Maternity Flashcards
Cardiovascular system
Pulse may increase 10b/minutes
Blood pressure
May decrease in second trimester
 Endocrine system
BMI raises, body weight increases
Respiratory system
Oxygen consumption increases by 15% to 20%
Gastro intestine system
Nausea, vomiting, constipation,and hemorrhoids
renal system
Frequency of urination increases in first and third Trimester
Reproductive system
Uterus enlarges, cervix changes.
Leukorrhea is normal- White milky discharge PV-due to hormonal changes (if foul smelling /itching/ burning-need to report)
Skin
Linea Negra /striae(stretch marks)/chloasma(blackish color on the face)vascular spider Navi (very very small and tiny-blood vessels)
Skeletal system
Center of gravity changes -lordosis
Weight gain during pregnancy
Weight gain 11.2 to 15.9kg KG (25 to 35 LB) 1st trimester 1 to 2kg(2.2to4.4lb) 2nd to3trimester 0.4 KG (1 lb) under weight woman total 28 to 40 gain Overweight woman 15 to 25 Lb
Pica
Pica is the abnormal, compulsive craving for and consumption of substances normally not considered nutrionally not valuable or edible
Common substance include ice,corn starch, chalk,clay,dirt,and paper
associated with iron identification anemia.so monitor the Hb and Hct.
Laboratory tests Blood type and Rh factor
mother is Rh negative and it has negative antibody screen should be given Rho(D)immune globulin (RhoGAM) within 72 hours of birth of first baby when detected
With every other pregnancy, should be given RhoGAM at 28 week ago gestational and within 72 hours of birth of baby
Other pregnancy tests
Tuberculin-skin test (if needed) positive test indicates need for chest x-ray to rule out active disease. In Pregnant client, x-ray cannot be performed until after 20th week of gestation
urine glucose-?Diabetes, protein-? Preeclampsia,nitrates and WBC? Infection
May be decreased and a specific gravity may be increased (vomiting )
blood:hCG levels (human chorionic gonadotrophin)
diagnostic test: ultrasonography
outline define identifies fetal and maternal structures.
Assist in confirming gestational age and estimated date of confinement.
Avoid supine position-reduced venous return -hypotension dizziness,fall
Chorionic villus sampling (high risk)genetic problem
Assessment of portion of the developing placenta (chronic villi) which is aspirated through a thin sterile catheter accident or syringe (10 to 12 weeks)
detects genetic abnormalities by sampling chronic villus tissue at 8 to 12 week of gestation
kick counts (fetal movement counting)- 10 times into 2hrs.
amniocentesis
Aspiration of amniotic fluid may be done from 13 to 14 weeks of gestation
Used to determine genetic disorders, metabolic defects , fetal lung maturity.
Risks maternal hemorrhage,infection,abruptio placenta, premature rupture of membranes.
(AFP)alpha-fetoprotein can be measured from the amniotic fluid
high levels of AFP are associated with neural tube defects,anencephaly (incomplete development of fetal skull and brain), Omphalocele(abdominal wall defect)
Amniosynthesis:high levels of AFP.
High levels of AFP also May be present with a normal multi fetal pregnancies
Low levels of AFP are associated with chromosomal disorder (down syndrome) or gestational trophoblastic disease (hydatidiform mole)
fetal lung test
Lecithin/Sphingomyelin(L/S)ratio is 2:1ratio indicating
fetal lung maturity (2.5:1or 3:1for a client who has diabetes mellitus)
Present of phosphatidylglycerol(PG)

Absence of PG is associated with respiratory distress
after amniocentesis:administer Rho(D)immune globulin RhoGAM to the client if she’s Rh negative
advise the client to report to her provider if she’s experience fever, chills, leakage of fluid, or bleedingfrom the incision site, decreased fetal movement, vaginal bleeding,or uterine contractions after the procedure
Fern test
Microscopic slide to determine in presence of amniotic fluid leakage
Nitrazine test
Determines present of amniotic fluid in vagina secretions; shades of blue indicate that membranes probably ruptured. blue green/ blue gray/ deep blue = positive
Quad marker screening
A blood test that ascertain information about fetal birth defects,it does not diagnose the actual defect. Check HCG,AFP, Estriol,inhibin-all proteins from fetus and placenta
Sustained Fetal Tachycardia
> 160/min for>10mts is concerning finding that requires further follow up
Nonstress test positive - reactive it’s normal
Performed to assess placenta function and oxygenation
Assesses fetal well-being-FHR-vs fatal moment
Normal increased the fetal heart rate with fetal movement
outpatient clinic external monitor
the non stress test is reactive- (normal) when 2 or more fhr acceleration of at least 15 beats/mts (each with a duration of at least 15 seconds ) occur in a 20 minuets Period Test
(wait at least for 40 minutes if no fetal heart rate acceleration, before saying it it’s abnormal)
contractions stress test(positive is abnormal)
Performed to access placental function, oxygenation and baby tolerated labor ?
Fetal heart rate versus contractions -nipple stimulation/ oxytocin(Oct)
Normal-no late deceleration, no variable deceleration
early decerlaration is OK -due to head compression to maternal pelvis
assess fetal ability to tolerate labor,fetal well-being
late deceleration and variable decelerations: not OK uteroplacental insufficiency
A variable decelerations- maybe due to cord compression, cord prolapse, uterine tachysystole ( first constructions) chorioamnionitis, Pleasant abruption, nactual cord , PROM with the fetal distress,maternal pushing during labor.
Late decelerations:due to decreased cardiac output from mother/ decreased blood to the placenta :
common causes maternal dehydration, anemia, hypoxia, hypertension epidural analgesia , uterine tachysystole, placental abruption.
Fetal monitoring
External fetal monitoring: non-invasive, performed using transducer or Doppler
Transducer,fastened with belt,should be placed on side of mother where fetal back is located (find using Leopold’s maneuvers)
Internal fetal monitoring invasive , requires rupturing of membranes,
attachment of electrode to presenting part of fetus, mother must be dilated 2 to 3 cm to perform this procedure
contraindications-closed cervix, placenta previa,STD, breach, AIDS, hepatitis B.
fetal assessment biophysical profile BPP
Check fightings on score 0 to 20 by Dr. with the help of ultrasound
1-fetal heart rate/NST
2-fetal breathing moment
3-fetal body movements
4-Fetal muscle tone
5-amount of amniotic fluid
score 8 to 10=reassuring=good
6-Equivocal (suspicious)need another BPP With in the next 12 to 24hrs
4 or less non-reassuring- may needed immediate attention/delivery
Nagele’s Rule
to estimate date of confinement,delivery date:
1-subtract 3 months from the first day of the last menstrual period,
2-add 7 days,and
3-Adjust the year
McDonalds Method-
Fundal height-correlate with you gestational age until 3rd trimester. Consistency (same person same measurement) is important
GTPAL acronym: Gravidity number of pregnancies
Nulligravida woman has never been pregnant.
primigravida: a woman in her first pregnancy,
multigravida: a woman who has had two or more pregnancies
GTPAL acronym
G= gravida T- term baby P-preterm Baby A-abortion L- living
Gravida
The number of times the woman has been pregnant, regardless of pregnancy outcome
Term term
The number of pregnancies delivered at 37 weeks zero days and beyond
Preterm 
The number of pregnancy delivered from 20 weeks zero days gestation through 36 weeks six days risk gestation
Abortion
The number of pregnancy sending before 20 weeks zero days gestation this may be spontaneous miscarriages are induced abortions
