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 rationale A negative blood type, specifically Rh-negative, is significant for potential Rh incompatibility with an Rh-positive fetus, requiring RhoGAM administration. However, it is a manageable condition and not an immediate emergency at 36 weeks unless sensitization has already occurred, which is not indicated by the finding itself. Choice B rationale Copious leukorrhea, a white or yellowish vaginal discharge, is a common and normal physiological finding during pregnancy due to increased estrogen levels and blood flow to the pelvic area. It is typically non-pruritic and non-odorous, indicating no immediate pathological concern that warrants urgent reporting. Choice C rationale A positive rubella serum antibody titer indicates immunity to rubella, either from prior infection or vaccination. This is a desirable outcome as it signifies protection against a teratogenic infection during pregnancy and therefore does not require immediate reporting to the provider. Choice D rationale A blood pressure of 144/94 mm/Hg in the left arm indicates gestational hypertension or preeclampsia, especially at 36 weeks' gestation. This reading is significantly elevated above the normal range (typically less than 120/80 mm/Hg) and warrants immediate reporting to the provider due to potential risks of maternal complications such as eclampsia, HELLP syndrome, or fetal compromise.
