In a pregnant patient, contractions suddenly stop. This finding is most concerning for which condition?

• A. Uterine rupture
• B. Placental abruption
• C. False labor
• D. Preterm labor

Answer: (A)

When contractions suddenly stop during labor, it signals a dangerous obstetric event because the uterus may have ruptured, compromising the uterus’s ability to contract and deliver the baby. A uterine rupture tears the uterine wall and can lead to loss of fetal oxygen, abnormal fetal heart patterns, and maternal shock if bleeding occurs. This pause in contractions is a red flag that requires urgent assessment and rapid transport to a facility with obstetric capabilities.

Other scenarios don’t fit this pattern as neatly. Placental abruption usually presents with painful vaginal bleeding and a tense, irritable uterus rather than a sudden stop in contractions. False labor involves irregular, often mild contractions that may stop with activity and do not progress toward delivery. Preterm labor features regular contractions that persist and lead to cervical changes before term, not a sudden cessation.
