Prevents the fetal skin from drying out
Allows for symmetrical growth of the fetus
Helps maintain an even temperature
Separates the maternal and fetal blood
Correct Answer : A,B,C
A. Prevents the fetal skin from drying out is correct. Amniotic fluid plays a protective role by keeping the fetal skin moist, preventing it from drying out.
B. Allows for symmetrical growth of the fetus is correct. Amniotic fluid helps ensure that the fetus has adequate room to grow and develop symmetrically, preventing physical restrictions.
C. Helps maintain an even temperature is correct. Amniotic fluid helps regulate the temperature around the fetus, protecting it from fluctuations in the external environment.
D. Separates the maternal and fetal blood is incorrect. Amniotic fluid does not separate maternal and fetal blood. This function is carried out by the placenta, which serves as a barrier between maternal and fetal blood.

Correct Answer is A
Explanation
A. The maternal-fetal circulation is established by 12 weeks of gestation, allowing oxygen and nutrients to be exchanged between the mother and fetus through the placenta.
B. Lanugo begins developing around 20 weeks and starts to disappear closer to week 36, rather than covering the entire body at that time.
C. Fetal movement (quickening) is usually felt between 16-20 weeks, not as late as 24 weeks.
D. The sex of the baby is determined at conception, but external genitalia do not fully differentiate until around 12-14 weeks, not at 8 weeks.
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.
