Correct Answer is ["A","B","C"]

Explanation

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. Deepening pigmentation, such as changes in the skin like melasma or linea nigra, is considered a presumptive sign of pregnancy, as it is subjective and not specific to pregnancy alone.

B. Abdominal enlargement is a probable sign of pregnancy as it is more objective and can be caused by the growing uterus. However, it may also occur due to other conditions, such as tumors or fluid accumulation.

C. Ballottement, a sensation felt when the fetus rebounds after being pushed gently, is a probable sign of pregnancy due to its reliance on the presence of a fetus.

D. A positive pregnancy test result is a probable sign because it detects hCG levels, which are strongly associated with pregnancy but may also be elevated in other conditions.
