Which client is at greatest risk for early PPH?
Correct Answer: B
Rationale: The correct answer is B because a woman with severe preeclampsia on magnesium sulfate is at the greatest risk for early postpartum hemorrhage (PPH) due to the increased risk of placental abruption, coagulopathy, and uterine atony associated with preeclampsia and magnesium sulfate use. Preeclampsia can lead to poor placental perfusion, increasing the risk of hemorrhage during and after delivery. Magnesium sulfate can also affect blood clotting mechanisms, further increasing the risk of excessive bleeding. The other choices are less likely to be at greatest risk for early PPH. Choice A involves a primiparous woman with cesarean delivery, which may have controlled bleeding. Choice C is a multiparous woman with a relatively short labor duration, which is not a significant risk factor for early PPH. Choice D is a primigravida with preterm twins, which does not inherently increase the risk of early PPH
