A nurse is reviewing the differences between placenta previa and abruptio placentae with a group of nursing students.Which of the following statements accurately differentiates placenta previa from abruptio placentae?

Placenta previa is characterized by sudden onset of severe abdominal pain and uterine tenderness, while abruptio placentae is associated with painless bleeding.

Placenta previa typically presents with severe pain and contractions, whereas abruptio placentae involves painless bleeding without contractions.

Placenta previa involves the placenta partially or completely covering the cervix, whereas abruptio placentae involves the premature separation of the placenta from the uterine wall.

Placenta previa usually results in a higher risk of maternal hypertension, while abruptio placentae is commonly associated with a low-risk pregnancy.
