Women and Families Flashcards
Non-stress test
measures fetal well-being; started around 34 weeks for normal risk pregnancy; accelerations in response to fetal movement; 2 or more accelerations in 20 minutes
contraction stress test
looks for decelerations of baby HR in response to contractions; do not want decelerations in relation to contraction; want a negative test = no decels
prolactin
hormone that stimulates milk production
Let down reflex
stimulation of the nipple by babies sucking; hypothalamus stimulates posterior pituitary to release oxytocin and anterior pituitary to release prolactin;
oxytocin
stimulates release of milk from the breast; can contribute to afterpains
BUBBLEHEB
postpartum focused exam: breasts, uterus, bladder, bowel, lochia, episiotomy, homans, emotional, bonding
breast assessment
inspect size, contour, asymmetry, and engorgement; note reddened, tender, engorgement, warmth; check nipples for cracks, redness, fissures; note if nipples are flat, erect, or inverted; educate women to wear supportive bra 24 hrs; assess correct latch if breast feeding
if women is non-lactating/breast-feeding
avoid stimulation, ice packs or cabbage leaves, mild analgesic for pain
Uterus assessment
assess women lying flat after void; support bottom of uterus during assessment (prevent prolapse); note firm vs boggy, midline vs. deviated; any lac/hematoma to vagina
bladder assessment
monitor output/assess for retention, postpartum diuresis, void within 4 hours after birth (catheterize if unable), ambulate early, assess for UTIs, auscultate bowels prior to assessing uterus
Lochia assessment
educate on stages of lochia; increase in amount, foul smell, or return to rubra is not normal; change peri pad frequently; peri care after each void if lac/episiotomy; weigh pas to get accurate blood loss volume
Episiotomy assessment
use REEDA, midline or mediolateral
peri care
peri bottls, ice packs (first 24 hours), Sitz bath (after 24 hours), topical meds (witch hazel, dibucaine, dermoplast, epifoam), pat dry front to back
1st degree lac
perineal and subcutaneous skin and vaginal epithelium
2nd degree lac
includes skin, mucous membranes, and fascia of perineal body
3rd degree lac
skin, mucous membranes, and muscle of perineal body, extends into but not through rectal sphincter
4th degree lac
extends through anterior rectal mucosa exposing rectal lumen
hemorrhoids assessment
assess for appearance and number
emotional adaptation
post partum blues (appears few days after delivery) symptoms: sadness, anger, anxiety, unable to self care or care for infant, reject infant; 10-20% of all postpartum pt; post partum psychosis can occur (hallucinations, delusions, bizarre behavior)
Bonding
determine moms phase of adjustment; take culture into account; describe level of attachment
antepartum
pregnant women before onset of labor
intrapartum
time of labor and childbirth
postpartum
6-8 week time after delivery of baby and placenta; return to non-pregnant state
involution
pelvic reproductive organs returning to approximate pre-pregnant size, position, and function
normal rate of involution
fundus/uterus descends 1cm (or fingerbreadth) per day from umbilicus
lochia rubra
first 1-3 days (bright red bleeding); shedding 9 months of accumulated substance
lochia serosa
3-10 day, pale, serosanguinous (pale red) to light brown
lochia alba
10-14 days; creamy, yellow, white (usually gone in 2 week but can last up to 6)
critical bleeding after delivery
saturating peri pad in 15 minutes or less or pooling of blood under butt
Rhogam
mother Rh -, infant Rh +; mothers antibodies attack babies; leads to complications for subsequent pregnancies; if baby is + then administer 300 mcg rhogam within 72 hours postpartum
discharge/going home
provides minimum stay; 48 hours after uncomplicated vaginal birth; 96 hours after uncomplicated cesarean birth
menstrual cycle step 1
hypothalamus releases GnRH causes anterior lobe cells to secrete FSH and LH
menstrual cycle step 2
FSH and LH promote follicle growth and maturation of oocyte, estrogen production, endometrium priming, all in ovary
menstrual cycle step 3
blood level estrogen rises stimulating surge in LH secretion
menstrual cycle step 4
surge of LH midcycle triggers ovulation and formation of corpus luteum
menstrual cycle step 5
progesterone & estrogen secreted by corpus luteum maintains endometrium if pregnancy occurs
menstrual cycle step 6
rises in progesterone and estrogen in blood inhibit FSH and LH during last phase of cycle
when does corpus luteum deteriorate
when ovum is not fertilized
conception
union of male and female ovum
sperm survival time
48-72 hours
ova fertility time
12-24 hours
fertilization
penetration of sperm into ovum
location of fertilization
ampulla in fallopian tube
capacitation
sperms ability to penetrate ovum
fertilization factors
maturation of sperm and ovum (sperm must wait 4-6 hours in female to undergo capacitation), sperms ability to reach ovum, sperms ability to penetrate ovum
zygote
fertilized sperm and ovum combined; contains all genetic material; secretes human chorionic gonadotropin
placental functions
transport & exchange: serves as lungs, kidneys, liver, GI tract, and serves as passive immunity; Hormone secretion: secretes hCG, estrogen, progesterone, hPL (human placental lactogen)
progesterone function
smooth muscle relaxant; stops women from early birth and contractions
umbilical cord
how baby is connected to mother; 2 arteries and 1 vein
embryonic period
development of 3 germ layers, development of embyonic membranes: chorion, amnion, umbilical cord, placenta
chorion
outermost layer of fetal membrane
amnion
amniotic fluid-buoyant temperature controlled environment (acts as a cushion)
umbilical cord artery/vein purpose
2 arteries carry deoxygenated blood from fetus to placenta; 1 vein supplies oxygen and nutrients to fetus; surrounded by wartons jelly
first trimester characteristics of fetus
face becomes more human; reflex activity, spontaneous movement, heart begins to beat, weighs 45g at end and is 3.5 in long, very susceptible to teratogens, organ development, fetal circulation established, sex identified
second trimester characteristics
very active (feel movement), lanugo present, vernix caseosa coats skin, brown fat forms, lungs form alveoli and surfactant, eyes open (sensitive to light and sound), weigh 700-800g and 10 in long
first trimester timeline
conception - end of week 12
second trimester timeline
week 13-end of week 26
third trimester characteristics
subcutaneous fat increases (chubby), bones soft and flexible, increase in muscle, resp. and circ. system functions, lanugo and vernix start to disappear, maternal antibodies transferred, usually positioned head down ()
third trimester timeline
27 weeks - birth
estrogen secreted from
secreted from placenta and ovaries
estrogen affects
increase uterine growth, increase breast development, increase uterine blood flow, prevents follicular development during pregnancy
progesterone secreted where
corpus luteum first then placenta
progesterone affects
relaxes smooth muscle decreasing vascular resistance, supports and maintains uterine lining for implant and development, decreases prostaglandin production
prolactin secreted where
anterior pituitary
prolactin affects
promotes development of breasts and supports lactation, release and stimulate milk production after birth
oxytocin secreted where
posterior pituitary
oxytocin affects
stimulates uterine contractions and stimulates milk ejection reflex
