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 C

Explanation

Choice A rationale

Chromosomal defects are typically assessed using different tests, such as chorionic villus sampling or amniocentesis, rather than an ultrasound at this early stage.

Choice B rationale

Fetal lung maturity cannot be assessed at 9 weeks gestation because the lungs are not yet developed. This assessment is usually done later in pregnancy if preterm delivery is anticipated.

Choice C rationale

At 9 weeks gestation, the primary purpose of an ultrasound is to confirm the presence of a fetal heartbeat, which indicates a viable pregnancy.

Choice D rationale

The position of the fetus in utero is not a concern at this early stage of pregnancy. Fetal positioning becomes relevant later in pregnancy, closer to delivery.
