Answer #1

a. Given data

Volume of solution = 750 mL

Flow rate = 85 mL/hr

The formula for drug calculation is

Volume (mL) = mL/ hr

Time (hr)

750 mL / Time = 85 mL/ hr

Time (hr) = 750 / 85=8.82

8.82 x 60 = 529.2

Time in hours is 8.82 hrs or 8 hours and 49 minutes

Time in minutes is 529 minutes

b. Given data

Desired dose ( dose ordered) = 225 mg tid or 225x3 = 675 mg/day

Recomended dose range = 10 mg/kg/day to 12.5 mg/ kg/per

Patient weight = 262 ibs = 119 kg

The recommended daily dose is (10x119) 1190mg to (12.5 x 119) 1487mg

The daily dose ordered is 675 mg / day ( less than the recomended range)
