In pregnancy, when is a vaginal exam contraindicated?

• A. Uterine contractions
• B. Bleeding with unknown origin
• C. Prior cesarean
• D. Vaginal infection

Answer: (B)

In pregnancy, a vaginal examination is avoided when there is vaginal bleeding of unknown origin. The reason is that you don’t know where the bleeding is coming from—there could be placenta previa or occult placental abruption, and performing an internal exam could provoke or worsen hemorrhage and threaten both mother and fetus. The safest approach is to identify the source and placental location with imaging or a cautious speculum assessment before any internal examination is considered. Uterine contractions alone aren’t a reason to withhold an exam; assessing dilation and effacement can be important in labor management. A prior cesarean also isn’t an absolute contraindication to a vaginal exam, though care is required depending on the clinical scenario. A vaginal infection isn’t a blanket contraindication; exams can be performed with appropriate infection control and precautions as needed.
