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","B","C","D","E"]
Explanation
Choice A rationale
Hypertensive disorders, such as preeclampsia, increase the risk of placental abruption. They can cause changes in the blood vessels of the placenta, reducing blood flow and increasing the likelihood of separation.
Choice B rationale
Uterine fibroids, which are noncancerous growths in the uterus, can interfere with the proper attachment of the placenta, raising the risk of placental abruption.
Choice C rationale
Cigarette smoking contributes to placental abruption by reducing oxygen supply to the placenta, causing placental insufficiency and increasing the risk of premature separation.
Choice D rationale
Abdominal trauma, such as from a fall or car accident, can cause mechanical disruption of the placenta, leading to abruption.
Choice E rationale
Methamphetamine use can cause vasoconstriction and hypertension, which compromise placental blood flow and increase the risk of abruption.
Correct Answer is ["A","B","D","E"]
Explanation
Choice A rationale
Impaired intellectual development in children born to mothers with diabetes can occur due to fluctuating blood glucose levels, which can affect brain development.
Choice B rationale
Development of metabolic syndrome is more likely in children born to mothers with diabetes due to genetic predispositions and prenatal exposure to hyperglycemia.
Choice C rationale
Shoulder injury related to birth size, although a possible immediate complication, is not typically considered a long-term effect of maternal diabetes.
Choice D rationale
Changes in genetic expression can occur due to epigenetic modifications from exposure to maternal diabetes, potentially leading to various health issues later in life.
Choice E rationale
Increased risk for chronic illnesses, such as type 2 diabetes and cardiovascular diseases, is higher in children born to mothers with diabetes, due to genetic and environmental factors.
