Follow these steps for the Ratio and Proportion method of calculation:
ji ji ji ji ji ji ji ji ji ji
Step 1: What is the unit of measurement the nurse should calculate? mL
ji ji ji ji ji ji ji ji ji ji ji ji
Step 2: What is the dose the nurse should administer? Dose to administer = Desired 20

Step 3: What is the dose available? Dose available = Have 10 mg
ji ji ji ji ji ji ji ji ji ji ji ji
Step 4: Should the nurse convert the units of measurement? No
ji ji ji ji ji ji ji ji ji ji
Step 5: What is the quantity of the dose available? 5 mL
ji ji ji ji ji ji ji ji ji ji ji
Step 6: Set up an equation and solve for X.
ji ji ji ji ji ji ji ji ji
Have/Quantity = Desired/X ji ji
10 mg/ 5 mL = 20 mg/ X mL
ji ji ji ji ji ji ji ji
X mL = 10 mL
ji ji ji ji
Step 7: Round if necessary.

Step 8: Determine whether the amount to administer makes sense. If there are 10 mg/5
ji ji ji ji ji ji ji ji ji ji ji ji ji ji

Step 3: What is the dose available? Dose available = Have 1 mg
ji ji ji ji ji ji ji ji ji ji ji ji
Step 4: Should the nurse convert the units of measurement? Yes (mcg does not equal mg)
ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji
1,000 mcg/1 mg = 2,000 mcg/X mg
ji ji ji ji ji ji
X mg = 2 mg
ji ji ji ji
Step 5: Round if necessary.

Step 6: Determine whether the amount to administer makes sense. If the prescription
ji ji ji ji ji ji ji ji ji ji ji ji
reads 2,000 mcg and 1,000 mcg equals 1 mg, it makes sense to administer 2 mg. The

Follow these steps for the Ratio and Proportion method of calculation:
ji ji ji ji ji ji ji ji ji ji
Step 1: What is the unit of measurement the nurse should calculate? mg
ji ji ji ji ji ji ji ji ji ji ji ji
, Step 2: Set up an equation and solve for X.
ji ji ji ji ji ji ji ji ji
X = Dose per kg × Client's weight in kg
ji ji ji ji ji ji ji ji ji
X mg = 4 mg/kg × 60 kg
ji ji ji ji ji ji ji
X mg = 240 mg
ji ji ji ji
The dose is divided into three equal doses; therefore, divide X by 3.
ji ji ji ji ji ji ji ji ji ji ji ji
240 mg = 80 mg3 ji ji ji ji
Step 3: What is the unit of measurement the nurse should calculate? mL

Step 6: Should the nurse convert the units of measurement? No
ji ji ji ji ji ji ji ji ji ji
Step 7: What is the quantity of the dose available? 1 mL
ji ji ji ji ji ji ji ji ji ji ji
Step 8: Set up an equation and solve for X.
ji ji ji ji ji ji ji ji ji
Have/Quantity = Desired/X ji ji
40 mg/1 mL = 80 mg/X mL
ji ji ji ji ji ji
X mL = 2 mL

Step 10: Determine whether the amount to administer makes sense. If there are 40
ji ji ji ji ji ji ji ji ji ji ji ji ji
mg/mL and the prescription reads 4 mg/kg/day divided in three equal doses, it makes
ji ji ji ji ji ji ji ji ji ji ji ji ji ji
sense to administer 2 mL. The nurse should administer tobramycin 2 mL IM per dose.
