IV Dosage Calculation
- 0Jan 30, '13 by my4helpersDoes anyone have an easy way to do these type of problems? Our test is next week and I am just so confused by these; we also need to get 100% or we fail. We had one dosage calculation test last week over oral and I can do those, it's just the IV ones that are confusing. Our instructors did not show us how either.

if weight is given to you in pounds convert it to kg by dividing pt. weight in pounds by 2.2 and that will give you kg
So lets say for example 5mg/kg/day pt. weight is 130lb
130/2.2 = 59 kg is the pt's weight
5mg/kg/day x 59kg = 295mg/day (the kg's cancel out so you are left with mg and day)
Infusion rates you would first figure out pt weight in kg. then figure out how many mg they are to receive, then figure out how many
mL would equal that amount and last figure out how many mL you would have to infuse every hour to get it all in within the allotted time frame.
I hope I didn't confuse you.
Remember your flow rate will always be mL/hour
