Correct Answer is A
Explanation
Choice A rationale
Retained placental fragments are a significant risk factor for postpartum hemorrhage. If parts of the placenta remain attached to the uterine wall, it can prevent the uterus from contracting properly, leading to excessive bleeding.
Choice B rationale
Breech presentation is not a direct risk factor for postpartum hemorrhage. While it can complicate delivery, it does not directly cause hemorrhage.
Choice C rationale
Urinary tract infection is not a risk factor for postpartum hemorrhage. It can cause other complications but does not directly lead to hemorrhage.
Choice D rationale
Oligohydramnios, or low amniotic fluid, is not a risk factor for postpartum hemorrhage. It can cause complications during pregnancy but does not directly lead to hemorrhage.
