A nurse is assessing a client who has placenta previa and is receiving fetal monitoring. Which of the following clinical findings should the nurse expect?

Choice A rationale Variable decelerations are typically caused by umbilical cord compression, which can occur in various obstetric scenarios but are not a specific expected finding for placenta previa. In placenta previa, the primary issue is placental implantation over or near the cervical os, leading to distinct clinical manifestations. Choice B rationale Painless vaginal bleeding is the hallmark clinical finding of placenta previa. This occurs because the placenta is implanted in the lower uterine segment, potentially covering the internal cervical os. As the cervix effaces or dilates, the placenta separates from the uterine wall, leading to bleeding without the associated pain of uterine contractions. Choice C rationale A rigid abdomen is a classic sign of abruptio placentae, where the placenta prematurely detaches from the uterine wall. This causes internal bleeding and uterine spasm, leading to a board-like, tender abdomen, which is distinct from the typical presentation of placenta previa. Choice D rationale Uterine tachysystole, characterized by excessive uterine contractions, is a common finding in conditions like abruptio placentae or during labor induction. It is not typically associated with placenta previa, where the primary concern is the placental position and the risk of hemorrhage rather than abnormal contraction patterns.
