Why the FUCK did they not just give us a clearance of 0.1 if they're going to fuckin round it anyways...

in ur maths, why did u put 24h/1day and not 1day/24h? if the given Cl was 0.09L/hr/kg. I know it just is a math question, but i´d appreciate if someone could explain it.

Can anyone further explain this?! I could eliminate a few item choices and I guessed correctly, just need more information! Thanks

Patient has 5 yr h/o hep C, so it is chronic. Chronic inflammation is characterized by presence of lymphocytes & plasma cells while neutrophils is more characteristic of acute inflammation (Pathoma Ch. 2). AFP is within reference range so probably not HCC. Choice D, palisading lymphocytes & giant cells suggests granuloma which isn't typical of hep C.

Maintenance dose formula is (Css

Cltau)/F where Css is steady-state target plasma conc. of drug, Cl is clearance, tau is dosage interval & F is bioavailability.Neither dosage interval nor bioavailability is given, so ignoring those & plugging in the numbers (careful to convert units to mg/kg/day): (12 ug/mL * 1 mg/1000 ug) * (0.09 L/hr/kg * 1000 mL/1 L * 24 hr/1 day) = 25.92 mg/kg/day

...which isn't any of the answer choices listed. They must have rounded 0.09 L/hr/kg to 0.1 L/hr/kg, and doing so gives exactly 28.8 mg/kg/day (choice C)
