Final answer:
The question involves a pregnant woman with preterm labor symptoms; the provided options are not directly relevant to the scenario. It's important to focus on managing preterm labor and ensuring the safety and health of both mother and child.
Step-by-step explanation:
The student's question is related to a 29-year-old pregnant woman presenting with preterm labor. None of the options provided directly relate to the scenario described, which involves a single pregnancy with preterm labor symptoms (dilation of the cervix to 3 cm and a gestational age of 24 weeks). The options provided discuss twin pregnancies and potential complications which do not seem pertinent to the situation at hand based on the information given.
The common intervention for preterm labor is to administer medications to halt the contractions or to speed up fetal lung development if birth appears imminent. However, pregnancy complications such as Rh-isoimmunization may require additional interventions. It is crucial to ensure the well-being of both the mother and the baby in such situations through close monitoring and medical care.
