92
2 Digit System
G (Gravidity): total # of pregnancies P (Para): indicates the # of pregnancies that have completed 20 weeks gestation and beyond regardless of outcome (live or not) reached
93
T or F: Pregnancy and birth are normal, healthy processes.
TRUE
94
Where does the placenta usually attach in the uterus?
fundus upper uterus
95
Maternal-placental-embryonic circulation is established by day ___, when the embryo’s heart begins beating
day 17
96
Placenta
structure of the placenta complete by: week 12 grows wider until: week 20 then continues to grow thicker endocrine gland that produces four hormones to maintain the pregnancy and support the embryo/fetus:
97
4 hormones produced by the placenta
1) Human chorionic gonadotropin (hCG) 2) Human chorionic somatomammotropin or human placental lactogen (hPL) -similar to growth hormone 3) Progesterone -endometrium, decreases the contractility of the uterus, and stimulates maternal metabolism and development of breast alveoli 4) Estrogen -stimulates uterine growth and uteroplacental blood flow, causes a proliferation of the breast glandular tissue, stimulates myometrial contractility
98
Cotyledons
functional unit of the placenta 15 to 20 if they break off and are still in the uterus, can cause hemorrhaging why you inspect the placenta afterwards
99
Amniotic fluid overview
amniotic cavity is first filled with fluid derived by the maternal blood by diffusion fluid secreted by the respiratory and GI tract of the fetus then enters the amniotic cavity
100
Functions of the amniotic fluid (6)
1) constant body temperature - thermoregulation 2) source of oral fluid and reposition for waste 3) cushions the fetus from trauma 4) allows freedom of movement for MSK development 5) barrier to infection 6) allows lung development (practice swallowing and breathing)
101
Components of amniotic fluid (many)
albumin, urea, uric acid, creatinine, lecithin, sphingomyelin, bilirubin, fructose, fat, leukocytes, protein, epithelial cells, enzymes, and lanugo hair
102
Normal amount of amniotic fluid by term
700 - 1,000 mL
103
oligohydramnios
less than 300ml associated with fetal renal abnormalities
104
polyhydramnios
more than 2000ml associated with GI and other malformations
105
How to determine if amniotic fluid amount is normal
ultrasound to measure amount of amniotic fluid
106
Oxygen and nutrients are brought through the ________________ to the developing fetus
umbilical cord
107
Umbilical cord
at term: 2cm thick and 30-90cm in length normally attached centrally to the placenta
108
Cords (3)
2 arteries -deoxygenated blood, small -carry blood from the embryo/fetus to the chorionic villi -sometimes 1 artery 1 vein -oxygenated blood, large -returns blood to the embryo/fetus
109
Wharton's Jelly
connective tissue that surrounds umbilical cord prevents compression of the blood vessels to ensure nourishment to the embryo/fetus
110
Nuchal cord
when umbilical cord wrapped around baby's neck BAD
111
Fetal Membranes (2)
1) Chorion - outer layer 2) Amnion - inner layer
112
Chorion
develops from the trophoblast contains the chorionic villi on the surface becomes the covering of the fetal size of the placenta contains major umbilical blood vessels that branch out over the surface of the placenta
113
Amnion
inner cell membrane that develops from the blastocyst developing embryo draws the amnion around itself to form a fluid-filled sac becomes the covering of the umbilical cord and covers the chorion on the fetal surface of the placenta
114
Prenatal Care
Multidisciplinary Individualized schedule of care Group prenatal care Practitioner: Fam MD, OB, direct-entry midwives (low risk pregnancy), doula (labour/postpartum support; no clinical tasks) Birth setting choices: hospital, birth center, home birth, factors increasing the safety of birth at home
115
Prenatal Care Frequency
initial visit: 1st trimester monthly visits: until 28 weeks visits every 2 weeks: until 36 weeks weekly visits: until birth
116
Purpose of prenatal care
identify existing risk factors and other deviations from normal health promotion preventive care and self-care
117
T or F: Lack of prenatal care doesn't actually influence birth outcomes.
FALSE Lack of prenatal care linked to less positive birth outcomes, higher rates of complications
