Question 1:
A nurse is preparing to administer morphine 0.2 mg/kg IM to a client who
weighs 99 lb. Available is morphine injection 10 mg/mL. How many mL should
the nurse administer? (Round the answer to the nearest tenth. Use a leading
zero if it applies. Do not use a trailing zero.)
Explanation
Correct Answer: 0.9
Identify the given information:
Dose of morphine: 0.2 mg/kg
Weight of the client: 99 lb
Concentration of morphine injection: 10 mg/mL
Convert the client's weight from pounds to kilograms:
1 lb ≈ 0.453592 kg
Calculate the total dose of morphine in mg:
Total dose = Dose/kg x Weight (kg)
Substitute the values:
Total dose = 0.2 mg/kg x 99 lb x (0.453592 kg/1 lb)
Total dose ≈ 8.99 mg
Calculate the volume of morphine injection to be administered:
Volume = Total dose (mg) / Concentration (mg/mL)
Substitute the values:
1/40

Volume = 8.99 mg / 10 mg/mL
Volume ≈ 0.899 mL
Round the answer to the nearest tenth:
Volume ≈ 0.9 mL

Question 2:
A nurse is preparing to administer digoxin 0.375 mg PO daily. Available is
digoxin elixir 0.05 mg/mL. How many mL should the nurse administer? (Round
the answer to the nearest tenth. Use a leading zero if it applies. Do not use a
trailing zero.)
Explanation
Correct Answer: 7.5
Identify the given information:
Dose of digoxin: 0.375 mg
Concentration of digoxin elixir: 0.05 mg/mL
Calculate the volume of digoxin elixir to be administered:
Volume = Dose (mg) / Concentration (mg/mL)

Question 3:
A nurse is preparing to administer insulin glargine to a child who has type 1
diabetes mellitus. The client is to receive 10 units subcutaneous once daily at
bedtime. Reading the label on the unopened vial, the nurse should determine
that the vial contains how many doses of this medication? (Round the answer
to the nearest whole number. Use a leading zero if it applies. Do not use a
trailing zero.)
Explanation
Correct Answer: 100
Step 1: Identify the given information:
Concentration of insulin glargine: 100 units/mL
Volume of the vial: 10 mL

Step 2: Calculate the total number of units in the vial:
Total units = Concentration (units/mL) x Volume (mL)
Step 3: Substitute the values:
Total units = 100 units/mL x 10
mL Step 4: Calculate the result:
Total units = 1000 units
Step 5: Calculate the number of doses:
Number of doses = Total units / Dose per dose
Step 6: Substitute the values:
Number of doses = 1000 units / 10 units/dose
Step 7: Calculate the result:
Number of doses = 100 doses
