A nurse is caring for a client at the first prenatal visit who has a BMI of 23.5. The client asks how much weight she should gain during pregnancy.Which of the following responses should the nurse make?

Choice A rationaleA pre-pregnancy BMI of 23.5 falls within the normal weight range (18.5 to 24.9 kg/m²). For individuals with a normal pre-pregnancy BMI, the recommended total weight gain during pregnancy is 25 to 35 pounds (11.3 to 15.9 kg). This range supports optimal fetal growth without significantly increasing the risk of maternal or fetal complications associated with excessive weight gain.Choice B rationaleWhile a gradual weight gain is generally recommended, stating "about 1 pound per week" is an oversimplification and doesn't account for the varying rates of weight gain throughout pregnancy. The rate of weight gain is typically lower in the first trimester and higher in the second and third trimesters. Focusing solely on a weekly gain might cause unnecessary anxiety if the client's weight gain fluctuates slightly.Choice C rationaleA recommended weight gain of 15 to 25 pounds is appropriate for individuals with an overweight pre-pregnancy BMI (25 to 29.9 kg/m²), not a normal BMI. Recommending this lower range to a client with a normal BMI could lead to inadequate weight gain and potentially compromise fetal development due to insufficient nutrient supply.Choice D rationaleA recommended weight gain of 11 to 20 pounds is typically advised for individuals with an obese pre-pregnancy BMI (30 kg/m² or higher). Suggesting this lower range to a client with a normal BMI could restrict necessary weight gain for a healthy pregnancy and fetal growth.
