A gravida 3 client reveals that she gave birth to her first child vaginally and her second child by cesarean birth due to a complete placenta previa. The client agrees to attempt a vaginal birth after cesarean (VBAC) and presents at the local hospital in early labor, 3 to 4 cm dilated, 80% effaced, and at +1 station. The nurse anticipates the possibility of VBAC based on which type of incision noted in the record?
