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
Extension of the episiotomy is not a guideline for vacuum-assisted delivery. Episiotomy extension is considered based on perineal conditions during delivery, not as a primary
guideline for vacuum procedures.
Choice B rationale
Signs of fetal compromise resolving is critical for fetal safety but isn't specific to the guidelines for a vacuum-assisted delivery. Continuous fetal monitoring assesses for compromise,
not just vacuum application.
Choice C rationale
The "three-pull" rule refers to the number of attempts allowed with the vacuum to avoid excessive force and trauma. This guideline ensures safety during the procedure, preventing
overuse of vacuum pressure.
Choice D rationale
Full anesthesia status is unrelated to the guidelines for vacuum-assisted delivery. Anesthesia choices depend on patient and procedural needs, but aren't a guideline criterion for
vacuum use.
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.
