Which finding would best differentiate abruptio placentae from placenta previa in a bleeding pregnant patient?

• A. Painless vaginal bleeding
• B. Uterine tenderness
• C. Bright red bleeding
• D. Normal fetal heart rate

Answer: (B)

Painful vaginal bleeding with uterine tenderness distinguishes placental abruption from placenta previa. When the placenta prematurely separates from the uterine wall, the uterus often becomes tender and hypertonic as contractions occur, and bleeding can be dark or internal. In contrast, placenta previa involves placenta tissue near or over the cervical os and typically presents with painless vaginal bleeding because the bleeding is not driven by uterine contractions or separation. While bright red bleeding can occur in either condition and a normal fetal heart rate doesn’t by itself separate them, the presence of uterine tenderness is the clearest clue pointing toward abruption. This distinction guides urgent management, with abruption requiring rapid stabilization and delivery consideration, while previa management centers on bleeding control and planning delivery based on gestational age and maternal-fetal status.
