    About the Lecture

    The lecture Routine Care: Establishing Gestational Age with Ultrasound by Veronica Gillispie, MD, FACOG is from the course Antenatal Care.


    Included Quiz Questions

    1. The gestational age calculated by transvaginal ultrasound should be used to calculate the estimated due date.
    2. The gestational age based off her last menstrual period should be used to calculate the estimated due date.
    3. An average gestational age should be calculated based off her last menstrual period and the transvaginal ultrasound.
    4. Neither gestational age should be used. A more accurate dating scan should be done in the second trimester.
    5. A repeat transvaginal ultrasound must be done later in the first trimester to determine an accurate gestational age.
    1. Second trimester ultrasounds are most accurate for establishing gestational age.
    2. First trimester ultrasounds can estimate the gestational age within one week of accuracy.
    3. Second trimester ultrasounds can estimate the gestational age within two weeks of accuracy.
    4. Third trimester ultrasounds can estimate the gestational age within threes weeks of accuracy.
    5. If a first trimester ultrasound measures a gestational age within one week of the last menstrual period, the last menstrual period should be used to establish the gestational age.
    1. 8 weeks 0 days
