Naegele’s Rule
1st day of last menstrual period + 7 days - 3 months + 1 year = estimated due date (EDD)
Fetus development Weeks 1-4
fertilized egg grows, water tight sac forms around it creating the amniotic sac, placenta develops, primitive face is formed and heart tube develops
Fetus development Weeks 5-8
facial features continue to develop, neural tube is well formed, 6 weeks heartbeat can be detected by U/S
Fetus development Weeks 9-12
hands, arms, fingers, feet and toes are fully developed, will begin to open and close hands, by end of third month fetus is fully formed; all organs and limbs are present and will continue to become functional, circulatory and urinary symptoms are functional
All or nothing effect
If exposed to harm before the end of month 1 the placenta will either not develop and attach and miscarriage will occur OR there is no effect and placenta will develop and attach and pregnancy continues
the embryo is referred to as a fetus beginning at week ___
8
The risk of miscarriage goes down after the first trimester because _______________ and the most symptoms are experience in this time because
most of the development has already taken place; symptoms occur because of all the development going on
Fetus development Weeks 13-16
fetal HR now audible with doppler consistently, facial features develop and nervous system is starting to function
Fetus development Weeks 17-20
fetus is developing muscles and is exercising, hear and lanugo begin to develop, skin becomes coated with vernix caseaosa
Fetus development Weeks 21-24
eyelids begin to open, fetus responds to movement or increased maternal HR
If born prematurely baby may survive if born after ____ weeks
23 weeks but will require a very long NICU stay
Fetus development Weeks 25-28
fetus begins to develop body fat and hearing is fully developed, changes position frequently and will respond to stimuli (sound, pain, light). Fetus likely to survive if born after the 7th month
Fetus development Weeks 29-32
Kicking increases and there is rapid brain development, fetus can see and hear
Fetus development Weeks 33-36
lungs complete development, there are coordinated reflexes and fetus becomes more responsive to stimuli
Fetus development Weeks 37-40
Labor can happen any time, movement decreases as space becomes tighter in the womb, if not in right position provider will discuss changing fetal position prior to delivery
term = ___ weeks
full term = ___ weeks
term = 37
full term = 40
Nutrition in pregnancy
lean protein options are ideal, healthy fats for development of fetal organs and placenta, about 300 additional calories to support their growing fetus
Folate or folic acid helps to
prevent birth defect of the spine and brain (neural tube defects)
Iron
helps mother create more blood and oxygen carrying capacity to support fetal oxygenation
DHA
omega 3 fatty acid important for eye and brain development in fetus
Iodine
vital for fetal brain and nerve growth
calcium and vitamin D
fetal bone and teeth development, and overall maternal health in pregnancy
foods to avoid in pregnancy
fish high in mercury, cold deli meats, raw meats and eggs, unpasteurized dairy products, liver, unwashed produce, alcohol, caffeine (no more than 200mg/day)
Drugs to avoid in pregnancy
NSAIDs, ACE inhibitors, ARBS, Retin A, sulfonamide an fluoroquinolone abx, codeine, warfarin, benzos, castor oil, mineral oil, bismuth subsalicylate, isotretinoin
prenatal / antepartum testing
blood type, Rh factor, STI testing, glucose test, UA, U/S, NST, GBS, kick counts
infant is put at risk for erythroblastosis fetalis when
mother is Rh negative and baby is Rh positive
