Placenta previa presents with which description?

• A. Sudden onset of painful bleeding with a rigid uterus
• B. Uterus is firm and nonrelaxed
• C. Painless vaginal bleeding with dark blood
• D. Painless vaginal bleeding with bright red blood and a soft uterus

Answer: (D)

Placenta previa presents with painless vaginal bleeding in the third trimester, and the uterus remains soft and non-tender. The bleeding is usually bright red because the placenta is bleeding from a placental edge rather than from a tightly contracting uterus. This contrasts with conditions like placental abruption, which cause sudden, painful bleeding and a tense, rigid uterus. So the description of painless vaginal bleeding with bright red blood and a soft uterus best matches placenta previa.
