Spinnbarkeit Correct Answer - fertile cervical mucus -->
stringy --> optimal time for fertility (sperm can swim_
egg white consistency
Threatened abortion Correct Answer - bleeding
cervix is closed, mild to no cramping
Inevitable abortion Correct Answer - bleeding, cramping,
dilation WITHOUT expulsion of fetal products
may need d&c due to retained placenta
Incomplete abortion Correct Answer - partial expulsion of
products
need d&c
Spontaneous/complete ab Correct Answer - complete
evacuation of all products of conception
Habitual abortion Correct Answer - 3 or more consecutive
SABs
Missed abortion Correct Answer - in utero death of
embryo/fetus
<20 weeks with retained products
s/s septic shock Correct Answer - SHOCK = low BP,
hypothermia, oliguria
SEPTIC = fever, chills, kidney failure (back pain), DIC, ARDS, death
,Reasons for miscarriages/abortions Correct Answer - -
chromosome disorders
-drugs, alcohol, smoking, infections, STDs
-hypothyroid, DM, lupus
-incompetent cervix
Antiphospholipid antibody syndrome Correct Answer -
autoimmune disorder --> attacking proteins in the blood -->
increased clotting risk
often placed on lovenox, heparin, baby asa
Why do we care about antiphospholipid antibody syndrome
Correct Answer - common cause for recurrent miscarriage and
early severe pre-eclampsia
Heparin antagonist Correct Answer - protamen sulfate
Progesterone usage Correct Answer - prevent PTL
nurtures the fetus and supports the lining of the endometriosis
--> makes it thicker (supports implantation)
MTHFR Correct Answer - blood prone to clot --> prone to have
pre-e
Maternal lead exposure Correct Answer - neuro and lower IQ
in newborn
Folic acid used to Correct Answer - prevent neuro tube defects
Caloric intake during 2nd trimester Correct Answer - 300 kcal
day
600 kcal for twins
,high A1C (>8.5) --> type of neonate problems Correct Answer -
heart defects, vascular issues
why increase risk of RDS with diabetes Correct Answer -
delated surfactant (soapy) from excess glucose
DKA Correct Answer - metabolic acidosis
--> ketones
T1DM
>250
kussmaul respirations --> lungs compensate, breathing fast
fruity breath
non ketosis Correct Answer - no acidosis!
T2DM
>600
IV insulin --> decreased WHAT Correct Answer -
HYPOGLYCEMIA
HYPOKALEMIA
fetal macrosomia Correct Answer - >4000 g
GDM --> higher risk of Correct Answer - UTI
poly
abruption
PPH
pre-e (glucose sticky! inhibits flow)
why does polyuria occur Correct Answer - glucose particles
make blood hypertonic and pulls volume into vascular space
why poly with maternal hyperglycemia Correct Answer - fetus
has developed polyuria as well
, when to screen for GDM Correct Answer - 24-28 weeks
or earlier if risk factors
1 hr GTT Correct Answer - 50 g load oral glucose
<140 --> greater? = 3 hr GTT
3 hr GTT Correct Answer - 100 g load oral glucose
fasting <95
1 hr <180
2 hr <155
3 hr <140
2 abnormal values = GDM
types of insulin needs during preg/PP Correct Answer - 1st tri
= decreased
2nd/3rd tri and labor = increased (more placental mass)
PP/lactation = decreased
--> breastfeeding decreases need for insulin
normal fasting BS Correct Answer - 60-90
PC BS Correct Answer - 1 hr <140
2 hr <120
normal A1C level Correct Answer - <6.4%
BS levels in labor Correct Answer - <120
higher? risk goes up for hypoglycemia for baby
metformin dosage Correct Answer - 500 - 1000 mg
take with food
