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
Administering oxytocin during shoulder dystocia can exacerbate the problem by increasing uterine contractions, making it harder to deliver the baby's shoulder.
Choice B rationale
Flexing the client's thighs sharply toward her abdomen, known as the McRoberts maneuver, helps to widen the pelvis and can often resolve shoulder dystocia by changing the angle of the pelvic bones.
Choice C rationale
While applying oxygen is a standard practice to improve maternal and fetal oxygenation, it does not specifically address shoulder dystocia and is not a primary intervention.
Choice D rationale
Applying downward pressure on the fundus is contraindicated as it can worsen shoulder dystocia by further impacting the shoulder against the pelvic bone.
Correct Answer is B
Explanation
Choice A rationale
Swaddling provides warmth but doesn't address jitteriness, which may be due to hypoglycemia.
Choice B rationale
Jitteriness in a newborn can indicate hypoglycemia. Prompt glucose assessment is crucial for early detection and management.
Choice C rationale
Feeding could help with glucose levels, but without knowing the glucose status, it might not be the immediate priority.
Choice D rationale
Routine medications are important but not as urgent as addressing possible hypoglycemia in a jittery baby.
