Final answer:
Conditions that must be present before labor induction can occur include a favorable cervix and fetal distress.
Step-by-step explanation:
Before induction can take place, there are certain conditions that must be present. One of these conditions is a favorable cervix, meaning that the cervix is thinning and dilating. Another condition is fetal distress, which can be indicated by abnormal fetal heart rate patterns or other signs of distress in the baby. However, placenta previa and gestational diabetes are not conditions that necessarily need to be present for induction to take place.
