A nurse is caring for a client who is at 36 weeks of gestation and who has a suspected placenta previa. Which of the following findings support this diagnosis?

A. Increasing abdominal pain with a nonrelaxed uterus: This describes Placental Abruption, where the placenta prematurely detaches from the uterine wall, causing concealed bleeding and a board-like, painful abdomen. B. Intermittent abdominal pain following passage of bloody mucus: This describes "bloody show" associated with the onset of normal labor or transition. C. Painless red vaginal bleeding: Placenta Previa occurs when the placenta implants over the cervical os. As the cervix begins to efface and dilate in the third trimester, it tears the placental vessels. The hallmark sign is sudden, bright red vaginal bleeding that is painless (the uterus remains soft). D. Abdominal pain with scant red vaginal bleeding: Pain combined with bleeding typically points toward abruption or uterine rupture, not previa.
