25
describe a 3-hour glucose challenge test?
you give 100-gram glucose load given to a patient i the morning who has fasted over night for at least 8 hours you then check serum glucose levels
26
what serum glucose levels for the 3-hour glucose challenge test indicate diabetes?
1. fasting greater than 95 2. 1 hour 180 or above 3. two hours 155 and above 4. 3 hours 140 and above

daily in the morning after fasting overnight and after each meal.

less than 95
30
What types of insulin is recommended for gestation diabetes?
NPH/regular 2/3 in the am 1/3 in pm
31
What PO form of diabetic medication can be used for preggos?
Glyburide because it doesnt cross the placenta but it does have a higher risk of preeclampsia
32
What do we want the serum glucose level to be at 2hour post prandial?
Less than 140 indicates good glucose control
33
What do you need to do weekly if the preggo needs to be on insulin?
need to have weekly fetal heart rate monitoring
34
What are some signs that someone is having a molar pregnancy?
ßHCG higher than expected, size-date discrepancy, hyperemesis
35
What is another name for a benign molar pregnancy?
hydatidiform moles
36
If you have a huge value for B-hcg and see a grape-like mass or snow-storm on transvaginal ultrasound do you think it is a complete or incomplete mole?
complete
37
what type of cancer can develop in pregnancy related to molar pregnancy?
Choriocarcinoma
38
What B-Hcg value is diagnostic of molar pregnancy?
HCG > 100,000
39
What form of imaging is the go to for dx molar pregnancy?
transvaginal ultrasound
40
How is the diagnoses of invasive moles/choriocarcinoma made?
1. when HCG levels plateau, meaning they remain within 10% of the previous result, over a three week period, 2. or when HCG levels increase more than 10% across three values recorded over two weeks, 3. or when there is still detectable serum HCG up to 6 months after evacuation of a molar pregnancy
41
What is the workup for persistent mole and choriocarcinoma?
1. CXR | 2. Head/abdomen and pelvis CT /contrast
42
Describe the stages of the tumor involved in persistent mole and choriocarcinoma?
Stage I tumors are confined to the uterus, and there are no metastases Stage II tumors extend to the fallopian tubes, the ovaries, or the vagina Stage III tumors have lung metastases, regardless of genital structure involvement Stage IV tumors have metastases in any organs other than the lungs or the genital structures
43
What is the treatment for complete and incomplete mole?
uterine evacuation via suction curettage
44
What lab value should you follow up on after a uterine evacuation via suction curettage for a complete or incomplete mole?
measure serum HCG weekly, until it’s undetectable for three consecutive weeks, and then once a month for 6 months
45
Tx for choriocarcinoma?
resect, methotrexate, chemotherapy based on the score. A score between 0 and 6 means low risk, so treatment relies on a single chemotherapeutic agent like methotrexate A score higher than 6 means high risk, and combination chemotherapy regimen like EMA-CO Remission is defined as three consecutive undetectable HCG levels during weekly monitoring
46
describe what an incompetent cervix is?
spontaneous, premature dilation or shortening of the cervix during the second or early third trimester (up to 28 weeks)
47
What would you see on PE of the cervix in someone with incompetent cervix?
cervical dilation >2cm | Less than 25mm at or before 24 weeks

a common cervical length for someone with incompetent cervix is what?
length < 25 mm before 24 wks, normally a cervix will be at least 30mm
52
What is the tx for incompetent cervix?
cervical cerclage placed at 12-16 weeks and removed at 36-38 weeks

it is made clinically, ultrasound is minimally useful but is usually ordered
57
what might an ultrasound show during placenta abruption?
retroplacental blood collection

1. complete 2. Partial 3. Marginal 4. Low-lying 5. Vasa previa
61
Describe the different types of placenta previa?
Complete- placenta completely covers the internal os Partial- only covers a portion of the os Marginal- edge of the placenta reaches the margin of the os low-lying- implanted in the lower uterine segment in close proximity but not extending to the internal OS. Vasa previa- Fetal vessel may lie over the cervix

1. delivery at 34-36 weeks | 2. Magnesium sulfate
72
If BP is 180/110 in a preggo what BP med should you give?
hydralizine
73
If patient meets all the requirements for preeclampsia and also has a seizure or coma what do they have?
eclampsia
74
Gestational hypertension is defined as?
BP >150/90 after 20 weeks into the pregnancy that resolves 12 weeks postpartum
75
Will you have proteinuria in gestational hypertension?
NO just elevated BP
76
Chronis hypertension in a preggo is defined as what?
BP >140/90 before 20 weeks gestation that resolves 6 weeks postpartum
77
How often should you monitor chronic hypertension?
every 2-4 weeks until weeks 34-36 then you should monitor it weekly.
78
What is the drug of choice in severe chronic hypertension?
Alpha Methyldopa is the drug of choice, avoid ACEI and diuretics, labetalol or nifedipine are safe alternatives

If mom is RH (-) and baby is Rh (+) can mom potentially kill baby?
yes mom may develop antibodies against babies blood.
80
