Correct Answer is C
Explanation
Choice A rationale
The placenta does not cushion the fetus from maternal movement. Instead, the amniotic fluid within the amniotic sac provides cushioning and protection to the fetus from external forces and maternal movements.
Choice B rationale
The placenta does not provide thermoregulation. Thermoregulation is primarily managed by the mother’s body. The placenta’s main functions are related to nutrient and gas exchange, hormone production, and waste removal.
Choice C rationale
The placenta is responsible for metabolic and gas exchange. It provides oxygen and nutrients to the fetus while removing waste products from the fetal blood. This exchange occurs through the placental barrier, which separates maternal and fetal blood.
Choice D rationale
The placenta does not provide a sterile environment. The amniotic sac and its fluid help maintain a sterile environment for the fetus. The placenta’s role is more focused on nutrient and gas exchange, hormone production, and waste removal.
Correct Answer is C
Explanation
Choice A rationale
The recommended limit for caffeine intake during pregnancy is generally 200 mg or less per day. Consuming 400 mg of caffeine daily exceeds this recommendation and may increase the risk of adverse pregnancy outcomes.
Choice B rationale
It is recommended to avoid alcohol entirely during pregnancy, as even small amounts can increase the risk of fetal alcohol spectrum disorders and other complications. Therefore, having one alcoholic beverage a week is not considered safe.
Choice C rationale
Drinking at least 8-10 cups of fluid each day is a good practice during pregnancy to maintain adequate hydration, support increased blood volume, and promote overall health. This statement indicates that the client understood the education provided.
Choice D rationale
Pregnant individuals should not decrease their intake of essential nutrients like calcium, magnesium, iron, and vitamin D. These nutrients are important for fetal development and maternal health. Instead, they should ensure they are getting adequate amounts through diet and supplements as recommended by their healthcare provider.
