Her only problem was that with each pregnancy she gained 50 lbs (23 kg) and had difficulty losing the weight afterward. She has no complaints today. Looking at her chart, you see she is currently 10 weeks pregnant and that her prenatal weight was 130 lbs (59 kg) . Her weight today is 134 lbs (60.9 kg) . Her height is 5'4", giving her a BMI of 22. Her blood pressure, pulse, and urine tests are unremarkable. The fetal heart tone is difficult to find but is located and is 150. While you give her first trimester education, you tell her how much weight you expect her to gain. How much weight should this patient gain during pregnancy?
