Final answer:
The priority assessment for fetal assessment after an Amniocentesis to assess fetal lung maturity is the baby's breathing.
Step-by-step explanation:
The priority assessment for fetal assessment after an Amniocentesis to assess fetal lung maturity is the baby's breathing. During the procedure, some amniotic fluid may be removed, and this can lead to a temporary reduction in amniotic fluid volume, potentially affecting the baby's ability to breathe. The nurse should monitor the baby for signs of respiratory distress, such as rapid breathing, grunting, or retractions.
