25
Q

What is serum inhibin B measured for?

A

determination of ovulatory reserve

26
Q

Causes of symmetric IUGR

A

body/head proportionately small due to FETAL factors: chr abn, congen anom, TORCH

27
Q

Causes of asymmetric IUGR

A

weight due to MATERNAL factors:

HTN, pre-e, uterine abnormalities, smoking*, APLA

28
Q

best method to estimate fetal weight in suspected IUGR

A

abdominal circumference

29
Q

blood at the urethral meatus, inability to void, high-riding prostate on DRE? possible other findings? POA?

A

posterior urethral injury

Dx = retrograde urethrogram, NOT a foley

30

perineal or scrotal hematoma, think

A

pelvic fracture

31
Q

Dense deposits that stain C3? MoA?

MPGN –> persistent activation of alternative complement pathway

32
Q

HIV patient with esophagitis showing multiple well-circumscribed, small volcano-like ulcers, biopsy showing ballooning degeneration and eosinophilic intranuclear inclusions? Tx?

A

HSV, tx acyclovir

33
Q

HIV patient w/ esophagitis showing large, shallow, superficial ulcers. biopsy showing intranuclear AND intracytoplasmic inclusions? Tx?

A

CMV, Tx ganciclovir

34
Q

Immunosuppressant causing diarrhea, leukopenia and hepatotoxicity

A

azothioprine

35
Q

Variable decels? Tx?

A 
cord compression (low AFI or nuchal cord)
Tx = O2, change maternal position, stop oxytocin
36
Q

Effect of pregnancy on GFR, RPF, BUN and Cr

A

increased GFR and renal plasma flow causes decreased BUN and Cr

37
Q

Bounding pulses, widened pulse pressure

A

AR –> bound pulse is due to increased SV from previously regurgitated volume

38
Q

50yo with dysmenorrhea, menorrhagia, symmetrically enlarged uterus? ddx?

A

MCC adenomyosis

ddx = leiomyoma (similar but IRREGULAR shape on US)

mild = dicloxicillin

severe (systemic sx) = IV nafcillin or cefazolin

A

do colposcopy; if normal –> repeat + bx after preg.

if colpo suggests invasive CA, excise

42
Q

PCOS, Tx and MoA?

A

for infertility, tx = clomiphene citrate (E2 analog enhances GnRH release –> ovulation)
Metformin helps improve ovulation

A

test at 35-37wks vaginal and rectal swab

if +, tx = PCN or ampicillin at delivery
