I think the distribution half-life and elimination half-life was saying that by the time you checked, it had fully distributed (10 half-lifes) and had not been cleared yet (super long half-life)
1000ug= 1mg and 1g=1000000ug
so then 4ug/ml * 1g/ 1000000ug= 0.000004 g/ml
0.000004g/ml * 1000ml/L= 0.004 g/L
80mg*1g/1000mg= 0.08 g
vd= 0.08g/ 0.04g/l =20L
Or, like a normal human, convert 4ug/mL into mg/L ... which is 4 mg/L. 80mg/4mg/L is 20L.
I hate NBME... I thought these stupid conversions were over after undergrad. Nope.
alcoholic in the hx should point you towards avascular necrosis when there is an “atraumatic” complaint
this kid has chronic pyelonephritis due to recurrent UTIs (VUR/hydronephrosis is a risk factor). And -itis = inflammation. That was my take on it.
