Which symptom would most warrant immediate evaluation for placental abruption?

• A. Mild vaginal bleeding with no pain
• B. Severe abdominal pain with uterine tenderness
• C. Normal fetal movement
• D. No uterine changes

Answer: (B)

Severe abdominal pain with uterine tenderness is the most urgent sign for placental abruption because it reflects active placental separation with a painful, hypertonic uterus. When the placenta detaches, bleeding into the uterine space and the uterus’s myometrium contracting against it produce sudden, intense pain and a rigid or tender uterus. This scenario carries a high risk of fetal distress and significant maternal blood loss, so it mandates immediate evaluation with continuous fetal monitoring, maternal vital signs, and prompt decisions about management, including readiness for delivery if instability or distress occurs. Mild vaginal bleeding with no pain is more suggestive of other issues like placenta previa and is less consistent with abruptio placentae. Normal fetal movement is reassuring but can occur even with an abruption in early stages, so it doesn’t rule it out. No uterine changes argue against an ongoing abruption and aren’t an urgent red flag.
