26
rubella issues
can infect all 3 germs layers during embryonic period; vaccine is live so do not get pregnant for 4 weeks following
27
Rh issues
Rh is present on surface of RBC; Rh- mother with Rh+ fetus can cause sensitization if RHOGAM not administered; next pregnancy with Rh+ infant can cause hemolysis
28
betamethasone
corticosteroids that promote fetal lung maturity usually following tocolytic to slow preterm birth
29
direct coombs test
used to determine hemolytic disease of newborn due to Rh or ABO incompatibility; positive test result means you have antibodies that are working to destroy own RBC
30

39
STD's (STIs)
can be parasitic, bacterial, viral; can cause PID, infertility, cancer, chronic hepatitis
40
true labor
1. presence of regular phasic uterine contractions increasing in frequency and intensity 2. progressive cervical effacement and dilation, discomfort begins in back then radiates to abdomen, sedation does not diminish contraction, show usually present
41
false labor
irregular contractions, no regular pattern, discomfort in lower abdomen and groin, show not present, no cervical change, contractions might stop when walking/rest, sedation stops or decreases contractions
42
contraceptives
natural family planning, barrier methods, hormonal methods, IUD's, surgical
43
signs of ovulation
increased maternal estrogen levels (d/t LH surge), leukorrhea (increased discharge), pH of vagina becomes more alkaline (more favorable for sperm)
44
ABO blood compatibility
most common incompatibility is mother=O and infant type A or B
45
genital herpes
painful genital lesions that may be present internally or externally; up to 60% transmission rate from maternal-fetus with those who acquire herpes near time of delivery; less than 2% for those with recurrent herpes; treat with aycyclovir and antirviral therapy; c-section if active outbreak
46
fetal heart rate decelerations
indicative of fetal distress; decrease in HR; VEAL CHOP
47
neonatal abstinence syndrome
infants from substance abusing mothers; may be irritable (6-8 weeks), jittery, reduce withdrawals, promote adequate respiration/temp./nutrition, swaddle,
48
symptoms of hypoglycemic infant
jittery, tachypnea, diaphoresis, hypotonia, lethargy, apnea, temperature instability
49
syphilis in pregnancy
chancre or ulcer in mom and can lead to CNS and cause organ damage; can cause preterm birth, physical deformity, neurological complications, still birth, or neonatal death; transplacental transmission; treat with penicillin

54
normal percent weight loss after birth (newborn)
lose up to 7% of birth weight
55
GBS treatment
if mom positive at 35-37 weeks, treat with penicillin or ampicillin to prevent transmission to fetus
56
phototherapy nursing considerations
assessments (VS, feeding, bowels), warmth (cold stress, acidosis), phototherapy (cover eyes, genitalia), tactile stim., readjust position q2hours, answer parent question/concerns
57
normal post partum bleeding
58
abnormal postpartum bleeding
saturating pad within 1 hour; saturating pad within 15 minutes is extreme; rubra after day 4; foul odor;from alba to bright red bleeding
59
contraceptives avoiding during breast-feeding
do not use estrogen; it can decrease milk supply
60
Vitamin K
intramuscular vaccination given to newborn to prevent hemorrhagic disease
61
natural family planning contraception
24% failure rate; need to have proper awareness of own body including temperature (increase in basal metabolic rate) and vaginal discharge (clear egg white like is fertile compared to white secretion)
62
transition phase of labor
8-10 cm; short but intense, contractions every 1.5-2 minutes for 60-90 sec; very irritable; may lose control; N/V common
63
epidurals
epidural: anesthetic injected into epidural space that allows for mother to walk and decreases pain; spinal: 100% block of sensation and motor function
64
HIV in pregnancy and transition to newborn
early antiretroviral and lessen chances of transmission to fetus (less than 2% with treatment); 15-25% chance of maternal-fetal transmission without treatment; treatment is anteviral and c-section; avoid breast-feeding
65
postpartum depression
occurs in 10-20% of all postpartum patients; pervasive sadness, mood swings, fear, anger, anxiety, unable to care for self or infant, irritability that may lead to violence, rejection of infant, obsessive thoughts
66
chlamydia
usually asymptomatic in women but can cause burning sensation while urinating; presence during birth can cause fetal conjunctivitis or premature birth; treat with oral antibiotics
67
variable decelerations
present in between contractions; indicative of cord compression; requires maternal movement or manual manipulation of fetus off of cord
68
CVS
used to diagnose fetal chromosomal abnormalities; earlier use then amniocentesis (~10 weeks gestation)

hemorrhage then lower uterine not responsive to oxytocin (use methergine)
73
placenta abruption
premature separation of normally implanted placenta; sudden onset of intense sharp abdominal pain; vaginal bleeding may or may not be present; port-wine stained amniotic fluid
74
risk factors for placental abruption
HTN, seizures, blunt trauma, short umbilical cord, previous abruption, cocaine use
75
maternal serum AFP (MSAFP)
high level = neural tube defect (spina bifida); low level = might indicate down syndrome

HPV, HIV, HSV, Viral Hep A and Hep B
83
GTPAL
gravida- number of pregnancies (including current one); term- birth to term infants (37 weeks); preterm- birth to preterm infant (20-36.6 weeks); abortions- miscarriages/abortions; Living- number of living children currently
84
toxoplasmosis
caused by parasite; can cause flu-like symptoms but most are asymptomatic; causes chorioretinitis, hydrocephaly, microcephaly, intracranial calcifications
85
other (torch)
syphilis, GBS, varicella zoster, HIV, parvovirus B19
86
cytomeglovirus (CMV)
can be transmitted by primary infection, reinfection with different strain, or reactivation of previous infection during pregnancy; greatest risk in 3rd trimester; most common non-genetic cause of childhood hearing loss
87
ovulatory phase begins...
when estrogen peaks and ends with release of oocyte from mature graafian follicle known as ovulation
88
12-36 hours prior to ovulation
LH levels surge, estrogen begins to decrease, progesterone starts to increase
89
graafian follicle matures d/t
LH and FSH released from pituitary; mature graafian follicle produces estrogen
90
ovarian cycle
follicular phase begins after first day of menstruation and lasts 12-14 days, then ovulation occurs, then luteal phase occurs for 14 days following ovulation
91
luteal phase consists of
empty follicle cells morph to corpus luteum to produce high levels of progesterone and low levels of estrogen, if pregnancy occurs then placenta takes over this function; if it does not occur corpus luteum degenerates and decreases progesterone leading to menstruation
92
endometrial cycle
has to do with the changing of the endometrium in uterus corresponding to hormones released during ovarian cycle; consists of proliferative phase, secretory phase, menstrual phase;
93
proliferative phase
occurs following menstruation and ends with ovulation; endometrium thickens and becomes more vascular in preparation for implantation of zygote; occurs as result of increasing estrogen from graafian cell
94
secretory phase
begins after ovulation and ends with menstruation; endometrium continues to thicken d/t release of progesterone secreted from corpus luteum; if pregnancy does not occur then endometrium and corpus luteum begin to degenerate
95
menstrual phase
occurs as result of hormonal changes and results in sloughing off of endometrial tissue
