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 A
Explanation
Choice A rationale
Methylergonovine (Methergine) is used to manage postpartum hemorrhage by stimulating uterine contractions. It is especially useful in cases like this where rapid uterine tone is needed.
Choice B rationale
Magnesium sulfate is used to prevent seizures in preeclamptic patients, not to manage postpartum hemorrhage. This choice is incorrect in this context.
Choice C rationale
Carboprost-tromethamine (Hemabate) is also used for treating postpartum hemorrhage but is typically a secondary option to methylergonovine and may have more side effects.
Choice D rationale
Fresh frozen plasma (FFP) is used to replace clotting factors in cases of coagulopathy, not as a primary intervention for postpartum hemorrhage in this patient.
Correct Answer is C
Explanation
Choice A rationale
While intravenous antibiotics are given during labor to prevent GBS transmission to the baby, it is not administered at home but in the hospital when labor begins.
Choice B rationale
GBS does not significantly increase the risk of intrauterine infection that requires daily temperature checks; it primarily poses a risk of neonatal infection during delivery.
Choice C rationale
GBS bacteria reside in the vagina and can be transmitted to the baby during delivery. Administering antibiotics during labor helps protect the baby from serious GBS-related illnesses.
Choice D rationale
GBS does not cause scarlet fever or the symptoms described; those are caused by different bacteria, namely Streptococcus pyogenes. .
