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 rationaleVariable decelerations are associated with umbilical cord compression, not placenta previa. In placenta previa, the placenta covers the cervical os, but it does not typically cause variable decelerations on fetal monitoring.Choice B rationalePainless vaginal bleeding is a hallmark sign of placenta previa. This occurs because the placenta is located near or over the cervical os, leading to bleeding when the cervix dilates or effaces.Choice C rationaleA rigid abdomen is more indicative of placental abruption, where the placenta detaches prematurely from the uterine wall, causing pain and a tense abdomen, not typically seen in placenta previa.Choice D rationaleUterine tachysystole is characterized by excessive uterine contractions and is not a clinical finding related to placenta previa. Tachysystole often results from excessive oxytocin use or other uterine stimulants.
