In placenta previa, which procedure should be avoided to prevent complications?

• A. Pelvic examination
• B. Ultrasound assessment
• C. Bed rest
• D. Vital signs monitoring

Answer: (A)

In placenta previa, the placenta is implanted low in the uterus near or over the cervix, so the cervix becomes a site of potential bleeding. Any vaginal or pelvic examination, especially a digital cervical check, can disturb the placental attachment and trigger heavy, sometimes uncontrollable bleeding. Because of this risk, such examinations are avoided until placental location is known and managed. The best way to assess without causing harm is a noninvasive ultrasound to determine where the placenta is located. While monitoring vital signs and fetal status is important and bed rest may be recommended in some cases, the key action to prevent complications is to avoid vaginal/pelvic examination.
