A client at 28 weeks' gestation with intact membranes is admitted with the following findings: contractions every 5 minutes lasting 60 seconds, 3 cm dilated, 80% effaced.
Which of the following medications will the obstetrician likely order?
Magnesium sulfate.
Morphine sulfate.
Terbutaline.
Betamethasone.
The Correct Answer is C
Choice A rationale
Magnesium sulfate is primarily used for neuroprotection in preterm infants and to prevent seizures in severe preeclampsia, not as a first-line tocolytic for preterm labor.
Choice B rationale
Morphine sulfate is an opioid analgesic used for pain management, not for inhibiting preterm labor contractions.
Choice C rationale
Terbutaline is a beta-agonist used as a tocolytic to relax uterine muscles and delay preterm labor. It helps decrease the intensity and frequency of contractions, making it suitable for managing preterm labor.
Choice D rationale
Betamethasone is a corticosteroid used to accelerate fetal lung maturity in preterm labor, not for direct contraction inhibition.

Correct Answer is C
Explanation
Choice A rationale
Prolonged labor is not directly linked to drug use and does not present as an immediate complication.
Choice B rationale
Prolapsed cord is not associated with substance abuse and lacks direct connection to this scenario.
Choice C rationale
Cocaine use heightens the risk of abruptio placentae, a serious condition where the placenta detaches prematurely.
Choice D rationale
Retained placenta is a concern but less likely than abruptio placentae in the context of cocaine use.
Correct Answer is A
Explanation
Choice A rationale
PTB is the leading cause of neonatal mortality and for antenatal hospitalization. This is accurate because preterm birth (PTB) is a significant cause of infant mortality and often
requires extended hospital stays for the management of complications.
Choice B rationale
PTBs result in increased numbers of neonatal and infant deaths and long-term neurological impairment. This is accurate because preterm births are associated with higher rates of
mortality and long-term health issues in infants.
Choice C rationale
PTL is defined as regular uterine contractions resulting in cervical changes before 37 weeks gestation. This is accurate because preterm labor (PTL) is indeed characterized by these
symptoms occurring before full-term pregnancy.
Choice D rationale
Average costs for premature/low birthweight infants are more than 10 times as high than for other newborns. This is accurate because medical care for premature and low
birthweight infants is significantly more expensive due to the need for specialized care and extended hospital stays.
