A. Induction of labor with intravenous oxytocin. Induction is contraindicated in cases of abruptio placentae with a Category III fetal heart rate tracing, as labor induction can worsen fetal distress and maternal bleeding. An immediate cesarean section is the safest intervention to prevent fetal and maternal complications.

B. An emergency cesarean section. A Category III fetal heart rate tracing with minimal variability and a prolonged deceleration indicates severe fetal distress, requiring immediate delivery. Partial abruptio placentae can cause fetal hypoxia, maternal hemorrhage, and potential fetal demise. The priority is an emergency cesarean section to ensure the best outcome for both mother and baby.

C. In-hospital fetal monitoring for 48 hours. Continuous monitoring is essential in cases of mild abruptio placentae without fetal distress, but in this case, a Category III tracing indicates an immediate threat to the fetus, making waiting inappropriate.

D. Discharge home on strict bed rest. Abruptio placentae is a serious obstetric emergency, and home management is never appropriate when fetal distress is present. Immediate intervention is necessary to prevent fetal and maternal complications.

A. Transverse fetal lie. A transverse fetal lie is related to fetal positioning and is not a direct complication of trauma. While maternal injuries can sometimes lead to abnormal fetal positioning, a car accident does not directly cause a transverse lie.

B. Preterm labor. Trauma, including a car accident, can trigger preterm labor due to stress, uterine irritation, or placental dysfunction. Uterine contractions may begin as a response to the injury, potentially leading to preterm birth.

C. Severe preeclampsia. Preeclampsia is not a direct result of trauma. It is a pregnancy-related hypertensive disorder that develops due to vascular abnormalities rather than external injury. A car accident does not increase the risk of preeclampsia.

D. Placenta previa. Placenta previa is a condition where the placenta covers the cervix, leading to painless vaginal bleeding, but it is not caused by trauma. It is a pre-existing placental abnormality rather than a complication of an auto accident.

E. Placental abruption. Trauma, such as a car accident, significantly increases the risk of placental abruption, where the placenta prematurely detaches from the uterine wall. This can cause vaginal bleeding, abdominal pain, and fetal distress, making it a critical complication to monitor for in a pregnant trauma patient.
