Final answer:
Most C-sections are performed when unexpected problems occur during delivery, such as breech presentation, placenta previa, and fetal distress.
Step-by-step explanation:
Most C-sections are done when unexpected problems happen during delivery. These include:
- Breech presentation: In some cases, when the baby is positioned buttocks down instead of head down, a C-section may be necessary to safely deliver the baby.
- Placenta previa: If the placenta partially or completely covers the opening of the cervix, causing profuse vaginal bleeding after week 24 of pregnancy, a C-section may be the preferred method of delivery.
- Fetal distress: If the baby's heart rate is abnormal, indicating a lack of oxygen, an emergency C-section may be performed to ensure the safety of the baby.
