Question 1:
A nurse is preparing to administer cefazolin 250 mg IM to a client. Available is
cefazolin powder for injection 500 mg vial. The nurse reconstitutes the powder
with 2 mL of sterile water for a concentration of 225 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: 1.1
The nurse can determine the volume of cefazolin to administer based on the available
information:
1. Reconstituted concentration: The cefazolin is reconstituted to a concentration of225
mg/mL.
2. Dosage required: The nurse needs to administer 250 mg of cefazolin.
3. Volume calculation: We can use the following formula to find the volume
toadminister:
Volume (mL) = Dosage (mg) / Concentration (mg/mL)
Volume (mL) = 250 mg / 225 mg/mL
4. Rounding the answer: Round the answer to the nearest tenth of a milliliter.
Volume (mL) = 1.1 mL (rounded to one decimal place)
Therefore, the nurse should administer 1.1 mL of the reconstituted cefazolin solution.

Question 2:
A nurse is preparing to administer clindamycin 10 mg/kg/day PO in three
divided doses to a child who weighs 53 lb. Available is clindamycin oral solution
75 mg/5 mL. How many mL should the nurse administer per dose? (Round the
answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing
zero.)
Explanation
Correct Answer: 5.3
To calculate the correct dose of clindamycin, we need to follow these steps:
1. Convert pounds to kilograms:
53 lb * 0.4536 kg/lb = 24 kg
2. Calculate the daily dose in milligrams:
10 mg/kg/day * 24 kg = 240 mg/day
3. Calculate the dose per administration:
Since the medication is divided into three doses, divide the daily dose by
3: 240 mg/day / 3 = 80 mg/dose
4. Determine the volume needed from the available concentration:
80 mg * (5 mL / 75 mg) = 5.33 mL
Therefore, the nurse should administer 5.3 mL of clindamycin per dose.
Answer: 5.3 mL

Question 3:
A nurse is preparing to administer methylprednisolone acetate 60 mg IM weekly.
Available is methylprednisolone acetate suspension for injection 80 mg/mL.
How many mL should the nurse administer per dose? (Round the answer to the
nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Correct Answer: 0.75
1. Dosage and Concentration:
Methylprednisolone acetate dosage: 60 mg
Methylprednisolone acetate concentration: 80 mg/mL (available suspension)
2. Volume Calculation:
We can use the following formula to find the volume to administer:
Volume (mL) = Dosage (mg) / Concentration (mg/mL)
Volume (mL) = 60 mg / 80 mg/mL
3. Rounding the Answer:
Round the answer to the nearest hundredth of a milliliter.
