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","C","E"]
Explanation
Choice A rationale
Pumping up the vacuum manually to the pressure indicated on the pump is a standard procedure but doesn't directly minimize liability.
Choice B rationale
Recognizing cup detachment (pop off) as a warning sign is critical, as it indicates excessive force or poor positioning, which can lead to fetal or maternal injury.
Choice C rationale
Limiting the cup's attachment to the fetal head to 5 to 10 minutes reduces the risk of scalp injury and other complications, thus minimizing liability.
Choice D rationale
Timing the procedure from insertion of the cup into the vagina until the birth is a guideline but doesn't specifically address liability concerns.
Choice E rationale
Releasing pressure between contractions prevents continuous suction on the fetal head, reducing the risk of injury and thereby minimizing liability.
Correct Answer is A
Explanation
Choice A rationale
History of preterm birth is the principal risk factor for predicting preterm birth. Previous preterm births significantly increase the likelihood of subsequent preterm deliveries due to
underlying etiological factors.
Choice B rationale
Low prepregnancy weight is a risk factor but not as significant as a history of preterm birth. It can contribute to complications in pregnancy but does not have the same predictive value.
Choice C rationale
Smoking during pregnancy increases the risk of preterm birth but is not the principal risk factor. It is a modifiable behavior that contributes to poor pregnancy outcomes.
Choice D rationale
Obesity can impact pregnancy outcomes but is not the principal risk factor for preterm birth. It is associated with other complications rather than directly predicting preterm delivery.
