week 2 content Flashcards
which screening is a prenatal blood test done during 15-22 weeks pregnancy to assess the risk of certain birth defects in the developing baby.
It measures the levels of four substances in the mother’s blood: and helps identify an increased risk for:
down syndrome
Edwards syndrome
Neural tube defects - spina bifida
MSAFP “Quad screen”
which screening is used to assess the risk of certain chromosomal abnormalities in the developing baby such as:
down syndrome
patau syndrome
Edwards syndrome
problems with # of sex chromosomes
Noninvasive prenatal test (NIPT) or cell free DNA
after delivery does maternal insulin requirements i/d
why is breastfeeding encouraged in DM moms
decrease
glucose leaves body through breast milk

what scenario would we give this med?
28 weeks T/F
before/after spontaneous or induced abortion of ectopic preg
before/after invasive procedure during preg
before/after maternal trauma
Rh immune globulin IM (Rhogam)
- at 28 weeks
- After spontaneous or induced abortion of ectopic preg
- After invasive procedure during preg

increase
no change - sodium
increase
increase
increase
no change - iodine

patient A is being screened for gestational DM with 1 hour GTT
does she need to fast?
her glucose came back at 150. Did she pass or fail?
- 1 hour GTT (glucose tolerance test)
- Don’t have to fast
- > 140 = failed
what should the nurse tell the mom that is 37 weeks that called c/o contractions/cramping?
think preterm or term, frequency and other associated signs
could be labor!
- Counsel to go to hospital when contractions are 5 mins apart, getting stronger every hour, or if water breaks
if contractions/cramping is:
- Associated with heavy vaginal bleeding (more than spotting/bloody show)
- Change in fetal movement
common discomforts - round ligament pain
cause -
when to be concerned -
teaching -
- Cause
Weight of uterus stretching round ligament - When to be concerned
If pain is moving (not transient) - Teaching
Warmth to abdomen
Slow changes from lying to sitting/standing
what should the nurse tell the mom that is 20 weeks that called c/o contractions/cramping?
think preterm or term, frequency, cause, and other associated signs
less then 37 weeks = preterm
preterm if contraction/cramping is:
- Rare/occasional
- Associated with cause like increased activity
- associated with Normal fetal movement, no vaginal bleeding/leaking of fluid
OK
preterm if contraction/cramping is:
- Regular (>4-6/hour)
- associated with no cause
- associated with Change in fetal movement, vaginal bleeding, or leaking of fluid
NOT OK
10 weeks gestation patient presents with

what should the nurse suspect?
threatened abortion
ectopic pregnancy

ectopic pregnancy
Uni-lateral abdominal pain = big giveaway
iron deficiency vs sickle cell vs folic acid anemia?
Treatment – prevent crisis, IV fluids, O2, abx, folic acid, analgesics
Treatment – folic acid 400 mcg before pregnancy, 1 mg during pregnancy
Treatment – supplemental iron
sickle cell

BPP
how do we screen for gestational DM
1 hour glucose tolerance test
3 hour GTT
which stress test evaluates oxygenation and carbon dioxide exchange of the placenta
contraction stress test
what is the desired score on a contraction stress test - negative or positive?
- negative test = desired score, no late decelerations, no signs of fetal distress
- positive test = bad, late decelerations, signs of fetal distress, consider preparing for C/S
which technique assesses fetal well-being by using high frequency sound waves to deflect off tissues in the uterus to a transducer showing structures

- Prop up HOB
ABO incompatibility
Maternal serum antibodies against ___ and ___ are present
hemolysis of fetal RBC leads to hypobilirubinemia/hyperbilirubinemia
will an indirect/direct combs test be conducted?
would we expect mild/severe anemia to occur?
Maternal serum antibodies against A and B are present
hyperbilirubinemia
Cord blood – (direct combs test) – Done on cord/infant blood, Detects if maternal antibodies are adhered to infants RBC
Mild anemia may occur, severe anemia doesn’t generally occur
Gestational trophoblastic disease:
type - ___________________-
abnormal development occurs in the fertilized egg, not a viable pregnancy
Molar pregnancy (hydatidiform mole)
partial molar pregnancy vs complete molar pregnancy
(abnormal ovum + normal sperm)
(normal ovum + abnormal sperm)
- Complete mole – (abnormal ovum + normal sperm) ovum containing no genetic material is fertilized by normal sperm
- Partial mole – (normal ovum + abnormal sperm) normal ovum is fertilized by 2 sperm or sperm that hasn’t divided
when should mom seek care if she thinks fetus is moving less or not at all?
Go to HCP if <10 movements in 2 hours
advanced maternal age =
medical risks associated with AMA

35
increase in all
which type of genetic test identifies individuals who carry a gene mutation for a specific genetic condition.
These individuals typically don’t experience any symptoms of the condition themselves.
However, they can pass the mutated gene on to their biological children.
carrier screening
common discomforts - ankle edema
cause -
when to be concerned -
teaching -
- Cause
- Decreased venous return
- When to be concerned
- Generalized edema
- Sudden weight gain
- Headaches
- Visual changes

- Avoid prolonged sitting or standing
- Keep feet and legs elevated
- Compression socks
- Avoid constrictive clothes, esp around waist
- Exercise
- fluids
what should the nurse tell the mom that is 38 weeks that called c/o vaginal bleeding?
think preterm or term and amount, cause
Term (37 weeks or more)
- If cause can be identified (activity, sex, exam) = OK
- spotting with contractions = OK, labor!
- If cause can’t be identified = may evaluate for labor/problems
- persistent bleeding, no known cause = NOT OK, go to hospital
patient A - has high BMI, hx of DM and HTN
Is she high risk or low risk? when should she be screened for DM?
patient B - has normal BMI, no hx of DM or HTN
is she high risk or low risk? when should she be screened for DM?
patient A
High risk – screen as early as possible
patient B
Low risk – screen 24-28 weeks
diagnostic vs screening test?
Noninvasive prenatal test (NIPT) or cell free DNA
MSAFP “Quad screen”
carrier screening
all screening tests, not diagnostic
what should the nurse tell the mom that is 37 weeks that called c/o leaking fluid?
think preterm or term and type of fluid
Term (37 weeks or more)
- Leukorrhea – clear/white liquid, no/mild odor = normal, not labor
- Urine – teach practice Kegels = normal, not labor
- Amniotic fluid = go to hospital, labor!
Consider amount – spotting ok, large amount like having to wear a pad to catch the fluid = too much fluid needs further investigation
which one?
- Partial/Complete mole – (abnormal ovum + normal sperm) ovum containing no genetic material is fertilized by normal sperm
- Partial/Complete mole – (normal ovum + abnormal sperm) normal ovum is fertilized by 2 sperm or sperm that hasn’t divided
- Complete mole – (abnormal ovum + normal sperm) ovum containing no genetic material is fertilized by normal sperm
- Partial mole – (normal ovum + abnormal sperm) normal ovum is fertilized by 2 sperm or sperm that hasn’t divided

group of rare tumors that develop in the uterus after conception.
Proliferation of trophoblastic cells
type - molar pregnancy
Gestational trophoblastic disease
which is more severe
ABO incompatibility or Rh incompatibility
Rh incompatibility

does she have to fast?
BS 1: 160
BS 2: 130
BS 3: 145
BS 4: 130
did she pass or fail?
- Have to fast
- Test BS 4 times, if elevated 2+ times = failed
big 4 dangerous things to ask mom about
fetal movement/kick count
contraction/cramping
leaking
bleeding
what test produces sound/vibration to stimulate fetus
which should cause accelerations in FHR should show on fetal monitor
fetal acoustic stimulation and vibroacoustic stimulation test
which scenario are we concerned could to Rh incompatibility?
1st pregnancy mother who is Rh- carrying a Rh+ fetus
2nd pregnancy mother who is Rh- carrying a Rh+ fetus
Why?
2nd pregnancy mother who is Rh- carrying a Rh+ fetus
1st pregnancy she wouldn’t have developed antibodies already so we can prevent it.
2nd pregnancy she has probably already developed Rh antibodies from a previous pregnancy so Rhogam won’t be effective in preventing complications in the current pregnancy.
which test Shows fetus ability to respond to its environment by acceleration of FHR with movement
- Monitors are placed on belly which show:
- accelerations of fetal HR with movement or contractions
- adequate oxygenation and intact CNS
non stress test
