Question Answer
Ketones in Alcoholicsalcoholic ketones = beta-hydroxybutyrate which is not really detected in serum ketones, so there will be an anion gap but ketones won't be detected, DKA ketones (acetoacetate) are detected

formulas and criteria

Question Answer
Winter's1.5(bicarb) +8 +/- 2 = expected pCO2
Lights criteriafor effusion v transudate .5 .6 .7 -> pfluid/serum protein, pfluid/serum LDH, pfluid > 2/3 upper normal - any 1 indicates exudate
