A nurse is discussing the importance of good nutrition to a young pregnant client. The nurse would point out that the growing fetus is getting nutrition from the mother via which structure?
Umbilical arteries.
Placenta.
Amniotic fluid.
Decidua.
The Correct Answer is B
“Placenta.” The placenta is the structure that provides oxygen and nutrients to the growing fetus and removes waste products from the fetus’s blood.
Choice A is incorrect because the umbilical arteries carry deoxygenated blood and waste products from the fetus to the placenta.
Choice C is incorrect because amniotic fluid provides a cushion for the fetus and helps maintain a constant temperature in the uterus but does not provide nutrition.
Choice D is incorrect because the decidua is the lining of the uterus during pregnancy and does not provide nutrition to the fetus.
