A 35-year-old pregnant woman with irregular periods, G4 T2 PO A1 L2 is 28 weeks pregnant by the last ultrasound, when she experiences bright red and painless vaginal bleeding, fetal contour is easily assessed, and uterine tone is normal. On her arrival at the hospital, what would be an expected diagnostic procedure or test to confirm the diagnosis?
Select one:
Vaginal Ultrasound for placental location
Amniocentesis for fetal lung maturity
Abdominal Ultrasound for placental location
Contraction stress test (CST)

b. This is not typically done for diagnosis of painless vaginal bleeding.
c. While an abdominal ultrasound can also determine the location of the placenta, a vaginal ultrasound is more accurate for this purpose.
