Fetal nutrition and excretion are carried out by the placenta.

Fetal respirations are carried out by the placenta.

The placenta filters harmful substances from maternal blood.

The placenta receives maternal blood from the uterine arteries.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Fetal nutrition and excretion are carried out by the placenta. This statement is correct. The placenta provides essential nutrients to the fetus and removes waste products from fetal blood.

Choice B rationale

Fetal respirations are carried out by the placenta. This statement is correct. The placenta facilitates gas exchange, providing oxygen to the fetus and removing carbon dioxide.

Choice C rationale

The placenta filters harmful substances from maternal blood. This statement is incorrect. While the placenta provides some barrier function, it does not filter all harmful substances from maternal blood, and certain drugs and toxins can cross the placental barrier and affect the fetus.

Choice D rationale

The placenta receives maternal blood from the uterine arteries. This statement is correct. Maternal blood flows to the placenta via the uterine arteries, supplying oxygen and nutrients to the fetal side of the placenta.

Correct Answer is B

Explanation

Choice A rationale

Maintaining a folic acid intake of 4 mcg per day is not sufficient. The recommended dose for pregnant women is 400-800 mcg to help prevent neural tube defects, but it is not specifically related to reducing the risk of preterm labor.

Choice B rationale

Increasing fluid intake to 8-10 (8 oz) glasses per day is recommended as it helps to maintain hydration, which is crucial in preventing preterm labor. Dehydration can cause uterine contractions, which can lead to preterm labor.

Choice C rationale

Consuming the recommended daily allowance of vitamin C (85 mg) is important for immune function and overall health but does not directly affect the risk of preterm labor.

Choice D rationale

Increasing caloric intake by 500 calories per day is typically recommended for breastfeeding mothers, not for preventing preterm labor during pregnancy. Proper nutrition is important, but overconsumption can lead to excessive weight gain.
