Medications
The recommended dosage of folic acid in a pregnant patient whose first child was born with spina bifida.
4mg/day. Supplementation should start >3 months prior to pregnancy and continue though at least 12 weeks gestation.
Signs/Symptoms include:
Uterine enlargement
"prune juice" vaginal discharge
Markedly elevated BHCG
No FHT/FM
Hyperemesis
Pre-eclampsia
Hydatidiform Mole
Abdominal trauma (MVA, abuse)
Vasospasm (HTN, Drug use (cocaine, meth)
Hyperstimulation of the uterus
What distance of the placenta from the cervical os defines low-lying placenta
<2cm
The HCG concentration peaks at around this gestational age, then starts to decline.
8-10 weeks gestation
Three HIGH-RISK factors that indicate the need for low-dose aspirin at 12 weeks gestation
History of Pre-Eclampsia
Multifetal gestation
Chronic Hypertension
Type 1 or Type 2 Diabetes
Renal disease
Autoimmune disease (lupus, antiphospholipid)
Three risk factors for placenta previa
Previous Placenta Previa
Previous Cesarean Birth
Multiple Gestation
Previous uterine surgery
Increased Parity
Advanced Maternal Age
Infertility treatment
Smoking
Cocaine Use
Male Fetus
Prior Uterine Artery Embolization
Endometriosis
Hx of Spab or Tab
The 5 components of a biophysical profile that are often combined with/or substituted for a non-stress test.
Fetal Heart Rate
Fetal Breathing
Fetal Tone
Fetal Movement
Amniotic Fluid Index (AFI)
Toxoplasmosis
Other (syphilis, varicella, Zika virus)
Rubella
Cytomegalovirus
Herpes Simplex virus
This vaccine is recommended between 32 and 36 weeks of pregnancy
This ultrasound finding is NOT diagnostic of pregnancy failure
A. Crown-rump length of <7mm and no heartbeat
B. Mean sac diameter of >25mm and no embryo.
C. Absence of embryo with heartbeat >2 weeks after a scan that showed a gestational sac without a yolk sac
D. Absence of embryo with a heartbeat >11 days after a scan that showed a gestational sac with yolk sac
A. Crown rump length of <7mm is suspicious for, but not diagnostic of pregnancy failure. CRL of >7mm is diagnostic of pregnancy failure.
This is the likely diagnosis when a patient, with no prior history of Syphilis, tests POSITIVE on a nontreponemal test (RPR/VDRL), but tests NEGATIVE on the treponemal test (FTA-ABS).
False positive. The test should be repeated in 2-4 weeks if there has been a recent high-risk exposure.
Three MODERATE risk factors that would indicate the need for low-dose aspirin if more than one of these risk factors are present.
Obesity (BMI>30)
Family history of Pre-Eclampsia
Sociodemographic characteristics (African-American, low socioeconomic status)
Women aged 35 years or older
Personal history factors (low birth weight, SGA, previous adverse pregnancy outcome, more than 10 year pregnancy interval
Nulliparity
The most frequent type of aneuploidy associated with the presence of a choroid plexus cyst
Trisomy 18. Cysts that are at least 2cm, and seen in two orthogonal planes, is particularly suspicious for aneuploidy and a formal high-risk anatomic survey should be performed.
