leading zero if it applies. 10 mg/ 5 mL = 20 mg/ X mL
Do not use a trailing zero.) X mL = 10 mL
Step 7: Round if necessary.
Step 8: Determine whether the amount to administer
makes sense. If there are 10 mg/5 mL and the
prescription reads 20 mg, it makes sense to administer
10 mL. The nurse should administer codeine oral
solution 10 mL PO every 6 hr PRN pain.

Answer: 2 mL
Follow these steps for the Ratio and Proportion
method of calculation:
Step 1: What is the unit of measurement the nurse
should calculate? mg
Step 2: Set up an equation and solve for X.
X = Dose per kg × Client's weight in kg
X mg = 4 mg/kg × 60 kg
X mg = 240 mg
A nurse is preparing to
The dose is divided into three equal doses; therefore,

Do not use a trailing zero.)
Step 8: Set up an equation and solve for X.
Have/Quantity = Desired/X
40 mg/1 mL = 80 mg/X mL
X mL = 2 mL
Step 9: Round if necessary.
Step 10: Determine whether the amount to administer
makes sense. If there are 40 mg/mL and the
prescription reads 4 mg/kg/day divided in three equal
doses, it makes sense to administer 2 mL. The nurse
should administer tobramycin 2 mL IM per dose.
