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 scenario presents a patient with a history of recurrent mid-trimester abortions, indicating a possible underlying condition that increases her risk for preterm labor. The patient's current presentation of regular uterine contractions and cervical dilation suggests an impending preterm birth.
**Why the Correct Answer is Right**
In cases of preterm labor, the primary goal is to delay or halt the labor process to prevent premature birth. A common approach involves administering tocolytic agents to relax the uterine muscles and reduce contractions. However, in this scenario, the patient's history of recurrent mid-trimester abortions and current presentation of cervical dilation suggest that the labor process is likely progressing beyond the point where tocolytic agents would be effective.
**Why Each Wrong Option is Incorrect**
* **Option A:** Administering magnesium sulfate is a common practice in preterm labor to relax the uterine muscles and reduce contractions. It is not typically contraindicated in cases of cervical dilation.
* **Option B:** Monitoring fetal heart rate is a crucial aspect of managing preterm labor to assess fetal well-being. It is an essential step in the management process.
* **Option D:** Administering corticosteroids to promote fetal lung maturity is a standard practice in preterm labor to reduce the risk of respiratory complications after birth. It is not typically contraindicated in cases of cervical dilation.
**Clinical Pearl / High-Yield Fact**
In cases of recurrent mid-trimester abortions, a possible underlying cause is a cervical insufficiency. This condition can be assessed using a cervical length measurement via transvaginal ultrasound. A cervical length of less than 25 mm is considered abnormal and may require further evaluation or intervention.
**Correct Answer: D. Administering corticosteroids to promote fetal lung maturity is typically done before the onset of labor, and in cases of preterm labor with cervical dilation, the focus shifts to managing the labor process rather than delaying it with tocolytics.**
