HESI A2 Mathematics Practice Test 2026–2027
1. A nurse is preparing a patient for discharge and must document the patient's weight
in kilograms. The patient's chart notes a weight of 176 pounds. Using the conversion
factor 1 kg = 2.2 lb, what is the patient's weight in kilograms?
A. 80 kg
B. 82 kg
C. 84 kg
D. 86 kg
Correct Answer: A. 80 kg
*Rationale: To convert pounds to kilograms, divide the weight in pounds by 2.2. 176 ÷
2.2 = 80 kg. The other options result from common calculation errors or using an
incorrect conversion factor.*
2. A patient is prescribed 0.75 grams of a medication. The pharmacy dispenses tablets
containing 250 mg each. How many tablets should the nurse administer?
A. 2 tablets
B. 2.5 tablets
C. 3 tablets
D. 4 tablets
Correct Answer: C. 3 tablets
*Rationale: First convert grams to milligrams: 0.75 g × 1,000 = 750 mg. Then divide the
prescribed dose by the tablet strength: 750 mg ÷ 250 mg/tablet = 3 tablets.*
,3. A student scored 34 out of 40 on a practice examination. What percentage score did
the student earn?
A. 75%
B. 80%
C. 85%
D. 90%
Correct Answer: C. 85%
*Rationale: To find the percentage, divide the score earned by the total possible points
and multiply by 100. 34 ÷ 40 = 0.85. Then multiply by 100: 0.85 × 100 = 85%.*
4. A nurse needs to convert 1545 military time to standard 12-hour time. How should
this be documented?
A. 3:45 AM
B. 3:45 PM
C. 5:45 AM
D. 5:45 PM
Correct Answer: B. 3:45 PM
*Rationale: For military times greater than 1200, subtract 1200 to convert to standard
time. 1545 − 1200 = 345, which is written as 3:45 PM. Since the original time is greater
than 1200, it falls in the afternoon/evening period.*
,5. A medication order requires 2.5 liters of IV fluid to be infused over 12 hours. What is
the correct flow rate in milliliters per hour?
A. 180 mL/hr
B. 200 mL/hr
C. 208 mL/hr
D. 250 mL/hr
Correct Answer: C. 208 mL/hr
*Rationale: First convert liters to milliliters: 2.5 L × 1,000 = 2,500 mL. Then divide by the
number of hours: 2,500 mL ÷ 12 hours = 208.33 mL/hr, which rounds to 208 mL/hr.*
6. Simplify the following expression: 8 + 2 × (5 − 3)²
A. 16
B. 20
C. 24
D. 40
Correct Answer: A. 16
*Rationale: Following the order of operations (PEMDAS), first solve inside parentheses:
5 − 3 = 2. Next, apply the exponent: 2² = 4. Then multiply: 2 × 4 = 8. Finally, add: 8 + 8 =
16.*
7. A patient's fluid intake for the shift includes 240 mL of water, 180 mL of juice, and 120
mL of broth. What is the total intake in liters?
, A. 0.44 L
B. 0.54 L
C. 0.64 L
D. 5.4 L
Correct Answer: B. 0.54 L
*Rationale: First find the total intake in milliliters: 240 + 180 + 120 = 540 mL. Then
convert to liters by dividing by 1,000: 540 ÷ 1,000 = 0.54 L.*
8. Solve for x: 3x + 7 = 31
A. 6
B. 8
C. 10
D. 12
Correct Answer: B. 8
*Rationale: Subtract 7 from both sides: 3x = 24. Then divide both sides by 3: x = 8.*
9. What is the least common denominator (LCD) for the fractions 2/3 and 5/6?
A. 3
B. 6
C. 12
D. 18
