UWorld_8.02 Flashcards
Colon cancer screening
- @ >50yo
- if 1ST DEG. RELATIVE: @ 40yo or 10y before dx
Tricuspid valve atresia presentation/findings
- cyanotic heart disease w/hypoplastic R ventricle
- EKG: left axis deviation, peaked p waves
- CXR: decreased pulmonary markings
Total anamolous pulmonary venous return presentation/findinsgs
- all 4 pulm. veins fail to connect to L. atrium
- R atrial enlargement
- ECG: R ventricular hypertrophy, R axis deviation
- CXR: increased pulm. markings
Management of hyperCa
- severe ==> IV hydration + calcitonin, avoid loop diuretics if possible; long term = bisphosphonates
- moderate/mild ==> avoid thiazides/Li/volume depletion
Dx of HIT
- serotonin release assay
- start tx before confirmatory tests (stop hep & start thrombin inhibitor)
Tx of frostbite
- rapid re-warming with warm water
- do not debride immediately; re-eval after re-warming
HIV-assoc. kidney disease
FSGS
Tx in PAD
- PAD = type of ASCVD ==>
- ASA + statin
CMV colitis ==> ?
bloody diarrhea @ HIV pt. w/CD4
Evaluation of diarrhea @ HIV patient
- stool test for ova/parasites
- c. diff antigen
- acid fast stain ==> cryptosporidium
Sporotrichosis vs. Poison ivy contact dermatitis
- contact dermatits ==> vesicular, erythematous rash
- sporotrichosis ==> ulcerating, pustular nodules
Ca/Phos in paget disease of bone
usually normal
Day care worker with joint pains ==> dx?
viral arthritis/parvovirus B19
normal LV ejection fraction
> 50%
Cervical mucus during menstrual cycle phases
- ovulatory = profuse, clear, thin, stretchy
- mid/late luteal = thicker, less stretchy
- follicular = thick, scant, acidic
Causes of infective endocarditis
-s. aureus
Laxative abuse presentation
- frequent, watery diarrhea ~10-20 BMs/day
- dx = biopsy w/dark brown discoloration + lymph follicles shining pale patches (melanosis coli)
Reversible cause of restrictive cardiomyopathy
hemochromatosis
Poor signs on ABG in asthma exacerbation
normal/elevated PaCO2
Causes/pathophysiology of NAFLD
insulin resistance + increased lipolysis, TG synth, hepatic uptake of FAs
Tx of trigeminal neuralgia
carbamazepine
Complicated parapneumonic effusion vs. empyema
- both = pH .6
- complicated = negative gram stain/culture
- empyema = positive gram stain/culture
biliary colic vs. acute cholecystitis pathophysiology
- biliary colic 2/2 increased intragallbladder pressure during contraction (after meal) against obstructed duct
- cholecystitis 2/2 inflamed/infected mucosa
SE of norepinephrine
vasospasm ==> necrosis @ digits, intestines, kidneys
