A 29 year old woman had just delivered a still born vaginally, following a major placental abruption. Choose the single most likely predisposing factor for developing PPH in this lady?

The key is B. DIC. [Pregnancy itself is a risk factor for DIC. Placental abruption increases the risk of

DIC further. Other causes of pregnancy related DIC are: eclampsia, retention of a dead fetus, amniotic

fluid embolism, retained placenta or bacterial sepsis].
