A 16-year-old client at 18 weeks gestation with a normal BMI expresses concern about weight gain during pregnancy. The client wants to know how to avoid gaining too much weight. What is an appropriate response from the nurse?

A high-protein, low-carbohydrate diet may help keep your weight gain under control.

You are eating for two now, but breastfeeding can help you lose excess weight later.

Gaining 1 lb (0.5 kg) per week in this stage of pregnancy is important and expected.

You can exercise daily, so you don’t have to worry about weight gain.

Answer and Explanation

The Correct Answer is C

Choice A rationale

High-protein, low-carbohydrate diets are not recommended during pregnancy as they can lead to ketone production, which may harm fetal development. A balanced diet is crucial for maternal and fetal health.

Choice B rationale

Although breastfeeding can help with postpartum weight loss, it is not advisable to use pregnancy as a reason to overeat. Healthy weight gain during pregnancy is essential for fetal development.

Choice C rationale

Gaining 1 lb (0.5 kg) per week is recommended during the second trimester for a client with a normal BMI to ensure proper fetal growth and development.

Choice D rationale

Exercise is beneficial, but it cannot prevent all weight gain during pregnancy. Appropriate weight gain is necessary for fetal health and development.

Correct Answer is D

Explanation

Choice A rationale

The ductus arteriosus does not connect the umbilical artery to the inferior vena cava. It connects the pulmonary artery to the aorta, bypassing the lungs in fetal circulation.

Choice B rationale

The ductus arteriosus carries deoxygenated blood from the right side of the heart to the aorta. It does not carry oxygenated blood from the left side of the heart.

Choice C rationale

The ductus arteriosus is not located between the right and left atrium. It is a blood vessel connecting the pulmonary artery to the aorta in fetal circulation.

Choice D rationale

In fetal circulation, the pulmonary artery and aorta are connected via the ductus arteriosus. This allows blood to bypass the fetal lungs, which are not yet functional.

NGN QUESTIONS

A. Ultrasonography. B. Human chorionic gonadotropin (HCG) levels. C. Nagele’s rule. D. Fundal height.

Correct Answer is A

Explanation

Choice A rationale

Ultrasonography provides the most accurate assessment of gestational age, especially in the first trimester, by measuring the crown-rump length.

Choice B rationale

HCG levels can indicate pregnancy but are not as accurate for determining the exact gestational age.

Choice C rationale

Nagele's rule is based on the menstrual cycle and may not be accurate if cycles are irregular.

Choice D rationale

Fundal height measurement is less accurate in early pregnancy and more useful in later trimesters.
