Answer:
"The baby will need an exchange transfusion with type A blood."
Step-by-step explanation:
The mother would need to be enlightened about how ABO incompatibility works and the necessary solution. She said "The baby will need an exchange transfusion with type A blood." However ABO compatibility happens when the mother has type O blood group and the neonate is either A, B, or AB and unless the bilirubin concentration reaches dangerous levels such as (~20 mg/dL or 342 umol/L), there is no need for an exchange transfusion. If an exchange transfusion does become necessary, type O blood is used or treatment with phototherapy.
