A pregnant woman is just admitted to the emergency room after a head on auto accident. Her body appears to be uninjured. The nurse carefully monitors the woman for which complication(s) of pregnancy? (Select all that apply)

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. Quantity of vaginal bleeding. While both placenta previa and abruptio placentae can cause vaginal bleeding, the amount alone does not differentiate between the two conditions. Placenta previa typically causes painless, bright red bleeding, whereas abruptio placentae often presents with concealed or variable bleeding, making quantity an unreliable distinguishing factor.

B. Presence of abdominal pain. Abdominal pain is a key differentiating factor. Placenta previa is characterized by painless vaginal bleeding, while abruptio placentae causes sudden, severe abdominal pain due to placental detachment and uterine muscle irritation. This makes the presence or absence of pain an important assessment finding.

C. Leopold's maneuver results. While Leopold’s maneuvers help determine fetal position and presentation, they do not provide definitive information about the location of the placenta or differentiate between placenta previa and abruptio placentae. Ultrasound is a more reliable diagnostic tool for this purpose.

D. Maternal blood pressure. Although abruptio placentae can lead to hypovolemic shock and blood pressure changes due to hemorrhage, maternal blood pressure alone is not a primary diagnostic criterion for differentiating between the two conditions. Other clinical findings such as pain and ultrasound results are more useful for diagnosis.
