OB RNC – Questions With Correct Solutions (A+)
Variable decelerations Correct Answer - HR up or down, cord
compression = VERY BAD
Prolapsed cord= push head up, change mom position
Twin-twin transfusion syndrome Correct Answer - Blood flows
unevenly between babies and you have a donor twin w/ decreased
blood volume and a recipient twin w/ increased blood volume
chronic twin to twin transfusion syndrome Correct Answer -
Between 12-26 weeks, most serious b/c they can't be delivered d/t
immaturity / most do not survive if they do / have multiple birth
defects
Acute twin to twin transfusion syndrome, Correct Answer -
Occurs when there is a huge difference in blood flow between the
twins. Could be related to death or illness in one twin which floods
the recipient twin with volume. Better prognosis though w/ ATTS.
folate deficiency is a high risk for what?! Correct Answer -
Neural tube defects
Folic acid amounts Correct Answer - 0.4-0-8g
400-800mg
Maternal lupus is a high risk for what in newborn? Correct Answer
- High risk of heart block
Lupus mom taking steroids during pregnancy needs what during
labor? Correct Answer - A stress dose of steroids which can
lead to increase incidence of NEC IN INFANT
Hydrops fetalis Correct Answer - Rh- mom attacks the rh- fetus
,(immune response)
Hyperthyroid moms have an increased risk of what? Correct
Answer - Preterm delivery (PTD)
Hypothyroid moms (Hashimotis) leads to what? Correct Answer -
-infertility issues
-preterm delivery (PTD)
-increased risk of fetal brain and spinal cord issues
what will cause immediate withdrawal for a drug addict taking
methadone? Correct Answer - Nubain / stadol
Foods to avoid w/ pytalism? Correct Answer - Starchy foods
What is pytalism Correct Answer - Excessive amounts of saliva
Amniocentesis Correct Answer - needle puncture of the
amniotic sac to withdraw amniotic fluid for analysis
Amniocentesis timeframe + risks Correct Answer - Around 14-
20 weeks
before 14 weeks = increased risk of clubfoot
15-16 weeks = increased risk for respiratory distress
L/S ratio Correct Answer - The lecithin-sphingomyelin ratio is
a test for assessing fetal lung maturity. An L/S ratio of 2 or more
indicates a relatively low risk of infant respiratory distress
syndrome, and an L/S ratio of less than 1.5 is associated with a high
risk of infant respiratory distress syndrome
diabetics need a 3:1
,L/S ratio = what an give false ratios? Correct Answer -
Contaminated amniotic fluid (blood or meconium) can give false
ratios
CVS (chorionic villus sampling) Correct Answer - A procedure
where a needle is inserted into the chorion and tiny hair cells are
extracted that contain genetic material from the fetus. The cells are
analyzed for genetic defects. Can be done as early as 10th week of
pregnancy
CVS can't diagnose what? Correct Answer - NTD (Neural tube
defects) & spina bifida
Early decelerations Correct Answer - Head pressed on. This is
ok.
vagal nerve response
How long is an NST reassuring for? Correct Answer - 24 hours
BPP Correct Answer - -Fetal breathing movement
-Fetal movements of body or limbs
-Fetal tone
-Amniotic fluid volume
Reactive fetal heart rate (FHR) with activity (reactive non-stress test
[NST])
*Scores of 8 (with normal amniotic fluid) and 10 considered normal
Bpp is reassuring for how long Correct Answer - 7 days
Presence of moderate variability means what acid base wise?
Correct Answer - Absence of acidemia
, Presence of access means what? Correct Answer - Absence of
acidemia, but ABSENCE of access cannot reliably predict acidemia
Is there a baseline in marked variability? Correct Answer - NO.
Variable decels Correct Answer - FETAL HYPOTENSION d/t
cord compression
Shortened R to R interval Correct Answer - tachycardia
Prolonged R-R interval Correct Answer - fetal bradycardia
SVT fetal heart rate Correct Answer - 200-300 bpm
treatment is digoxin
SVT treatment in newborns? Correct Answer - Digoxin
Sinusoidal pattern - think what? Correct Answer - Maternal /
fetal hemorrhage
fetal anemia
What to remember about moderate variability? Correct Answer -
Mature CNS system
sympathetic nervous system Correct Answer - SPEED -fight or
flight
epi / norepinephrine
alpha cells
parasympathetic nervous system Correct Answer - POKE - rest
and digest
acetylcholine
beta cells
