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?

A. "The recommendation for you is about 15 to 25 pounds." This recommendation is appropriate for clients who are overweight (BMI 25–29.9), not those with a normal BMI. B. "A gain of about 25 to 35 pounds is recommended for you." A BMI of 23.5 falls within the normal range (18.5–24.9). The recommended total weight gain for clients with a normal BMI is 25–35 lbs (11.3–15.9 kg) during pregnancy to support fetal growth and maternal health. C. "A gain of about 1 pound per week is the best pattern for you." While the recommended weight gain in the second and third trimesters is about 1 lb/week, total weight gain is individualized based on pre-pregnancy BMI. D. "It would be best if you gained about 11 to 20 pounds." This is the recommendation for obese clients (BMI ≥30), not those with a normal BMI.
