Which statement best distinguishes rupture from dehiscence?

Which statement best distinguishes rupture from dehiscence?

• A. Rupture is complete separation with symptoms; dehiscence is incomplete separation often found during surgery
• B. Rupture is life-threatening; dehiscence is not
• C. Rupture occurs only after vaginal birth
• D. Dehiscence always involves placenta accreta

Answer: (A)

The key idea here is how much of the uterine wall has separated and how it presents clinically. A rupture means a complete tear through all layers, producing obvious signs and symptoms such as sudden pain, heavy bleeding, fetal distress, and maternal instability. Dehiscence, by contrast, is a partial separation—an incomplete breach of the scar that may not cause obvious symptoms and is often found only during a surgical procedure like a cesarean section. This makes the statement that rupture is a complete separation with symptoms the best fit, while dehiscence is an incomplete separation often discovered during surgery. The other options don’t reliably describe the distinction: rupture isn’t defined solely by being life-threatening, dehiscence isn’t characterized by being symptom-free in all cases but often found incidentally, and neither condition is restricted to a specific timing after birth or tied to placental accreta in this context.
