A nurse is preparing to administer tobramycin 4 mg/kg/day IM
divided in three equal doses to a patient who weighs 60 kg.
Available is tobramycin 40 mg/mL. How many mL should the
nurse administer per dose?
(Round to the nearest whole number. Use a leading zero if it
applies. Do not use a trailing zero.) - THE CORRECT ANSWER-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
,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 meperidine 75 mg IM stat.
Available is meperidine injection 100 mg/mL. How many mL
should the nurse administer?
(Round answer to nearest hundredth. Use a leading zero if it
applies. Do not use a trailing zero.) - THE CORRECT ANSWER-Answer:
0.75 mL
, Follow these steps for the Ratio and Proportion method of
calculation:
Step 1: What is the unit of measurement the nurse should
calculate? mL
Step 2: What is the dose the nurse should administer? Dose to
administer = Desired 75 mg
Step 3: What is the dose available? Dose available = Have 100
mg
Step 4: Should the nurse convert the units of measurement? No
Step 5: What is the quantity of the dose available? 1 mL
Step 6: Set up an equation and solve for X.
Have/Quantity = Desired/X
100 mg / 1mL =75 mg/ X mL
X mL = 0.75 mL
Step 7: Round if necessary.
Step 8: Determine whether the amount to administer makes
sense. If there are 100 mg/mL and the prescription reads 75
mg, it makes sense to administer 0.75 mL. The nurse should
administer meperidine 0.75 mL IM.
A nurse is preparing to administer famotidine 40 mg PO at
bedtime. Available is famotidine 20 mg/tablet. How many
tablets should the nurse administer?
(Round answer to nearest whole number. Use a leading zero if
it applies. Do not use a trailing zero.) - THE CORRECT ANSWER-
Answer: 2 tablets
