Final answer:
In a case of placental abruption with a deteriorating fetal condition necessitating an emergent C-section, dangerous risks for both the mother and baby include postpartum hemorrhage for the mother and oxygen deprivation leading to fetal distress or demise for the baby.
Step-by-step explanation:
In a case of placental abruption, a condition where the placenta separates from the uterus before delivery, there are dangerous risks for both the mother and baby.
For the mother, one risk is postpartum hemorrhage if fragments of the placenta remain in the uterus. This can lead to excessive bleeding. Another risk is infection if the placenta is not fully expelled.
For the baby, a deteriorating fetal condition necessitating an emergent C-section may indicate oxygen deprivation due to the separation of the placenta. This can result in fetal distress or even fetal demise if not promptly addressed.
