Final answer:
A pregnant woman with a BMI of 34 should maintain her current BMI during her pregnancy. Weight gain of approximately 0.45 kg (1 lb) per month is common in the first trimester, with an additional 0.45 kg (1 lb) per week in the second and third trimesters. The mother should consume an additional 300 calories per day to support the growing fetus.
Step-by-step explanation:
During pregnancy, it is important for a woman to maintain a healthy weight. For a client with a BMI of 34 at 8 weeks gestation, the nurse should advise her to maintain her current BMI. During the first trimester, the mother does not need to consume additional calories to maintain a healthy pregnancy. A weight gain of approximately 0.45 kg (1 lb) per month is common. In the second and third trimesters, an additional 300 calories per day are needed, and most women gain approximately 0.45 kg (1 lb) per week.
