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 B
Explanation
Choice A rationale
Decreased muscle tone is not typically associated with NAS. NAS often presents with increased muscle tone due to withdrawal symptoms.
Choice B rationale
A continuous high-pitched cry is a hallmark sign of NAS, indicating withdrawal and discomfort. This is due to overstimulation of the central nervous system.
Choice C rationale
Newborns with NAS often have difficulty sleeping due to irritability and discomfort, sleeping for shorter periods.
Choice D rationale
Tremors in NAS are typically pronounced and continuous, not just when disturbed. These tremors result from withdrawal effects on the nervous system.
Correct Answer is ["A","B","C"]
Explanation
Choice A rationale
Massaging the fundus helps to stimulate uterine contractions, reducing bleeding and promoting firmness in the uterus. Ensuring IV access is critical for administering medications and
fluids quickly.
Choice B rationale
Methylergonovine (Methergine) is used to prevent and control postpartum hemorrhage by promoting uterine contractions. Oxytocin bolus also helps stimulate contractions, preventing
further blood loss.
Choice C rationale
Carboprost tromethamine (Hemabate) is another uterotonic agent used to control severe postpartum hemorrhage by causing uterine contractions. Its use depends on the patient's
response to other treatments.
