Placenta previa presents with which pattern?

Placenta previa presents with which pattern?

• A. Abnormal placenta placement on or near the cervical os with painless third-trimester bleeding and a soft uterus
• B. Severe abdominal pain with rigid uterus
• C. Uterine tenderness with fever
• D. Preterm labor with contractions

Answer: (A)

Placenta previa occurs when the placenta implants near or over the cervical os. The key pattern is painless vaginal bleeding in the third trimester because bleeding from placental tissue near the cervix can occur without triggering strong uterine contractions. The uterus is usually soft and non-tender since there isn’t uterine contraction or irritation. This contrasts with placental abruption, which causes sudden, painful bleeding with a rigid, tender uterus; uterine infection or endometritis presents with uterine tenderness and fever; and preterm labor typically shows regular contractions with cervical changes. So the described picture—abnormal placental placement near the cervix with painless third-trimester bleeding and a soft uterus—fits placenta previa best.
