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.

Answer and Explanation

The Correct Answer is A

Choice A rationale
Inadequate weight gain during pregnancy can lead to intrauterine growth restriction (IUGR), where the fetus does not grow as expected.
Choice B rationale
Excess weight gain is not solely due to overeating; it can result from edema, gestational diabetes, or other metabolic factors.
Choice C rationale
Height is a factor in determining a pregnant woman’s target weight range, influencing the overall recommended weight gain.
Choice D rationale
Obese women have higher risks of complications, including gestational diabetes and hypertensive disorders, differing from normal weight women.

Correct Answer is B

Explanation

Choice A rationale
Although the placenta acts as a partial barrier, it does not keep out all harmful substances, allowing some to cross and affect fetal development.
Choice B rationale
One of the placenta's early functions is producing hormones like human chorionic gonadotropin (hCG), estrogen, and progesterone, making it act as an endocrine gland.
Choice C rationale
The placenta does not thin out; it remains robust and increases in thickness to support the growing fetus and facilitate nutrient and gas exchange.
Choice D rationale
While optimal blood circulation through the placenta is crucial, this statement lacks detail on the specific structural and functional aspects of the placenta.

A. Metal detectors at airport security checkpoints can harm the fetus if the woman passes through them a number of times. B. Women should avoid seat belts and shoulder restraints in the car because they press on the fetus. C. While working or traveling in a car or on a plane, women should arrange to walk around at least every hour or so. D. Women should sit for as long as possible and cross their legs at the knees from time to time for exercise.

Correct Answer is C

Explanation

Choice A rationale
Metal detectors at airport security checkpoints are considered safe and do not pose any risk of harm to the fetus.
Choice B rationale
Seat belts and shoulder restraints should always be used as they provide essential protection for both the mother and the fetus during travel.
Choice C rationale
Pregnant women are advised to walk around every hour during long periods of sitting to improve circulation and prevent blood clots, enhancing fetal health.
Choice D rationale
Prolonged sitting and crossing legs can impede circulation and increase the risk of venous thromboembolism, making it essential to avoid such practices.
