Which statement shows the client understands approximately how many calories per day she needs over her normal pre-pregnant needs?

Choice A rationale This statement is incorrect as caloric needs increase during pregnancy to support fetal growth, placental development, and increased maternal metabolic demands. Inadequate caloric intake can lead to poor fetal outcomes, including low birth weight and impaired development. Choice B rationale While caloric needs do increase, an additional 500 calories is generally too high for the average pregnancy. The recommended increase is typically lower, focusing on nutrient-dense foods to ensure sufficient energy for both mother and fetus. Choice C rationale Doubling caloric intake is excessive and can lead to excessive maternal weight gain, increasing risks for gestational diabetes, preeclampsia, and delivery complications. The concept of "eating for two" is a common misconception that often leads to overconsumption. Choice D rationale During the second and third trimesters, the average pregnant woman requires an additional 300 calories per day above her pre-pregnancy needs. This increase provides adequate energy for rapid fetal growth, development, and maternal physiological changes, such as increased blood volume and uterine expansion.
