A nurse is reinforcing nutrition teaching with a client during the first prenatal visit. Which of the following statements by the client indicates understanding of the teaching?

Choice A:
Purpose of the Biophysical Profile (BPP): The BPP is a non-invasive test that combines ultrasound and fetal heart rate monitoring to assess fetal well-being, specifically in the third trimester of pregnancy. It evaluates five parameters: fetal breathing movements, fetal body movements, fetal tone, amniotic fluid volume, and fetal heart rate reactivity. Each parameter is assigned a score of 0 or 2, resulting in a total score of 0 to 10. A score of 8 or 10 is generally considered reassuring of fetal well-being, while a score of 6 or below may warrant further evaluation or intervention.
Timing of BPP: It's typically performed in the third trimester, often after 32 weeks of gestation, when the fetus has developed regular sleep-wake cycles and breathing movements.
Risk Assessment: It's often recommended for pregnancies considered high-risk, such as those with: Maternal diabetes
Preeclampsia
Decreased fetal movement Past stillbirth
Multiple gestation
Oligohydramnios (low amniotic fluid) Post-term pregnancy (over 42 weeks)

Choice B:
IV initiation is not a routine part of BPP: Intravenous (IV) access is not typically required for a BPP. The test involves external monitoring of fetal heart rate and ultrasound imaging, which do not necessitate IV access.

Choice C:
NPO status is not necessary: The client does not need to be NPO (nothing by mouth) for a BPP. There are no dietary restrictions or fasting requirements for this test.

Choice D:
BPP does not determine the estimated date of birth: The primary purpose of the BPP is to assess fetal well-being, not to determine the estimated date of delivery (EDD). The EDD is typically established based on the last menstrual period or early ultrasound measurements.

The correct answer is Choice A.

Choice A rationale: The recommended weight gain for a woman with a normal BMI (18.5-24.9) during pregnancy is 25-35 pounds. This range ensures adequate nutrition for both the mother and the developing baby, supporting optimal fetal growth and maternal health.

Choice B rationale: A weight gain of 11-20 pounds is recommended for women with a high BMI (≥30) during pregnancy. This range helps minimize the risk of complications such as gestational diabetes and hypertension, but it is not applicable for a woman with a normal BMI.

Choice C rationale: While a healthy diet is crucial, specific weight gain guidelines are essential to ensure the health of both mother and baby. Weight gain recommendations are based on evidence to support optimal outcomes, making it important to follow them.

Choice D rationale: A weight gain of 15-25 pounds is recommended for women with an overweight BMI (25-29.9) during pregnancy. This range helps support fetal growth while minimizing the risk of complications, but it is not applicable for a woman with a normal BMI.
