Section 1: Mathematics (Questions 1–35)
1. A nurse is preparing to administer 0.9% sodium chloride 1,000 mL over 8 hours. The drop
factor is 15 gtt/mL. What is the correct drip rate in drops per minute?
A. 21 gtt/min
B. 31 gtt/min
C. 42 gtt/min
D. 15 gtt/min
Correct Answer: B. 31 gtt/min
Rationale: Formula: (Volume × Drop factor) ÷ Time in minutes. (1,000 mL × 15 gtt/mL) ÷ (8 ×
60 min) = 15,000 ÷ 480 = 31.25, rounded to 31 gtt/min. Option A is incorrect (calculation error).
Option C would be for a 10-hour infusion. Option D ignores the drop factor.
2. Convert 2.5 kilograms to pounds. (1 kg = 2.2 lb)
A. 5.5 lb
B. 4.5 lb
C. 5.0 lb
D. 6.0 lb
Correct Answer: A. 5.5 lb
Rationale: 2.5 kg × 2.2 lb/kg = 5.5 lb. Option B results from subtracting instead of
multiplying. Option C results from using 2.0 as the conversion factor. Option D is incorrect.
3. A medication order reads: Administer 250 mg of a drug. The available vial contains 500
mg/5 mL. How many mL will the nurse administer?
A. 1.5 mL
B. 2.5 mL
,C. 3.0 mL
D. 5.0 mL
Correct Answer: B. 2.5 mL
Rationale: Desired/Have × Quantity = 250 mg/500 mg × 5 mL = 2.5 mL. Option A is
incorrect. Option C would require 600 mg. Option D would deliver 500 mg.
4. Which of the following is the equivalent of 0.75 as a fraction in simplest form?
A. 1/2
B. 2/3
C. 3/4
D. 4/5
Correct Answer: C. 3/4
Rationale: 0.75 = 75/100 = 3/4 when reduced by dividing numerator and denominator by
25. Option A = 0.5. Option B ≈ 0.667. Option D = 0.8.
5. A patient weighs 165 lb. What is the patient's weight in kilograms? (Round to the nearest
tenth.)
A. 72.7 kg
B. 75.0 kg
C. 80.5 kg
D. 68.2 kg
Correct Answer: B. 75.0 kg
Rationale: 165 lb ÷ 2.2 = 75.0 kg. Option A results from dividing by 2.27. Option C results
from multiplying by 0.488. Option D is incorrect.
6. Solve for x: 3x + 12 = 45
A. 9
B. 11
C. 15
D. 19
, Correct Answer: B. 11
Rationale: 3x + 12 = 45 → 3x = 33 → x = 11. Option A results from dividing 45 by 5. Option C
results from subtracting 12 from 45 and dividing by 2.2. Option D is incorrect.
7. A nurse needs to infuse 500 mL of IV fluid over 4 hours using an infusion pump. What is the
flow rate in mL/hr?
A. 100 mL/hr
B. 125 mL/hr
C. 150 mL/hr
D. 200 mL/hr
Correct Answer: B. 125 mL/hr
Rationale: 500 mL ÷ 4 hr = 125 mL/hr. Option A would infuse over 5 hours. Option C would
infuse 600 mL in 4 hours. Option D would infuse 800 mL in 4 hours.
8. What is 15% of 240?
A. 24
B. 30
C. 36
D. 40
Correct Answer: C. 36
Rationale: 0.15 × 240 = 36. Option A = 10% of 240. Option B = 12.5% of 240. Option D is
incorrect.
9. A patient's temperature is 38.9°C. Convert this to Fahrenheit. (F = C × 9/5 + 32)
A. 100.0°F
B. 101.2°F
C. 102.0°F
D. 103.4°F
Correct Answer: C. 102.0°F
, Rationale: (38.9 × 9/5) + 32 = (38.9 × 1.8) + 32 = 70.02 + 32 = 102.02°F ≈ 102.0°F. Option A is
incorrect. Option B is incorrect. Option D would require 39.7°C.
10. A nurse practitioner orders 1.5 mg of a medication. The pharmacy supplies 0.5 mg tablets.
How many tablets will the nurse administer?
A. 1 tablet
B. 2 tablets
C. 3 tablets
D. 4 tablets
Correct Answer: C. 3 tablets
Rationale: 1.5 mg ÷ 0.5 mg/tablet = 3 tablets. Option A delivers 0.5 mg. Option B delivers
1.0 mg. Option D delivers 2.0 mg.
11. Which of the following is the correct metric conversion for 1,500 mcg to mg?
A. 0.15 mg
B. 1.5 mg
C. 15 mg
D. 150 mg
Correct Answer: B. 1.5 mg
Rationale: 1,500 mcg ÷ 1,000 = 1.5 mg. Option A is incorrect. Option C = 15,000 mcg. Option
D = 150,000 mcg.
12. A nurse is calculating intake and output. The patient drank 8 oz of coffee, 4 oz of juice, and
12 oz of water. What is the total intake in mL? (1 oz = 30 mL)
A. 600 mL
B. 720 mL
C. 840 mL
D. 960 mL
Correct Answer: B. 720 mL
