A 32-week pregnant woman is admitted with preterm labor. What is the most appropriate intervention to delay labor?

Correct Answer: A

Rationale: The correct answer is A: Administer magnesium sulfate. Magnesium sulfate is commonly used to delay preterm labor by relaxing uterine smooth muscle. It inhibits contractions and delays labor progression. It is a standard treatment to prevent preterm birth and reduce the risk of complications for both the mother and the baby. Choice B: Emergency cesarean section is not indicated for delaying preterm labor unless there are severe complications putting the mother or baby at immediate risk. Choice C: Administering a prostaglandin inhibitor may help in some cases, but magnesium sulfate is the preferred choice for delaying labor in preterm pregnancies. Choice D: Starting a Pitocin infusion would actually stimulate contractions and hasten labor, which is the opposite of what is needed in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Administer corticosteroids to promote fetal lung maturity. This is the priority intervention in preterm labor as it helps accelerate fetal lung development, reducing the risk of respiratory distress syndrome. Administering magnesium sulfate (B) is used for neuroprotection in preterm labor but is not the priority in this case. Emergency cesarean section (C) is not indicated unless there is a life-threatening situation. Performing a nonstress test (D) is important for fetal monitoring but is not the priority intervention in this scenario.

Correct Answer: B

Rationale: The correct answer is B because complete abstinence from alcohol is the safest option during pregnancy to prevent any potential harm to the fetus. This statement shows understanding of the importance of avoiding alcohol for the well-being of the baby. Choice A suggests drinking daily, which can still pose risks. Choice C implies occasional drinking is acceptable, which can still be harmful. Choice D is incorrect because alcohol should be avoided throughout pregnancy, not just in the first trimester.

Correct Answer: B

Rationale: Correct Answer: B Rationale: Co-sleeping increases the risk of sudden infant death syndrome (SIDS) and suffocation. Placing the baby in a separate crib reduces these risks. Incorrect Choices: A: Placing the baby on their back to sleep is the recommended position to reduce the risk of SIDS. C: Avoiding pillows and soft bedding in the crib reduces the risk of suffocation. D: Tummy time is important for infant development when the baby is awake.

Correct Answer: A

Rationale: The correct answer is A: Labor usually lasts 12 to 24 hours for first-time mothers. This is the most appropriate response as it provides a realistic timeframe for labor in first-time mothers, which can vary but generally falls within this range. This information prepares the patient for a potentially lengthy labor and helps manage expectations. Choice B is incorrect because stating that labor typically lasts 6 to 8 hours for first-time mothers is too short of a timeframe, which may lead to unrealistic expectations. Choice C is incorrect because it inaccurately suggests that labor for first-time mothers is usually much shorter than for those having their second child, which is not necessarily true. Choice D is incorrect because while labor can be unpredictable, stating that it usually takes less than 12 hours for first-time mothers is not accurate, as labor duration can vary greatly among individuals.
