Final answer:
Terbutaline is used to halt the contractions associated with preterm labor, which is a true statement. Oxytocin is the hormone that primarily causes labor contractions. Preterm labor management, including the use of terbutaline, aims to delay labor if the fetus would benefit from further development.
Step-by-step explanation:
Terbutaline would be used to halt the contractions associated with preterm labor, and the answer to the statement is a) True. Terbutaline is a medication that can be prescribed to stop or reduce premature uterine contractions to delay premature birth. The hormone primarily responsible for the contractions during labor is oxytocin, which stimulates the uterine muscles to contract. Before the baby and placenta are expelled, the cervix must dilate, and the body prepares for this process through various physiological changes.
In cases like the one described with Devin who is 35 weeks pregnant and experiencing mild contractions, it's crucial to differentiate between false labor and the onset of actual labor. The presence of an intact mucus plug and an undilated cervix suggest that while contractions are occurring, labor may not have begun. Preterm labor management often involves medications like terbutaline to reduce contractions and delay labor, especially if the fetus would benefit from further development in the uterus.
