Pale, straw-colored fluid in which the fetus floats. It serves as a cushion against injury from sudden blows or movements and helps maintain a constant body temperature for the fetus. The fetus modifies the amniotic fluid through the processes of swallowing, urinating, and movement through the respiratory tract.
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.
Violet coloration of the mucous membranes of the cervix, vagina, and vulva that occurs at about 4 weeks of pregnancy caused by increased vascularity. This is considered a probable sign of pregnancy.
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.
Uniting of the sperm and ovum, which occurs within 12 hours of ovulation and within 2 to 3 days of insemination, the average duration of viability for the ovum and sperm.
Softening of the cervix that occurs at the beginning of the second month of gestation. This is considered a probable sign of pregnancy.
A pregnant woman; called gravida I (primigravida) during the first pregnancy, gravida II during the second pregnancy, and so on.
Compressibility and softening of the lower uterine segment that occurs at about week 6 of gestation. This is considered a probable sign of pregnancy.
Coordinated sequence of rhythmic involuntary uterine contractions resulting in effacement and dilation of the cervix, followed by expulsion of the products of conception.
lecithin-to-sphingomyelin (L/S) ratio
Ratio of two components of amniotic fluid, used for predicting fetal lung maturity; normal L/S ratio in amniotic fluid is 2:1 or greater when the fetal lungs are mature.
Discharge from the uterus that consists of blood from the vessels of the placental site and debris from the decidua; lasts for 2 to 6 weeks after delivery.
Determines the estimated date of birth based on the premise that the woman has a 28-day menstrual cycle. Add 7 days to the first day of the last menstrual period; subtract 3 months and add 1 year. Alternatively, add 7 days to the last menstrual period and count forward 9 months.
Number of pregnancies that have reached viability regardless of whether the fetus was born alive or stillborn.
Organ that provides for the exchange of nutrients and waste products between the fetus and the mother and produces hormones to maintain pregnancy. The placenta develops by the third month of gestation and is also called afterbirth.
Maternal perception of fetal movement for the first time, occurring usually in the sixteenth to twentieth week of pregnancy.
Phospholipid that is necessary to keep the fetal lung alveoli from collapsing; amount is usually sufficient after 32 weeks' gestation.
Organ located behind the symphysis pubis, between the bladder and the rectum. It has four parts—fundus (upper part), corpus (body), isthmus (lower segment), and cervix.
Tubular structure located behind the bladder and in front of the rectum; it extends from the cervix to the vaginal opening in the perineum. It functions as the outflow tract for menstrual fluid and for vaginal and cervical secretions, the birth canal, and the organ for coitus.
Capability of the fetus to survive outside the uterus; about 22 to 24 weeks of gestation or fetal weight more than 500 g.
slight abnormal deviation from delivery trauma. it is capillary bleeding between the periosteum and skull. often caused by FORCEPS
connect umbilical vein with inferior vena cava, passes through/largely bypasses the liver.
a glucocorticoid given (after after mag sulfate for preterm labor) to increase surfactant producation to stimulate fetal lung maturation. given at 28 to 32 wks if mag is successful in inhibiting labor for 48 hrs.
food rich in Iron:
LEGUMES, meat, liver, whole grain breads, deep green leafy veggies, dried fruits.
In first-time pregnancies the uterus sinks downward and forward about 2 weeks before term, when the fetus's presenting part (usually the fetal head) descends into the true pelvis. also called dropping
third trimester painless bleeding
characteristic of placenta previa and diagnosed by transabdominal ultrasound
seizure. when preeclampsia progresses to eclampsia, clear and maintain open airway, give oxygen, administer mag, assess BP and fetal HR
Butorphanol tartrate (Stadol)
is an opioid analgesic that provides systemic pain relief during labor. DO NOT use with opioid addicts bc of strong withdrawal symptoms.
