Neonatal Nurse Practitioner Practice Exam

Which of the following is NOT a function of amniotic fluid?

1. Protection from outside environmental noise

2. Providing nutrients to the fetus

3. Maintaining a constant temperature

4. Facilitating fetal lung development

The correct answer is: Providing nutrients to the fetus

The correct choice highlights that providing nutrients to the fetus is not a primary function of amniotic fluid. Amniotic fluid mainly serves several key purposes, including acting as a cushion that protects the developing fetus from physical trauma and outside environmental factors. It plays a critical role in maintaining a stable temperature within the amniotic sac, ensuring that the fetus is sheltered from extreme temperature fluctuations. Additionally, while the quantity and quality of amniotic fluid may indirectly influence fetal lung development by allowing for movement and practice of breathing, the actual nutrients the fetus requires for growth and development are primarily delivered through the placenta, not the amniotic fluid. Thus, the amniotic fluid does not supply nutrients to the fetus, distinguishing it from the other choices that accurately represent its functions.
