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 A

Explanation

Choice A rationale

Intrauterine growth restriction (IUGR) is a significant risk for newborns of mothers who smoke. Smoking affects placental blood flow, reducing the supply of oxygen and nutrients to the fetus, leading to poor growth.

Choice B rationale

Smoking is not a direct cause of gestational diabetes. Gestational diabetes is primarily related to hormonal changes in pregnancy that affect insulin regulation.

Choice C rationale

Congenital heart defects are not directly linked to smoking. They are usually caused by genetic and environmental factors during early fetal development, not smoking specifically.

Choice D rationale

Vision loss is not directly associated with maternal smoking. Smoking affects fetal growth and development, but vision loss is not a common outcome.
