Which placental complication is described as a serious condition where the placenta detaches from the uterus?

• A. Placenta previa
• B. Placental abruption
• C. Placental accreta
• D. Uterine rupture

Answer: (B)

This item tests understanding of placental separation from the uterus. Placental abruption is the condition where the placenta detaches from the uterine wall before birth, making it a serious emergency because it can cause painful vaginal bleeding, abdominal tenderness, and fetal distress due to compromised oxygen and blood flow. Placenta previa involves a placenta located low in the uterus and tends to cause painless bleeding, not detachment. Placental accreta is when the placenta abnormally invades the uterine wall, leading to heavy bleeding at delivery rather than a premature detachment. Uterine rupture is a tear in the uterine wall, typically with sudden severe pain and signs of maternal and fetal compromise, not a straightforward placental detachment. The phrase describing detachment from the uterus points to placental abruption as the correct interpretation.
