What is the purpose of preconception care?
|
-to facilitate the efforts of a woman/partner to be HEALTHY before pregancy so as to have a better chanace of having a HEALTHY baby
|
|
|
when should preconception care begin?
|
3 months prior to conceiving
|
|
|
What is the goal of preconception care?
|
-to ID areas that may be unfavorable to preganancy
|
|
|
what do these risk factors cause duing preganancy:
Smoking? alcohol? decreased folic acid? contraceptives? Some OTC drugs? |
Smoking- low birth weight, fetal nicotine addiction
alcohol-mental retard, fetal alcohole syndrome decreased folic acid - neural tude issuses contraceptives- decreased folic acid Some OTC drugs- teratogens |
|
|
The period of greatest enviro sensitivity and consequence risk for the developing embryo is betw/ ?
|
days 17 and 56 after conception (the embryonic phase)
|
|
|
key areas of the preconception health history are the ? (6)
|
- immunization status
-underlying medical issues -reproductive heatlh -nutrition -lifestyle -meds, OTC ones too |
|
|
FSH is responsible for?
|
for maturation of the ovarian follicle
-most important during the first week of the follicular phase of the reproductive cycle |
|
|
LH is responsible for?
|
needed for the final maturation of preovary follicles and lutenization of the ruptured follicle
-ruptures the follicle basically |
|
|
estrogen is responsible for?
|
-helps lay down lining in the uterus
-also: -needed to develop and mature the follicle -increases size of uterus -decreases after ovulation as porgesterone dominates |
|
|
Progesterone is responsible for?
|
-allows pregnancy to be maintained by having a calming effect on the uterus (and rest of body too)
-is secreted by the corpus luteum, then the placenta -increases ur body temp by .5- 1 degrees b4 menses |
|
|
Prostaglandin is responsible for?
|
-helps uterine motility
-causes cervix mucus to be more helpful to sperm by way of getting into the uterus |
|
|
the normal reproductive cycle consists of which two cycles?
|
the ovarian cycle (ovulation occure and is associated w/ the developing egg) and the endometrial cycle ( menstration occurs)
|
|
|
the ovarian cycle consist of 3 phases what are they?
|
1. the folicular phase- day one of period to ovulation, ovary grows and matures an egg (length can vary)
2. ovulation- relase of mature egg (occurs 14 days b4 menses no matter what) 3. luteal phase-begins (day 15)@ ovulation and last till next menses begins, in this phase the corpus luteum secretes increasing amount of hormone which perpares endometrial lining for implantation |
|
|
mentration starts during which phase?
|
follicular phase (ovarian cycle) and the mentrual phase (uterine cycle)
|
|
|
progesterone starts being secreted during?
|
ovulation (b/c its secreted by the corpus luteum)
|
|
|
pre-embryonic phase starts? also what going on in this phase
|
-first 2 weeks after fertilization (w/n 12 hours)
-biggest thing going on- cellular multiplication and implantation |
|
|
embryonic phase goes from ? also what going on in this phase
|
-from 2-8 wks
-rapid cell division and differentiation -the fetal membranes (3 layers), amniotic fluid, and placenta form now |
|
|
sufficient amounts of amniotic fluid help do what for fetus?
|
-help maintain constant body temp
--permit symmetric growth and development -cushion the fetus from trauma -allow the umbilical cord to be relatively free from compression -and promote fetal movemetn to enhance musculoskeletal deveoplment |
|
|
oligohydramnios (<500 mL of amniotic fluid @term) is associated w/ what?
|
uteroplacental insufficiency (insufficient blood flow to the placenta) and fetal renal abnormalities
|
|
|
hydramnois (>2,000 mL of amniotic fluid @term) is associated w/ what?
|
-maternal diabetes, neural tube deffects, chromosomal deviations, and mainly GI issuses that prevent normal swallowing of amniotic fluid by fetus
|
|
|
the placenta helps the baby do what? and protects the baby from what?
|
help protect the fetus from immune attack by mom, and removes waste products from the fetus
|
|
|
feuts should be moving clearly @ the latest which wk?
|
20th week
|
|
|
sex can be determined by at least which wk?
|
16th week
|
|
|
organogenic period is betw/ which weeks and is ?
|
@ 4-8 wks. and is the most critical period of development of congential abnormalities of "3 layers"
|
|
|
teratogen effect are @ greatest risk to fetus
betw/ which wks? |
2-9 wks
|
|
|
4 causes of abnoramlities during the organogenic period are?
|
-genetic, enviro, multifactoral, 50-60% unknown
|
|
|
what are some tetatogenic agents?
|
any agent such as a drug, virus, or radiation that can cause development of an abnormal structure in embryo, fetus
|
