SECTION A: ORIGINAL QUESTIONS WITH MULTIPLE CHOICE OPTIONS
Question 1
A nurse is preparing to administer dextrose 5% water (D5W) 250 mL IV to infuse over 2 hr. The
nurse should set 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. 175 mL/hr
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ B. 125 mL/hr
Rationale: To calculate the IV pump rate in mL/hr, divide the total volume by the total time in
hours: 250 mL ÷ 2 hr = 125 mL/hr. Option A (100 mL/hr) would infuse over 2.5 hours, which is
incorrect. Option C (150 mL/hr) would infuse the volume in approximately 1.67 hours. Option D
,(175 mL/hr) would infuse too rapidly in about 1.43 hours. The correct calculation ensures the
fluid is administered over the prescribed 2-hour period.
Question 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. 0.9 mL
B. 1.0 mL
C. 1.1 mL
D. 1.2 mL
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ C. 1.1 mL
Rationale: Using the formula: Volume to administer = Desired dose ÷ Available concentration.
250 mg ÷ 225 mg/mL = 1.11 mL, which rounds to 1.1 mL. Option A (0.9 mL) would only provide
202.5 mg of cefazolin. Option B (1.0 mL) would provide 225 mg, which is less than the
prescribed 250 mg. Option D (1.2 mL) would provide 270 mg, exceeding the prescribed dose.
The nurse should administer 1.1 mL to deliver the accurate 250 mg dose.
Question 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: To determine the number of tablets, divide the desired dose by the available dose
per tablet: 600 mg ÷ 200 mg/tablet = 3 tablets. Option A (1 tablet) would only provide 200 mg.
Option B (2 tablets) would provide 400 mg, which is insufficient. Option D (4 tablets) would
provide 800 mg, exceeding the prescribed dose. The nurse should administer 3 tablets to
achieve the correct 600 mg dose.
Question 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)
A. 1 mL
B. 2 mL
C. 3 mL
D. 4 mL
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ B. 2 mL
Rationale: Using the formula: Volume = Desired dose ÷ Available concentration. 20 mg ÷ 10
mg/mL = 2 mL. Option A (1 mL) would only provide 10 mg. Option C (3 mL) would provide 30
mg, exceeding the prescribed dose. Option D (4 mL) would provide 40 mg, which is double the
prescribed dose. The nurse should administer 2 mL to deliver the correct 20 mg dose of
furosemide.
Question 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. 0.28 mL
B. 0.33 mL
, C. 0.38 mL
D. 0.42 mL
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ C. 0.38 mL
Rationale: First, convert weight from pounds to kilograms: 84 lb ÷ 2.2 = 38.18 kg. Then calculate
the dose: 0.2 mg/kg × 38.18 kg = 7.64 mg. Finally, calculate volume: 7.64 mg ÷ 20 mg/mL = 0.38
mL. Option A (0.28 mL) would provide only 5.6 mg. Option B (0.33 mL) would provide 6.6 mg.
Option D (0.42 mL) would provide 8.4 mg, exceeding the prescribed dose. The nurse should
administer 0.38 mL.
Question 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. 1.8 mL
B. 2.0 mL
C. 2.2 mL
D. 2.5 mL
✔✔✔ CORRECT 100% ANSWER 📌✔❤❤ C. 2.2 mL
Rationale: Using the formula: Volume = Desired dose ÷ Available concentration. 500 mg ÷ 225
mg/mL = 2.22 mL, which rounds to 2.2 mL. Option A (1.8 mL) would provide only 405 mg.
Option B (2.0 mL) would provide 450 mg, which is less than prescribed. Option D (2.5 mL) would
provide 562.5 mg, exceeding the prescribed dose. The nurse should administer 2.2 mL to deliver
the accurate 500 mg dose.
