    breech presentation
    when the fetal buttocks (or legs) present into the pelvis first
    cephalic presentation
    when the fetal head presents into the pelvis first
    cervical ripening
    softening and opening of the cervix as it prepares for labor
    clinical pelvimetry
    assessment of the general shape and size of the patient’s pelvis
    consanguinity
    shared ancestry, such as when the parents are first cousins
    estimated date of delivery (EDD)
    date the pregnant patient is expected to give birth, plus or minus 2 weeks
    fetal lie
    relationship of the fetal spine to the pregnant patient’s spine
    fetal presentation
    part of the fetus entering the pregnant patient’s pelvis first
    first trimester
    0 to 13 weeks and 6 days of gestation
    fundal height
    measurement from the symphysis pubis to where the fundus (or top) of the uterus is palpated in a patient who is pregnant
    gravidity
    total number of times the patient has been pregnant (including the current pregnancy) regardless of the outcome or number of fetuses
    integrated or sequential screenings
    tests performed in the first and second trimesters of pregnancy to determine if there is an increased risk for abnormal chromosome and neural tube defects in the fetus
    Leopold’s maneuvers
    a specific method of palpating the pregnant patient’s abdomen to determine the fetal lie, fetal presentation, location of the fetal back, and, with deeper palpation, the fetal position; can also be used, along with measurement of the fundal height, to estimate the fetal weight
    longitudinal lie
    when the fetal spine lines up vertically with the pregnant patient’s spine
    multiparous
    pregnant person who has given birth one or more times after 20 weeks of gestation
    Naegele’s Rule
    three-step calculation based on a 28-day menstrual cycle, used to determine a pregnant patient’s due date: subtract 3 months from the first day of the last menstrual period (LMP); add 7 days to the LMP; and adjust the year as needed
    oblique lie
    when the fetal spine lies on the diagonal of the pregnant patient’s spine
    parity
    number of pregnancies where the patient has reached 20 weeks of gestation or more regardless of whether the pregnancy ended in a live birth or stillbirth
    primiparous
    person who is pregnant for the first time
    quad marker screen
    measures the maternal serum levels of four pregnancy markers, alpha fetoprotein, hCG, unconjugated estriol, and inhibin-A, to determine if there is an increased risk for abnormal chromosome and neural tube defects in the fetus and is performed at 15 to 20 weeks of pregnancy
    second trimester
    14 to 27 weeks and 6 days of gestation
    shoulder presentation
    when the fetus is in a transverse lie and the shoulder is presenting into the pelvis first
    third trimester
    week 28 until delivery (usually by 42 weeks’ gestation)
    transverse lie
    when the fetal spine lines up horizontally with the pregnant patient’s spine, like the plus (+) sign
    trimester
    14 weeks of pregnancy; the 280 days of gestation during pregnancy are divided into three periods, called trimesters
