A 26-year-old woman, gravida 2, para 1, presents with a positive pregnancy test.

Accurate dating is critical in pregnancies at high risk for preeclampsia and intrauterine growth restriction. First-trimester ultrasound is used to establish gestational age, which guides monitoring and interventions.

Toronto Notes 2023 – Obstetrics, High-Risk Pregnancy:

“In women with a history of preeclampsia, early and accurate dating allows for appropriate fetal surveillance and timely delivery.”

MCCQE1 Objectives – Obstetrics > Prenatal Care:

“Candidates should recognize the importance of accurate pregnancy dating in high-risk pregnancies.”

Prophylactic labetalol (E) is not indicated in normotensive patients. Genetic testing (A, B) is not appropriate unless additional risk factors are present. Bed rest (D) is not evidence-based for preeclampsia prevention.
