What You Should Be Able to Do
Use the measured height and the pre pregnancy, or earliest available first trimester, weight to assign the correct BMI category.
Use the measured height and the pre-pregnancy, or earliest available first-trimester, weight to assign the correct BMI category. Apply the singleton and provisional twin-pregnancy targets without treating them as rigid pass–fail thresholds. Interpret first-trimester gain separately from the later-pregnancy rate. Distinguish expected physiologic fluid and tissue expansion from a concerning trend, and distinguish a weight-related prompt to assess from evidence that actually establishes preeclampsia. Counsel about nutrition, activity, supplementation, and avoidance of intentional weight loss. Recognize how obesity changes fetal surveillance, labour planning, and postpartum follow-up.
