to be considered bacterial sinusitis symptoms have to be 10+ days long. you would treat with amoxicillin (not sulfas). you can also have bacterial sinusitis with 3+ days of clinical symptoms + fever. This patient has had 4 days of symptoms and is afebrile- assume viral sinusitis for now and give symptomatic relief

okay soooo 40 participants is too low of a sample size- but 80 back in the new B-adrenergic drug vs. albuterol question was fine? is there like a magic sample number that is considered large enough?

beans123 I read this question as they didnt find the difference significant (and maybe there really is significance) ie a type II error and the way to not have a type two error is to increase the power/ie increase the sample size +1

lilyo Cholestasis will present with elevated conjugated bilirubin, Alkaline phosphatase, GGT. Depending on the cause for cholestasis it can present with pale stools and dark urine. This patient has cholestasis due to choledocolithiasis. Look at FA 2019 page 390. +

sars From what I understand, this could be acute cholangitis (inflammation of the bile duct-charcot triad-hypotension, RUQ pain, jaundice). Biggest risk factor for this is choledocholithiasis. Damage to bile ducts releases ALP and GGT. Thanks +1

you could also have used the loading dose equation (because they gave you loading dose and told you it was IV) LD= (Vd x Cp)/ F if you freak out at converting units like I do

Patient with history of breast cancer presents with progressive shortness of breath with elevated JVP, hypotension, pulsus paradoxus (drop in BP by at least 10 mm Hg on inspiration), enlarged heart on CXR and decreased voltage on ECG, most consistent with cardiac tamponade (likely secondary to cancer recurrence and metastasis to the pericardium)

lm4 or prior treatment with radiation caused fibrosis of pericardium --> constrictive pericarditis --> cardiac tamponade +5

jlbae This is the way. +

notyasupreme Doesn't tamponade not cause pulmonary edema / crackles since it's usually right sided heart failure? I picked it anyways, but remember a UWorld question about that vs. AR +
