how can dig cause arrhytmias
fucks with low k
how does dig change calcium
more intracellular (so low serum calcium)

DI changes sodium how
high sodium
how do you diagnose salt losing nephropathy
low sodium, urine sodium >20
name 3 causes of salt losing nephropathy
ATN, diuretics, low aldosterone
urine spec and serum osm in DI
spec LOW (<1.006) and serum osm HIGH (>290)
