Painless Vaginal Bleeding at 35 Weeks and a Request for Vaginal Exam
A 34-year-old G3P2 at 35 weeks’ gestation arrives by car after a sudden gush of bright red vaginal bleeding at home. She denies pain and says the bleeding has slowed to a trickle. Vital signs: blood pressure 98/62, heart rate 122, respirations 22, SpO2 98%. Uterus is soft and nontender; fetal heart rate is 155 beats/min with moderate variability. The obstetric resident is busy and asks you to perform a sterile vaginal examination to see whether she is dilated. The patient has had one prior cesarean birth and an ultrasound report in the chart that is not yet reviewed. You have two IV lines started and have drawn a type and screen.
1. What is the priority concern, and why should the vaginal exam be avoided?
Read the worked answer
Painless bright red vaginal bleeding in late pregnancy should be treated as placenta previa until imaging proves otherwise, especially with a prior cesarean. A digital vaginal exam can disrupt the placenta and cause catastrophic hemorrhage; it is contraindicated when previa is suspected. The soft, nontender uterus makes abruption less likely, though not impossible. The fetal heart rate is currently reassuring, but maternal tachycardia suggests volume loss. I would review the ultrasound report before any exam, keep the patient on bed rest, and tell the resident I cannot perform the exam without a documented ultrasound excluding previa and a provider at the bedside.
2. What immediate interventions and monitoring do you initiate while awaiting the provider?

I would place the patient in a left lateral tilt, maintain IV access with two large-bore lines, draw type and screen/crossmatch, and give isotonic crystalloid per protocol while watching for overload. Continuous fetal monitoring and maternal vital signs every 5–15 minutes; count and weigh pads; keep the patient NPO; prepare for emergency cesarean if bleeding increases or fetal status deteriorates. I would notify the charge nurse, blood bank, anesthesia, and neonatal team. No vaginal or rectal exams, no enemas, and no ambulation to the bathroom. I would document bleeding amount, fetal tracing, and interventions. If the patient becomes hypotensive or the FHR shows late decelerations or bradycardia, I would call a code obstetric emergency.
3. How do you respond to the resident and communicate the urgency?
Read the worked answer
I would be direct and respectful: “I am not able to do the vaginal exam because the chart suggests placenta previa and the exam could cause severe hemorrhage. Please review the ultrasound and come to the bedside.” I would offer the objective data: prior cesarean, painless bright red bleeding, soft uterus, maternal tachycardia. If the resident still insists, I would escalate to the attending obstetrician and charge nurse and document the conversation. The goal is not to win an argument but to prevent harm; the exam can wait until previa is excluded by imaging.
