A nurse is preparing to administer 750,000 units of procaine penicillin G
IM. Available is procaine penicillin G injection
600,000 units/mL. How many mL should the nurse administer per dose?
(Round answer to nearest tenth. Use a leading zero if it applies.
Do not use a trailing zero.) - THE CORRECT ANSWER-Answer: 1.3 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 750,000 units
Step 3: What is the dose available? Dose available = Have 600,000
units
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
600,000 units/1 mL = 750,000 units/X mL
X mL = 1.25 mL
Step 7: Round if necessary. 1.25 mL = 1.3 mL
,Step 8: Determine whether the amount to administer makes sense. If
there are 600,000 units/mL and the prescription reads 750,000 units, it
makes sense to administer 1.3 mL. The nurse should administer
procaine penicillin G 1.3 mL IM.
A nurse is preparing to administer lorazepam 0.05 mg/kg IM 2 hours
prior to surgery to a patient who weighs 138 lb. Available is lorazepam
injection 2 mg/mL. How many mL should the nurse administer?
(Round answer to nearest tenth. Use a leading zero if it applies.
Do not use a trailing zero.) - THE CORRECT ANSWER-Answer: 1.6 mL
Step 1: What is the unit of measurement the nurse should calculate? kg
Step 2: Set up an equation and solve for X.
2.2 lb/ 1 kg = Client's weight in lb/X kg
2.2 lb/1 kg = 138 lb/X kg
X kg = 62.727272 kg
Step 3: What is the unit of measurement the nurse should calculate? mg
Step 4: Set up an equation and solve for X.
X = Dose per kg × Client's weight in kg
X mg = 0.05 mg/kg × 62.727272 kg
X mg = 3.136363 mg
Step 5: What is the unit of measurement the nurse should calculate? mL
Step 6: What is the dose the nurse should administer? Dose to
administer = Desired 3.136363 mg
Step 7: What is the dose available? Dose available = Have 2 mg
Step 8: Should the nurse convert the units of measurement? No
Step 9: What is the quantity of the dose available? 1 mL Step 10:
Set up an equation and solve for X.
Have/Quantity = Desired/X
2 mg/ 1 mL = 3.136363 mg/X mL
, X mL = 1.568181 mL
Step 11: Round if necessary. 1.568181 mL = 1.6 mL
Step 12: Determine whether the amount to administer makes sense. If
there are 2 mg/mL and the prescription reads lorazepam 0.05 mg/kg, it
makes sense to administer 1.6 mL.
The nurse should administer lorazepam injection 1.6 mL IM.
A nurse is preparing to administer midazolam 0.07 mg/kg IM to a patient
who weighs 50 kg. Available is midazolam 5 mg/mL. How many mL
should the nurse administer?
(Round answer to nearest tenth. Use a leading zero if it applies.
Do not use a trailing zero.) - THE CORRECT ANSWER-Answer: 0.7 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 = 0.07 mg/kg × 50 kg
X mg = 3.5 mg
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 3.5 mg
Step 5: What is the dose available? Dose available = Have 5 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
5 mg/1 mL = 3.5 mg/ X mL
