OBG · Placental disorders
Sample itemWhich bleeding pattern is most typical of placenta previa?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Painless bright-red bleeding late in pregnancy
Placenta previa often causes painless bright-red antepartum bleeding because the placenta overlies or approaches the cervical opening; digital examination is avoided until location is known.
Option by option
A. Painless bright-red bleeding late in pregnancy (correct)
Correct: painless late-pregnancy bleeding suggests placenta previa.
B. Painful rigid uterus after trauma
Painful rigid uterus suggests placental abruption.
C. Bleeding only after delivery
Postpartum bleeding has a different differential.
D. Bleeding with ear pain
Ear pain is unrelated to placental position.
