Final answer:
Amniotic fluid functions as a cushion to protect against mechanical injury and surrounds the fetus. It allows for fetal movement and promotes muscular/skeletal development.
Step-by-step explanation:
The nurse's response is based on the fact that amniotic fluid functions as a cushion to protect against mechanical injury. It surrounds and protects the fetus, allowing for easier fetal movement and promoting muscular/skeletal development. The fetus does contribute to the production of amniotic fluid, which consists of water, dissolved substances, and fetal urine. Therefore, the nurse's response is based on the knowledge that amniotic fluid provides a protective barrier for the developing baby.
