Original Questions (1-26) with Enhanced Format
1. A nurse is preparing to administer dextrose 5% water (D5W) 250 mL IV to infuse over 2 hr.
The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole
number)
• A. 100 mL/hr
• B. 125 mL/hr
• C. 150 mL/hr
• D. 250 mL/hr
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ B. 125 mL/hr
Rationale: To find the flow rate in mL/hr, use the formula: Total Volume (mL) / Total Time (hr).
250 mL / 2 hr = 125 mL/hr. The other options are incorrect calculations.
,2. A nurse is preparing to administer cefazolin 250 mg IM to a client. Available is cefazolin
powder 500 mg vial. The nurse reconstitutes the powder adding 2 mL of sterile water to yield
a final concentration of cefazolin 225 mg/mL. How many mL should the nurse administer?
(Round to the nearest tenth)
• A. 1.0 mL
• B. 1.1 mL
• C. 1.2 mL
• D. 2.2 mL
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ B. 1.1 mL
Rationale: Use the formula: Desired Dose / Have x Quantity. The concentration is 225 mg/mL.
250 mg / 225 mg x 1 mL = 1.111... mL. Rounding to the nearest tenth gives 1.1 mL. Option D is
the volume for a 500 mg dose.
3. A nurse is preparing to administer ribavirin 600 mg P.O. every 12 hr. Available is ribavirin
200 mg/tablet. How many tablets should the nurse administer per dose? (Round to the
nearest whole number)
• A. 1 tablet
• B. 2 tablets
• C. 3 tablets
• D. 4 tablets
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ C. 3 tablets
Rationale: Use the formula: Desired Dose / Have x Quantity. 600 mg / 200 mg x 1 tablet = 3
tablets. The other options are incorrect.
4. A nurse is preparing to administer furosemide 20 mg IM. Available is furosemide injection
10 mg/mL. How many mL should the nurse administer? (Round to the nearest whole number)

Options A, B, and D are incorrect calculations.
5. A nurse is preparing to administer hydralazine 0.2 mg/kg IM to a client who weighs 84 lb.
Available is hydralazine 20 mg/mL. How many mL should the nurse administer? (Round to the
nearest hundredth)
• A. 0.19 mL
• B. 0.38 mL
• C. 0.76 mL
• D. 1.68 mL
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ B. 0.38 mL
Rationale: First, convert weight to kg: 84 lb / 2.2 = 38.18 kg. Then, calculate the dose: 0.2 mg/kg
x 38.18 kg = 7.636 mg. Finally, calculate the volume: 7.636 mg / 20 mg x 1 mL = 0.3818 mL.
Round to the nearest hundredth to get 0.38 mL.
6. A nurse is preparing to administer cefazolin 500 mg IM to a client. Available is cefazolin
powder 500 mg vial. The nurse reconstitutes the powder adding 2 mL of sterile water to yield
a final concentration of cefazolin 225 mg/mL. How many mL should the nurse administer?
(Round to the nearest tenth)
• A. 1.1 mL
• B. 1.5 mL
• C. 2.2 mL
• D. 2.5 mL
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ C. 2.2 mL
Rationale: Use the formula: Desired Dose / Have x Quantity. The concentration is 225 mg/mL.
, 500 mg / 225 mg x 1 mL = 2.222... mL. Rounding to the nearest tenth gives 2.2 mL. Option A is
the volume for a 250 mg dose.
7. A nurse in a long term care facility is preparing to administer rivastigmine 3 mg P.O. twice
daily to a client who has Alzheimer's disease. Available is rivastigmine 1.5 mg/capsule. How

• C. 2 capsules
• D. 3 capsules
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ C. 2 capsules
Rationale: Use the formula: Desired Dose / Have x Quantity. 3 mg / 1.5 mg x 1 capsule = 2
capsules. The other options are incorrect.
8. A nurse is preparing to administer cefazolin 500 mg IM every 12 hr. Available is cefazolin
injection 330 mg/mL. How many mL should the nurse administer per dose? (Round to the
nearest tenth)
• A. 0.7 mL
• B. 1.5 mL
• C. 2.2 mL
• D. 3.3 mL
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ B. 1.5 mL
Rationale: Use the formula: Desired Dose / Have x Quantity. 500 mg / 330 mg x 1 mL = 1.515...
mL. Rounding to the nearest tenth gives 1.5 mL. The other options are incorrect.
9. The nurse is preparing to administer a 1,500 mL IV fluid bolus of 0.9% sodium chloride to a
client. How many liters should the nurse administer? (Round to the nearest tenth)
• A. 0.15 L
