What is parity?

Give the GxPx description of a woman who is currently pregnant and had a previous pregnancy that did not survive beyond 10 weeks
G2P0
A woman who has never carried a pregnancy beyond 20 weeks
nulliparous
A woman who has never been pregnant
nulligravida
A woman in her first pregnancy
primigravida
A woman with multiple pregnancies
multigravida
A woman who has had four or more 20+ week pregnancies
grand multipara
The parity does not take into account multiple gestations (e.g. twins).
T/F
True.
Describe the GTPAL system of terminology.
- Gravidity – total # of pregnancies
- Term – total # of infants born at term (at or after 37 weeks)
- Preterm – total # born before 37 weeks and after 24 weeks
- Abortions – total # of spontaneous or induced abortions from impregnation to 24 weeks
- Living – total # of children currently living
Using the GTPAL system, how would you chart a woman who has been pregnant one time with twins who were delivered at 35 weeks of gestation and survived?
What would be the abbreviation during her next pregnancy?
Now: G1T0P2A0L2
Next pregnancy: G2T0P2A0L2

When will the gestational sac be visible on ultrasound?
4-5 weeks
When should fetal heart beat be detectable by ultrasound?
6 weeks
Describe Naegele’s rule for determination of Estimated Due Date.
Subtract 3 months from the first day of the LMP, add 7 days and one year.
Example: LMP started 7/16/13
Subtract 3 months - 4/16/13
Add 7 days and one year - 4/23/14
When can fetal heart tones be heard using Doppler?
