin is wrong because it is a nonsteroidal anti-inflammatory drug that is used to inhibit prostaglandin synthesis and reduce uterine activity in women with preterm labor, not to prevent respiratory distress syndrome. However, it can also cause premature closure of the ductus arteriosus in the fetus and should be avoided after 32 weeks of gestation.
