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

A. "A gain of about 1 pound per week is recommended for you.": Although gaining approximately 1 pound per week during the second and third trimesters is typical, this does not address the total recommended weight gain. A more complete answer should reflect the full pregnancy range. B. "A gain of about 15 to 25 pounds is recommended for you.": This weight gain range is appropriate for someone who is overweight before pregnancy. For individuals with an ideal pre-pregnancy weight, a higher range is recommended to support fetal growth and maternal health. C. "A gain of about 25 to 35 pounds is recommended for you.": This is the recommended total weight gain for a client who starts pregnancy at an ideal body weight. It supports healthy fetal development, amniotic fluid volume, placental growth, and maternal tissue changes. D. "A gain of about 30 to 40 pounds is recommended for you.": This range is more appropriate for underweight clients, who need additional weight to support pregnancy needs. For someone with an ideal weight, it exceeds what is generally advised.
