I share your view that this is a somewhat far fetched scenario given that, reportedly, her membrane had ruptured, and that this posed a significant risk of infection. I do know that many successful child-births can take a long time and that induction is often used to accelerate the process, so the suspicion has to be that this was not done here because it was known the foetus was unviable and so that an induction at that time could be construed as an abortion.

Premature rupture of membranes (PROM) is a condition that occurs in pregnancy when there is rupture of the membranes (rupture of the amniotic sac and chorion) more than an hour before the onset of labor. PROM is prolonged when it occurs more than 18 hours before labor. PROM is preterm (PPROM) when it occurs before 37 weeks gestation. Risk factors for PROM can be a bacterial infection, smoking, or anatomic defect in the structure of the amniotic sac, uterus, or cervix. In some cases, the rupture can spontaneously heal, but in most cases of PROM, labor begins within 48 hours. When this occurs, it is necessary that the mother receives treatment to avoid possible infection in the newborn.

... Current obstetrical management includes an induction of labor at approximately 12 hours if it has not already begun though many physicians believe it to be safe to induce labor immediately, and consideration of Group B Streptococcal prophylaxis at 18 hours.

Infection

• Maternal: If chorioamnionitis [inflammation of the amniotic sac] is present at the time of PPROM, antibiotic therapy is usually given to avoid sepsis, and delivery is indicated. If chorioamnionitis is not present, prompt antibiotic therapy can significantly delay delivery, giving the fetus crucial additional time to mature. In preterm premature rupture of membranes (PPROM), antibiotic therapy should be given to decrease the risk of sepsis. Ampicillin or erythromycin should be administered for 7 days
  
• Fetal: If the GBS status of the mother is not known, Penicillin or other antibiotics may be administered for prophylaxis against vertical transmission of Group B streptococcal infection.
