okay but like the bnf says 15-20mg/kg, so if the question was really asking for the minimum volume, wont we be using the 15mg/kg values instead?

I understand what you are saying, but you are being told in this question that they are being given the 20mg/kg dose so you should use those values

Dose = 50 kg x 20 mg = 1000mg
Since maximum concentration is 5 mg/mL, minimum volume is 1000/5 = 200 mL

mL
An 84-year-old woman with a history of poorly controlled type 2 diabetes is admitted to the Vascular ward for treatment of a new diabetic foot infection. The resulting microbiology from her wound swab is only sensitive to Vancomycin. She weighs 50kg.


Prior to administration, Vancomycin needs to be diluted with sodium chloride 0.9% to a concentration that does not exceed 5 mg/mL.

What is the minimum volume (mL) to which each dose of Vancomycin (20 mg/kg) should be diluted?
