A nurse is caring for an adolescent client who is at 24 weeks of gestation. The client's prepregnancy weight was within the recommended range for their height and they have gained 2.7 kg (6 lb) during the pregnancy. Which of the following statements should the nurse make?

Choice A rationale While weight gain is crucial during pregnancy, a blanket statement of 2 pounds per week is not universally appropriate. The recommended rate of weight gain varies based on the client's pre-pregnancy BMI and the trimester. Excessive or insufficient weight gain can lead to adverse maternal and fetal outcomes, including macrosomia or intrauterine growth restriction, highlighting the need for individualized nutritional guidance rather than a fixed weekly gain. Choice B rationale Dieting during pregnancy, especially restrictive calorie intake, can significantly compromise the nutrient supply to the developing fetus. Fetal growth and organogenesis are highly dependent on adequate maternal nutritional stores and daily nutrient intake. Inadequate nutrition can lead to low birth weight, premature birth, and long-term health complications for the infant, emphasizing the dangers of unguided dietary restrictions. Choice C rationale A dietitian possesses specialized knowledge in medical nutrition therapy and can provide personalized recommendations based on the adolescent's specific nutritional needs, gestational age, and pre-pregnancy weight. This collaborative approach ensures optimal maternal and fetal health by addressing any deficiencies, managing appropriate weight gain, and promoting healthy eating habits throughout the pregnancy, which is crucial for adolescent development and pregnancy outcomes. Choice D rationale The caloric needs of a pregnant adolescent increase in the second and third trimesters, but a fixed additional 700 calories per day may not be accurate for all individuals. Caloric requirements are dynamic and depend on pre-pregnancy weight, activity level, and the specific stage of gestation. Overestimation can lead to excessive weight gain, while underestimation can result in inadequate fetal growth, necessitating individualized assessment.
