|
Amniotic fluid
|
|
|
Function of amniotic fluid
|
Cushioning, maintain contant body temperature of fetus
|
|
|
Rebounding of the fetus against the examiner's finger on palpation. When the examiner taps the cervix, the fetus floats upward in the amniotic fluid. The examiner feels a rebound when the fetus falls back.
|
Ballottment

|
Actual event of birth; the expulsion or extraction of the neonate
|
Delivery
|
|
|
Stage of fetal development that lasts from day 15 until approximately 8 weeks after conception or until the embryo measures 3 cm from crown to rump
|
Embryo
|
|
|
Uniting of the sperm and ovum, which occurs within 12 hours of ovulation and within 2-3 days of insemination, the average duration of viability for the ovum and sperm

Fertilization
|
|
|
Softening of the cervix that occurs at the beginning of the second month of gestation and is a probable sign of pregnancy
|
Goodell's sign
|

Hegar's sign
|
|
|
Attachment of the zygote to the uterine wall 6-10 days after conception
|
Implantation
|
|
|
Coordinated sequence of involuntary uterine contractions resulting in effacement and dilation of cervix, followed by expulsion of the fetus/neonate
|
labor
|
|
|
the ratio of two components of amniotic fluid, used for predicting fetal lung maturity
|
Lecithin (L)-to-Sphingomyelin (S) ratio
L/S Ratio |
|
|
Normal L/S ratio in amniotic fluid
|
2:1 or higher indicates fetal lung maturity
|
|
|
discharge from the uterus that consists of blood from the vessels of the placental site and debris from the decidua
|
lochia
|
|
|
how long does lochia last following delivery
|
2-3 weeks
|
|
|
determines the estimated date of confinement and works on the premise that the woman has a 28-day menstrual cycle.
|
Nagele's Rule

|
|
The number of pregnancies that have been carried to viability
|

|
|
first perception of fetal movement, appearing usually in the 16-20th week of pregnancy
|
Quickening
