UWorld All Qs Flashcards
(132 cards)
Postpartum (months later), enlarged uterus, irregular vaginal bleeding, pulmonary symptoms, multiple infiltrates on cxr, dx?
Choriocarcinoma (metastatic GTD can occur after molar preg, normal preg, or SAB), dx w/ quantitative beta-hCG
Acute onset abdl pain ddx??
GI (PUD, appe, bowel obstruction/perforation), GU (kidney stone, ectopic preg, ovarian torsion, PID), vascular (bowel ischemia), MSK
Palpable breast mass on exam (irregardless of size), first step?
> 30yo = mammography (+/- US, then core prn). <30yo = US (+/- mammography, then needle aspiration for simple cyst, vs image guided bx for complex cyst aka solid mass)
Acute breast erythema, warmth, pain, and edema w/ peau d’orange (diffuse many dimpling), dx, next step
Inflammatory breast carcinoma, mammogram US and bx
Benign breast diseases (5)
Breast cyst, fibrocystic changes, fibroadenoma, fat necrosis (post-trauma/sex, firm irregular mass, ecchymosis, and skin/nipple retraction *hyperechoic mass, foamy macrophages, fat globules, excise and return to nrml routine screen)
Eclampsia, seizure, violent muscle contractions leading to what? Shoulder held in adduction and internal rotation?
Posterior shoulder dislocation, tx is closed reduction
Indications for endometrial bx (broken down into three age groups)
> 45: AUB or post-menopausal bleeding to r/o endometrial hyperplasia/cancer
<45: AUB and unopposed estrogen, obesity, anovulation (despite stripe of less than 4mm which is the cut off for postmenopausal women, a small stripe means nothing in premenopausal), failed medical mgmt, or lynch syndrome (HNPCC)
HTN in pregnancy
The first-line agents for management of essential hypertension during pregnancy are labetalol and methyldopa. Calcium channel blockers and hydralazine are acceptable alternate therapies. Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers arecontraindicated in pregnancy
Immediate postpartum or during delivery, cardiogenic shock, hypoxemic respiratory failure, DIC w/ generalized purpuric rash and bleeding from line site (coagulopathy), coma/seizures, dx and tx and risk factors?
Amniotic fluid embolism, tx w/ intubation/vent support +/- transfusion, risk factors = advanced maternal age, G5 or >, placenta previa/abruption, pre-E
Loss of fetal station, diminishing contractions, and palpable fetal parts
Uterine rupture
Adverse effect of tamoxifen (SERM)
Endometrial hyperplasia and carcinoma (good for breast bad for uterus)
Causes of hyperandrogenism in pregnancy (3 masses)
Luteoma (benign), thecal luteum cyst (benign), krukenberg tumor (met from GI cancer). All have some risk of fetal infertility virilization
Neonatal thyrotoxicosis (levothyroxine or antibody)?
Antibodies cross placenta -> s/s warm, tachy, irritable, low birth weight. Dx maternal anti-TSH receptor antibodies (can cross placenta). Self-resolving w/ disappearance of maternal antibody, symptomatically tx w/ methimazole and beta blocker
Hyperandrogenism (elevated DHEA, testosterone), oligomenorrhea (irregular >32 day cycle menses), hirsutism, elevated 17-OHP, normal electrolytes, dx?
Non-classic CAH (note normal lytes d/t spectrum of 21-hydroxylase def resulting in some aldo/cortisol and elevated 17-OHP), if elevated 17-OHP = not PCOS
S/s of placental abruption?
Vaginal bleeding, distended and TENDER uterus, and fetal tracing abnormalities
Placenta previa s/s, risk factors, mgmt
Risk = multiparity, SMOKING, previous uterine sx. Look for PAINLESS antepartum vaginal bleeding, nrml tracing, avoid digital vaginal exam or intercourse
Sudden painful onset vaginal bleeding, abdl/back pain, high freq contractions, hypertonic/tender uterus, dx and risk factors
Placental abruption! Risks = maternal HTN/pre-E, abdl trauma, prior abruption, COCAINE (back pain comes from blood pooling aka retroplacental bleeding btw placenta and uterine decidua
Vaginal and/or intra-abdominal bleeding, pain, fetal distress/demise, look for no presenting fetal parts vaginally and abdominally palpable detal parts at the rupture site, dx?
Uterine rupture
Blunt abdl trauma to pregnant mother, dx? Mgmt?
Placenta abruptio (this is the 3rd card), aggressive IV fluids and left lateral decub to displace uterus off vessels (tranfuse if persistent bleeding and hypotension unresponsive to fluids)
Mgmt of intrauterine fetal demise (death >20 wks gestation before labor)
20-23 weeks = D&E or vaginal delivery
24 weeks = vaginal delivery (C-section by maternal choice if hx of prior classical C-section - thereby preventing TOLAC essentially)
Magnesium in pregnancy indications/
Prevention of eclamptic seizures and decreases risk for cerebral palsy (neuroprotection). Signs of Mg toxicity - loss of DTRs, respiratory depression (labored effort dec resp rate), cardiac dysarythmia. Monitor urine output - since MG is cleared renally
HTN during pregnancy w/ edema, joint pain, malar rash, UA w/ proteinuria and RBC casts, dx?
SLE complicated by nephritis, ddx compared to pre-E look for decreased complement levels and inc ANA titers and usual SLE symptoms eg joint pain, malar rash
Elevated AFP vs dec AFP indications
Elevated = neural tube defects, ventral wall defects (omphalocele, gastroschisis), and multiple gestation (check fundal height correlation). Decreased = aneuploidies (trisomy 18/21)
Prenatal screening: non-diag vs diag
Non-diag (screening) = cell-free, tri-screen, quad-screen
CVS (before 15wks), amniocentesis (after 15wks); note give Rho-gam for RH-
