Relias RN Advanced Math Ability Comprehensive Examination 2026/2027 | Verified Questions
,INTRODUCTION
This document contains 100 original verified questions designed for the Relias RN Advanced Math Ability
Comprehensive Certification Examination. The questions are organized across four core domains: Dosage
Calculations and IV Drip Rates (25 questions); Unit Conversions and Metric System (25 questions);
Pediatric and Weight-Based Calculations (25 questions); and Medication Administration and Safety
Principles (25 questions). Content is original and constructed to reinforce the official Relias RN Advanced
Math Ability course objectives for actual exam readiness and professional proficiency, aligned to the
2026/2027 academic year. Each question includes a correct answer and a rationale grounded in
foundational nursing mathematics curriculum and patient-safety calculation standards.
ACTUAL QUESTIONS
Domain 1: Dosage Calculations and IV Drip Rates
Question 1. Ordered: amoxicillin 500 mg PO. Available: 250 mg/5 mL suspension. How
many mL will the nurse administer?
A. 5 mL
B. 10 mL
C. 2.5 mL
D. 20 mL
Correct Answer: B
Rationale: Desired/Have × Volume = 500 mg / 250 mg × 5 mL = 10 mL. Dimensional analysis confirms
the volume to administer.
Question 2. An IV of 1000 mL is ordered to infuse over 8 hours. The drop factor is 15
gtt/mL. Calculate the flow rate in gtt/min.
A. 21 gtt/min
B. 42 gtt/min
C. 15 gtt/min
D. 31 gtt/min
Correct Answer: D
Rationale: Volume/Time (min) × Drop factor = 1000 mL / 480 min × 15 = 31.25 ≈ 31 gtt/min (rounded
to nearest whole number).
Question 3. Ordered: heparin 1000 units/hr IV. Available: heparin 25,000 units in 500 mL
D5W. What is the infusion rate in mL/hr?
A. 10 mL/hr
B. 20 mL/hr
C. 40 mL/hr
D. 50 mL/hr
Correct Answer: B

, Rationale: Concentration = 25,000 units / 500 mL = 50 units/mL. Rate = 1000 units/hr ÷ 50 units/mL
= 20 mL/hr.
Question 4. A client is to receive 1 L of normal saline over 10 hours. The IV pump is set in
mL/hr. What rate should be programmed?
A. 100 mL/hr
B. 50 mL/hr
C. 125 mL/hr
D. 200 mL/hr
Correct Answer: A
Rationale: 1000 mL ÷ 10 hr = 100 mL/hr. Electronic pumps are programmed in mL/hr.
Question 5. Ordered: morphine 4 mg IV push. Available: morphine 10 mg/mL. How many
mL will be administered?
A. 0.8 mL
B. 1.4 mL
C. 0.4 mL
D. 4 mL
Correct Answer: C
Rationale: 4 mg ÷ 10 mg/mL = 0.4 mL. Accurate measurement of small volumes is essential for IV push
safety.
Question 6. An IV is ordered at 75 mL/hr. The drop factor is 20 gtt/mL. Calculate gtt/min.
A. 25 gtt/min
B. 15 gtt/min
C. 37 gtt/min
D. 50 gtt/min
Correct Answer: A
Rationale: 75 mL/hr × 20 gtt/mL ÷ 60 min/hr = 25 gtt/min.
Question 7. Ordered: digoxin 0.125 mg PO daily. Available: digoxin 0.25 mg tablets. How
many tablets will be given?
A. 1 tablet
B. 2 tablets
C. 0.5 tablet
D. 0.25 tablet
Correct Answer: C
