F to C formula
C = (F-32)(5/9)
C to F Formula
F = (C * 9/5) + 32
Rules of Estimation/Writing
- PUT UNITS
-estimate to the tenth, unless under 1mL, then its hundredths place
-Drop must be rounded to a whole number
Formulas to Know (non-IV)
- Desire (the order/Have )* quantity = Answer
ex: Order 4 mg q 6 hours; supply 2 mg/1mL –> 4mg/2mg times 1 mL = 2 mL - Ratio Proportion
> Dosage on hand/Amount on Hand times Dosage Desired/X (amount desired)
Manual Drip (gtts) Rate formula
Total Volume/Minutes * C (gtts factor) = X
Setting an IV Pump (mL/hr) Formula
Total Volume/Hour = X
