Select one:

Second and third trimesters insulin needs increase because the placenta is fully developed.

Maternal insulin requirements are never modified during pregnancies.

Answer and Explanation

The Correct Answer is A

a.   As the placenta grows and becomes more metabolically active, it produces hormones that increase insulin resistance, leading to an increased need for insulin.
b.   Women with insulin-dependent diabetes may be prone to hyperglycemia during pregnancy, but it is not due to consuming more simple sugar.
c.   Maternal insulin requirements often increase during pregnancy due to increased insulin resistance.

d.   Insulin crosses the placenta throughout pregnancy, and the fetus does not secrete its own insulin until after birth.
