The nurse identifies the following assessment findings in a client who is 36 weeks' gestation.Which should be immediately reported to the provider?

Choice A rationaleA positive rubella serum antibody titer indicates immunity to rubella infection, which is protective during pregnancy. It is not an abnormal finding and does not require immediate reporting. Rubella immunity is important to prevent congenital rubella syndrome in the fetus, a severe condition causing defects such as deafness or cardiac anomalies.Choice B rationaleBlood pressure of 144/94 mmHg is elevated and indicates gestational hypertension, which could progress to preeclampsia if not managed. Preeclampsia can lead to complications such as eclampsia, placental abruption, or maternal and fetal mortality. Normal blood pressure during pregnancy is less than 140/90 mmHg, making this finding critical to report.Choice C rationaleCopious leukorrhea is a common physiological change in pregnancy due to increased estrogen levels and vascularity. It is usually benign and protective, preventing infections by maintaining a mildly acidic environment in the vagina. This finding does not warrant immediate concern unless associated with infection symptoms.Choice D rationaleAn O-negative blood type requires administration of Rh immunoglobulin to prevent Rh isoimmunization, but this is routinely managed in pregnancy. It is not an urgent issue unless there are concerns about fetomaternal hemorrhage or alloimmunization, which could harm an Rh-positive fetus.
