Which obstetric condition requires avoidance of vaginal examinations?

• A. Placenta previa
• B. Ectopic pregnancy
• C. Placental abruption
• D. Molar pregnancy

Answer: (A)

Placenta previa makes a vaginal examination risky because the placenta implants near or over the cervix, so inserting fingers or a tool into the vagina can disturb the placental tissue and trigger heavy, life-threatening bleeding. To prevent that danger, clinicians avoid vaginal exams when previa is suspected or diagnosed and rely on abdominal ultrasound to locate the placenta and guide management. If the placenta previa persists and labor begins, delivery is typically planned by cesarean rather than vaginal delivery. Other obstetric conditions don’t carry this same blanket prohibition on vaginal exams. For example, in a suspected ectopic pregnancy the exam is guided by stability and clinical findings to avoid provoking rupture; in placental abruption the priority is rapid assessment and stabilization, and vaginal exams aren’t routinely helpful and can worsen bleeding; in a molar pregnancy the main concerns are different, such as risks to the mother and the need for removal of the molar tissue, rather than a near-cervical placental location dictating exam avoidance.
