Final answer:
The 27-year-old who gained 23 pounds during her pregnancy is the one who met the goal for a healthy weight gain, as this aligns with the recommended 25 to 35 pounds total weight gain for individuals of a normal initial weight. The woman who met the goal for a healthy weight gain in pregnancy is option d, the 27-year-old who gained 23 pounds.
Explanation:
To determine which woman met the goal for a healthy weight gain in pregnancy, let's analyze the weight gain guidelines. During the first trimester, there is an expected weight gain of approximately 1 lb per month. From the second trimester onwards, the average weight gain is about 1 lb per week due to an increased intake of 300 calories per day. Now, let's evaluate each option based on these guidelines:
- a. Gained 4 pounds - Given her initial weight, a healthy weight gain should be around 25 to 35 pounds for the entire pregnancy. Her gain is too low for a healthy pregnancy.
- b. Gained 15 pounds - Considering her initial high weight, her pregnancy weight gain should be on the lower end, but this still seems excessive and above the recommended gain for overweight individuals.
- c. Gained 47 pounds - This is significantly above the recommended weight gain, indicating an unhealthy pregnancy weight gain.
- d. Gained 23 pounds - This aligns more closely with the recommended weight gain of approximately 25 to 35 pounds for the entire pregnancy for someone of a normal initial weight, making it the healthiest weight gain among the options.
Therefore, the woman who met the goal for a healthy weight gain in pregnancy is option d, the 27-year-old who gained 23 pounds.
