With regard to weight gain during pregnancy, the nurse should be aware of which important information?

Women with inadequate weight gain have an increased risk of delivering an infant with intrauterine growth restriction (IUGR).

Greater than expected weight gain during pregnancy is almost always attributable to old-fashioned overeating.

In pregnancy, the woman’s height is not a factor in determining her target weight.

Obese women may have health concerns, but the risk of delivering a child with major congenital defects is the same as with women of normal weight.
