2027 Updated.
G/P - Answer Gravida(pregnancies)/Parity (births past 22 weeks)
G/P/A/L - Answer Gravida/Parity/Abortion/Live
G/T/P/A/L - Answer G = Gravida (pregnancies)
T = Term (38-42 wk)
P = Preterm (20-37 wk)
A = abortion (spontaneous or induced)
L = # of living children
Terbutaline - Answer Adrenergic bronchodilator
usually asthma med
*prevents and slows contraction of uterus*
Betamethasone - Answer Corticosteroid
increases surfactant production and lung maturity in preterm babies
Progesterone - Answer Released to maintain pregnancy w/fertilized egg
Decreased to induce menses w/unfertilized egg
hCG (human chorionic gonadotropin) - Answer confirms pregnancy
8-10 after conception is detectable
hCS/hPL - Answer increases available glucose for fetus and prepares breasts for lactation, acts

Why are women more prone to yeast infection? - Answer change in vaginal pH
Colostrum production starts at - Answer 16 weeks gestation
Preeclampsia, HELLP syndrome and gestation HTN increase risk of - Answer DVT, blood clots
These conditions decrease # of blood platelets, which causes body to respond by increasing
clotting factors to compensate
Preeclampsia - Answer hypertension, edema, and proteinuria during pregnancy
How to calculate due date? - Answer 1. ultrasound
2. Naegele's rule: based on accurate recall of LMP; assumes pt. has 28 day cycle
*subtract 3 months from first day of LMP and add 7 days to next year.
