Which action is emphasized when placenta previa is suspected to ensure safe evaluation?

• A. Proceed with vaginal examination with sterile technique
• B. Administer tocolytics and observe
• C. Avoid vaginal examination and rely on ultrasound confirmation; consult OB
• D. Schedule an emergent cesarean without imaging

Answer: (C)

Avoid a vaginal examination when placenta previa is suspected because probing the cervix can trigger heavy bleeding if the placenta is covering or near the os. The safest first step is to determine placental location noninvasively with ultrasound and involve obstetrics for proper management. Ultrasound safely confirms where the placenta lies relative to the cervical opening, guiding delivery planning (often cesarean) if previa is present. Tocolytics and observation don’t address placental position and could delay needed care, and performing an emergent cesarean without imaging risks unnecessary surgery without knowing the placental position.
