tx of Asx bacteriuria in pregnant pt (even if culture was done at prenatal visit and this is a later visit)
Abx now: cephalexin, amoxi-clav, or fosfomycin
why might a patient still have cost-sharing expenses above their deductible?
They have not met their plan’s annual out-of-pocket maximum (includes deductible, copays, coinsurance)
cause of marked increase in Cr after ACE-i is started in kidney transplant pt

pain, red, variable visual loss, constricted and irregular pupil; leukocytes in ant. segment
presentation of infectious keratitis
severe photophobia and difficulty in keeping bad eye open; penlight shows corneal opacity or infiltrate
what to do if pt had mono, gets better, but LAP persists on one side or exists somewhere besides posterior cervical nodes
send pt to get LN biopsy; might be lymphoma
which patients with asymptomatic bacteriuria need treatment
pregnant, undergoing urologic procedures, or within 3 months of renal transplantation
reversal of warfarin therapy
prothrombin complex concentrate 1st, then IV vit. K; fresh frozen plasma only if PCC unavailable

how much of a washout period is needed between SSRI’s and MAOI’s
most - 14 days
fluoxetine - 5 weeks

discontinue all serotonergic meds; supportive care and sedate w/ benzo
presentation of diffuse esophageal spasm
CP and dysphagia to solids and liquids
what testing shows for diffuse esophageal spasm

tx of diffuse esophageal spasm
CCB
TB presentation in patients with low CD4 counts
lobar, pleural, or disseminated siease
fluid characteristics of a TB pleural effusion
lymphocytic and exudative with an elevated ADA level
what is needed to confirm dx of TB pleural effusion
pleural biopsy (smear is often negative)
mgt of DKA: IVF
NS; add dextrose when G <200
mgt of DKA: insulin
start IV insulin (unless K low); switch to SQ when able to eat, G <200, AG <12, and serum bicarb >15; overlap SQ and IV by 1-2 hrs
effect modification
when magnitude of effect of independent variable (intervention) on dependent variable (outcome) varies depending on level of a third variable (effect modifier); need to do stratified analyses for each level of the effect modifier
confounding bias
when extraneous variable associated with both exposure and outcome obscures the associate between exposure and outcome; stratification does not change direction of effect
tx of acute gout
NSAIDs or colchicine or steroids, depending on pt
acute stress disorder versus PTSD
ASD: sxs 3d-1mo
