A 32-week-pregnant woman with a history of two previous mid-trimester aboions presents with regular contraction of the uterus. The cervix is 2 cm dilated. All the following are done except
## **Core Concept**
The clinical scenario describes a pregnant woman at 32 weeks of gestation with a history of two previous mid-trimester abortions, now presenting with regular uterine contractions and 2 cm cervical dilation. This presentation suggests **preterm labor**, a condition where a woman goes into labor before 37 weeks of gestation. The history of mid-trimester abortions may indicate a possible **cervical insufficiency** or **incompetent cervix**, which is a condition where the cervix dilates prematurely, often leading to preterm birth or pregnancy loss.
## **Why the Correct Answer is Right**
Given the context, the management of preterm labor, especially with suspected cervical insufficiency, involves measures to delay birth if possible, to allow for fetal maturation and administration of corticosteroids to enhance fetal lung maturity. The options provided are not explicitly listed, but generally, management strategies include **tocolytic therapy** to temporarily halt contractions, **corticosteroids** for fetal lung maturity, and possibly **cerclage** (a surgical procedure to close the cervix) in cases of cervical insufficiency.
## **Why Each Wrong Option is Incorrect**
Without specific details on options A, B, C, and D, a general approach to why an option might be incorrect in this context:
- **Option A:** If this involved immediate delivery without assessing fetal lung maturity or without attempting to delay labor, it might be incorrect because delaying delivery can be beneficial.
- **Option B:** If this involved administering corticosteroids for fetal lung maturity, it would be a correct approach and thus not the answer.
- **Option C:** If this involved a cerclage, it could be appropriate for cervical insufficiency and thus not the incorrect option.
- **Option D:** If this involved a tocolytic agent to temporarily stop contractions, it could also be an appropriate measure.
## **Clinical Pearl / High-Yield Fact**
In cases of suspected cervical insufficiency, especially with a history of painless cervical dilation leading to preterm birth, **cervical cerclage** is a key intervention that can significantly reduce the risk of preterm birth in selected patients. The decision to perform a cerclage is often based on a combination of clinical history (like prior mid-trimester losses), ultrasound findings of a short cervix, and current cervical status.
## **Correct Answer:** D.
