In fetal circulation, the ductus venosus diverts blood from which of the following organs?

Lungs

Heart

Kidney

Liver

Answer and Explanation

The Correct Answer is D

A. The lungs are bypassed by the foramen ovale and ductus arteriosus in fetal circulation, not the ductus venosus.

B. The heart is a critical pumping organ, so no blood is diverted away from it in fetal circulation.

C. The kidneys process blood, but fetal blood bypasses the liver via the ductus venosus rather than the kidneys.

D. The ductus venosus allows oxygen-rich blood from the umbilical vein to bypass the liver and flow directly into the inferior vena cava, ensuring that well-oxygenated blood reaches vital fetal organs, such as the brain and heart, more efficiently.

Correct Answer is D

Explanation

A. A ketogenic diet is not recommended during pregnancy, as carbohydrates are essential for fetal growth and energy. Adequate, balanced nutrition is key during pregnancy.

B. While water intake is important, pregnant clients are advised to drink 8–10 glasses of water daily to support increased blood volume and amniotic fluid. Six glasses would be insufficient.

C. An additional 1,000 calories per day is excessive for early pregnancy. During the first trimester, the calorie increase is minimal (approximately 150–200 calories), with more significant increases later in pregnancy.

D. Taking a prenatal vitamin daily ensures adequate intake of essential nutrients like folic acid and iron, which are critical for preventing neural tube defects and supporting maternal health.

A. Your partner's condition should not affect any future children B. We can test you, but not your partner, for any conditions that might complicate a pregnancy C. We can offer you and your partner testing to identify the chance of passing genetic conditions to your children D. This type of testing is not done until there is a confirmed pregnancy

Correct Answer is C

Explanation

A. This response dismisses the client's concern and is not accurate since a partner’s genetic condition can affect offspring depending on inheritance patterns.

B. Testing only one partner is not sufficient to assess the risk of passing on hereditary conditions since the genetic contribution of both parents matters.

C. Offering genetic testing to both partners is the correct response as it enables the identification of hereditary risks and provides information about the likelihood of passing on genetic disorders to their children. This approach is aligned with patient-centered care.

D. Genetic testing does not require a confirmed pregnancy. Preconception genetic counseling and testing are commonly offered to assess potential risks beforehand.
