-small frequent meals
-avoidance of triggers
-ginger capsules
-P6 accupressure
SMFMs most updated definition of fetal growth restriction

You have a patient with significant N/v of pregnancy resistant to non pharmacologic interventions as well as vitamin B6 + doxylamine. According to acog - what should be your next step?
Dimenhydrinate
Diphenhydramine
Prochlorperazine
Promethazine
Stillbirth rate in pregnancies affected by growth restriction
1.5%
expected increase in plt count with each unit of plts transfused
7500mm3/U
ACOGs recommended use of abx for suspected intraamniotic infection postpartum (in the absence of overwhelming sepsis...)
Data suggest none needed postpartum after vag delivery, one additional dose after cesarean
-important to assess constellation of risk factors
You discover your patient has a plt count of 50K @ 28 weeks. Once ruling out preeclampsia, what is the most likely etiology?
ITP
GI tract site at which most dietary iron is absorbed
What is duodenum
Per our screening protocol, the range of cervical length measurements within which an FFN may be helpful
20-29mm
2 acceptable regimens for ratio of products transfused in massive hemorrhage (Prbc:ffp:plt)
Either 1:1:1 (rarely done in practice), or 1:2:4
Primary outcome of the ALPS trial
Administration of BMZ in the late preterm period significantly reduced neonatal respiratory complications (11.6% vs 14.4% in palcebo)
You have a patient with ITP and platelet count of 30K found to be in active labor in breech presentation, requiring cesarean delivery. What is the target plt level for a patient underroing major abdominal surgery
50K
5 common vitamin deficiencies in pts with hx of Bariatric surgery
Fe, B12, folate, Vitamin D, Calcium
Gestational age range at which SMFM recommends delivery in the setting of fetal growth restriction with Absent end diastolic flow on UA doppler
33-34wks
What class of topical hemostatic agents is contraindicated in pts w/ severe coagulopathy
Physical agents - surgicel, arista, gelfoam
Because they provide a substrate to form a matrix at the site of bleeding which activates extrinsic clotting cascade, serves as scaffold for clot formation require intact coagulation cascade to function
In pts with a BMI >30, what post-cesarean regimen has been shown to reduce SSI
Keflex and Flagyl - both 500 q8h x 48 hrs
chromosomal locations of the alpha and beta globin genes
b- short arm of chromosome 11
In pts requiring steroids for hyperemesis, what is the ACOG recommended regimen? prior to what GA should steroids be avoided and why?
Methylprednisolone 16mg q8h x 3 days (PO or IV)
10 wks, risk of oral clefting
4 subsets of patients in which prophylaxis against infectious endocarditis is indicated
-Pts with prosthetic heart valves, or prosthetic components
-pts with hx of infectious endocarditis
-pts with hx of CHD and: incomplete repair or repaired CHD with residual defects (valvular disease)
-pts w/ heart transplant w/ valve regurg due to structurally abnormal valve
You have a patient with 3 prior cesarean deliveries who is pregnant again and found to have a placenta previa @ 20 weeks - what is the chance this pt also has an accreta?
61%
ACOG Criteria for suspected intraamniotic infection
Maternal intrapartum fever plus one or more:
-purulent cervical discharge
-leukocytosis
-fetal tachycardia
