A nurse is preparing to administer Answer: 10 mL
codeine 20 mg PO every 6 hr PRN
pain. Available is codeine oral Follow these steps for the Ratio and Proportion
solution 10 mg/ 5 mL. How many mL method of calculation:
should the nurse administer per Step 1: What is the unit of measurement the nurse
dose? should calculate? mL
Step 2: What is the dose the nurse should
(Round to the nearest whole administer? Dose to administer = Desired 20 mg
number. Use a leading zero if it Step 3: What is the dose available? Dose
applies. Do not use a trailing zero.) available = Have 10 mg
Step 4: Should the nurse convert the units of
measurement? No
Step 5: What is the quantity of the dose available?
5 mL
Step 6: Set up an equation and solve for X.
Have/Quantity = Desired/X
10 mg/ 5 mL = 20 mg/ X mL
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.
,A nurse is preparing to administer Answer: 2 mg
eszopiclone 2,000 mcg PO to a
client. How many mg should the Follow these steps for the Ratio and Proportion
nurse administer? method of calculation:
Step 1: What is the unit of measurement the nurse
(Round to the nearest whole should calculate? mg
number. Use a leading zero if it Step 2: What is the dose the nurse should
applies. Do not use a trailing zero.) administer? Dose to administer = Desired 2,000
mcg
Step 3: What is the dose available? Dose
available = Have 1 mg
Step 4: Should the nurse convert the units of
measurement? Yes (mcg does not equal mg)
1,000 mcg/1 mg = 2,000 mcg/X mg
X mg = 2 mg
Step 5: Round if necessary.
Step 6: Determine whether the amount to
administer makes sense. If the prescription reads
2,000 mcg and 1,000 mcg equals 1 mg, it makes
sense to administer 2 mg. The nurse should
administer eszopiclone 2 mg PO.
, A nurse is preparing to administer Answer: 2 mL
tobramycin 4 mg/kg/day IM
divided in three equal doses to a Follow these steps for the Ratio and Proportion
patient who weighs 60 kg. Available method of calculation:
is tobramycin 40 mg/mL. How many Step 1: What is the unit of measurement the nurse
mL should the nurse administer per should calculate? mg
dose? Step 2: Set up an equation and solve for X.
X = Dose per kg × Client's weight in kg
(Round to the nearest whole X mg = 4 mg/kg × 60 kg
number. Use a leading zero if it X mg = 240 mg
applies. Do not use a trailing zero.) The dose is divided into three equal doses;
therefore, divide X by 3.
240 mg = 80 mg3
Step 3: What is the unit of measurement the nurse
should calculate? mL
Step 4: What is the dose the nurse should
administer? Dose to administer = Desired 80 mg
Step 5: What is the dose available? Dose
available = Have 40 mg
Step 6: Should the nurse convert the units of
measurement? No
Step 7: What is the quantity of the dose available?
1 mL
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.

, A nurse is preparing to administer Answer: 2 mL
tobramycin 4 mg/kg/day IM
divided in three equal doses to a Follow these steps for the Ratio and Proportion
patient who weighs 60 kg. Available method of calculation:
is tobramycin 40 mg/mL. How many Step 1: What is the unit of measurement the nurse
mL should the nurse administer per should calculate? mg
dose? Step 2: Set up an equation and solve for X.
X = Dose per kg × Client's weight in kg
(Round to the nearest whole X mg = 4 mg/kg × 60 kg
number. Use a leading zero if it X mg = 240 mg
applies. Do not use a trailing zero.) The dose is divided into three equal doses;
therefore, divide X by 3.
240 mg = 80 mg3
Step 3: What is the unit of measurement the nurse
should calculate? mL
Step 4: What is the dose the nurse should
administer? Dose to administer = Desired 80 mg
Step 5: What is the dose available? Dose
available = Have 40 mg

Step 7: What is the quantity of the dose available?
1 mL
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
