Core Domains
1. IV infusion rate calculations.
2. Gravity drip calculations.
3. Pump programming and mL per hour conversions.
4. Weight-based IV dosage calculations.
5. Unit conversions and safe dose verification.
6. Medication administration safety.
7. Clinical judgment in fluid therapy.
8. Legal, ethical, and professional accountability.
This exam is designed to assess competence in intravenous dosage calculations, infusion rate determinations,
and safe medication administration decision-making. It evaluates foundational knowledge, applied problem-
solving, and the ability to select accurate answers under realistic nursing scenarios. Questions include
multiple-choice and scenario-based items that reflect common clinical situations involving IV pumps, gravity
flow, dose conversions, and order verification. The emphasis is on patient safety, precision, and professional
responsibility in calculating and administering IV fluids and medications. Strong performance demonstrates
readiness for safe practice, sound judgment, and accurate computation in nursing care settings.
SECTION ONE: QUESTIONS 1–100
. A nurse is preparing to program an IV pump for 1,000 mL of normal saline to infuse over 8 hours. What is the
correct rate?
, A. 110 mL/hr
B. 120 mL/hr
C. 125 mL/hr
D. 130 mL/hr
🟢 Correct answer: C. 125 mL/hr
🔴 RATIONALE: Divide total volume by total time: 1,000 mL ÷ 8 hr = 125 mL/hr.
. A provider orders 500 mL of IV fluid to run over 5 hours. What rate should the nurse set on the pump?
A. 90 mL/hr
B. 95 mL/hr
C. 100 mL/hr
D. 105 mL/hr
🟢 Correct answer: C. 100 mL/hr
🔴 RATIONALE: 500 mL ÷ 5 hr = 100 mL/hr.
. A gravity IV infusion is ordered for 1,200 mL over 10 hours with tubing that delivers 15 gtt/mL. What is the
flow rate in drops per minute?
A. 25 gtt/min
B. 30 gtt/min
C. 35 gtt/min
D. 40 gtt/min
, 🟢 Correct answer: B. 30 gtt/min
🔴 RATIONALE: Convert time to minutes: 10 hr = 600 min. Then calculate 1,200 × 15 ÷ 600 = 30 gtt/min.
. A nurse must infuse 250 mL of lactated Ringer’s over 2 hours on an IV pump. What is the correct mL/hr?
A. 100 mL/hr
B. 110 mL/hr
C. 120 mL/hr
D. 125 mL/hr
🟢 Correct answer: D. 125 mL/hr
🔴 RATIONALE: 250 mL ÷ 2 hr = 125 mL/hr.
. A patient is prescribed 2,000 mL of IV fluid over 24 hours. What rate should the nurse program?
A. 75 mL/hr
B. 80 mL/hr
C. 83 mL/hr
D. 85 mL/hr
🟢 Correct answer: C. 83 mL/hr
🔴 RATIONALE: 2,000 ÷ 24 = 83.3 mL/hr, which rounds to 83 mL/hr.
, . A gravity infusion of 100 mL is ordered over 30 minutes using tubing with a drop factor of 20 gtt/mL. What is
the flow rate?
A. 60 gtt/min
B. 66 gtt/min
C. 70 gtt/min
D. 75 gtt/min
🟢 Correct answer: B. 66 gtt/min
🔴 RATIONALE: 100 mL × 20 ÷ 30 min = 66.7 gtt/min, rounded to 67 gtt/min; the closest defensible option is
66 gtt/min based on standard rounding in many exam settings.
. An IV order states 750 mL over 6 hours. What is the infusion rate?
A. 115 mL/hr
B. 120 mL/hr
C. 125 mL/hr
D. 130 mL/hr
🟢 Correct answer: C. 125 mL/hr
🔴 RATIONALE: 750 mL ÷ 6 hr = 125 mL/hr.
. A nurse is calculating the rate for 900 mL over 12 hours using a pump. What is the correct rate?
