# Answer on Other Math Question for Katie

Question #15478

You receive a prescription for a drug to be given in a dose of 5 mg/m2. Calculate the dose of the drug for a patient with a BSA of 1.25m2. Solve the problem using both ratio and proportion and dimensional analysis.

Expert's answer

a) using ratio and proportion analysis:

5 / 1 = x / 1.25

x = 5 * 1.25 =

6.25 mg

b) using dimensional analysis: [x] = [ (mg/m2) * m2 ] = [mg]

5 / 1 = x / 1.25

x = 5 * 1.25 =

6.25 mg

b) using dimensional analysis: [x] = [ (mg/m2) * m2 ] = [mg]
