HESI A2 Entrance Exam Practice Questions With
Correct Answers And Detailed Rationales 2026-
2027
Question 1 [Mathematics]
A nurse is preparing a medication and needs to administer 0.75 grams of a drug. The
available tablets are 250 mg each. How many tablets should the nurse administer?
A. 2 tablets
B. 3 tablets
1. C. 4 tablets
2. D. 5 tablets
Correct Answer: B
Rationale: First, convert grams to milligrams: 0.75 g = 750 mg. Then divide the desired
dose by the dose per tablet: 750 mg / 250 mg per tablet = 3 tablets. This is a common
conversion question on the HESI A2 math section.
Question 2 [Mathematics]
A patient is to receive 1,000 mL of normal saline over 8 hours. The IV tubing has a
drip factor of 15 gtt/mL. What is the drip rate in drops per minute?
3. A. 21 gtt/min
4. B. 31 gtt/min
5. C. 42 gtt/min
6. D. 63 gtt/min
Correct Answer: B
Rationale: Using the formula: (Total volume x Drip factor) / Time in minutes. (1,000 mL x
15 gtt/mL) / 480 minutes = 15, = 31.25 gtt/min, rounded to 31 gtt/min. First,
calculate the hourly rate: 1,000 mL / 8 hours = 125 mL/hour. Then convert to minutes: 125
mL/60 min = 2.083 mL/min. Multiply by drip factor: 2.083 x 15 = 31.25 gtt/min.
Question 3 [Mathematics]
What is 3/8 expressed as a decimal?
7. A. 0.25
,8. B. 0.375
9. C. 0.4
10. D. 0.625
Correct Answer: B
Rationale: To convert 3/8 to a decimal, divide 3 by 8: = 0.375. This is a fundamental
fraction-to-decimal conversion that appears frequently on the HESI A2 math section. 1/4 =
0.25 (A), 2/5 = 0.4 (C), and 5/8 = 0.625 (D).
Question 4 [Mathematics]
A recipe calls for a ratio of 2 parts flour to 3 parts sugar. If a baker uses 8 cups of
flour, how many cups of sugar are needed?
11. A. 6 cups
12. B. 10 cups
13. C. 12 cups
14. D. 16 cups
Correct Answer: C
Rationale: The ratio of flour to sugar is 2:3. If 8 cups of flour are used, set up a proportion:
2/3 = 8/x. Cross-multiply: 2x = 24, so x = 12 cups of sugar. Alternatively, 8 cups of flour is 4
times the original 2 cups, so multiply 3 cups of sugar by 4 to get 12 cups.
Question 5 [Mathematics]
If x + 5 = 12, what is the value of x?
15. A. 5
16. B. 6
17. C. 7
18. D. 8
Correct Answer: C
Rationale: To solve for x, subtract 5 from both sides of the equation: x + 5 - 5 = 12 - 5, so x =
7. This is a basic one-step algebraic equation common on the HESI A2.
Question 6 [Mathematics]
, A patient weighs 154 pounds. What is the patient's weight in kilograms? (Round to
the nearest whole number.)
19. A. 68 kg
20. B. 70 kg
21. C. 72 kg
22. D. 75 kg
Correct Answer: B
Rationale: To convert pounds to kilograms, divide by 2.2: .2 = 70 kg. This is one of
the most important conversions in healthcare and appears frequently on the HESI A2.
Remember: 1 kg = 2.2 lbs.
Question 7 [Mathematics]
What is 45% of 200?
23. A. 80
24. B. 85
25. C. 90
26. D. 95
Correct Answer: C
Rationale: To find 45% of 200, convert 45% to a decimal (0.45) and multiply by 200: 0.45 x
200 = 90. Alternatively, find 10% of 200 (20), multiply by 4 (80), then add half of 20 (10) to
get 90.
Question 8 [Mathematics]
A nurse needs to give a patient 500 mg of a medication. The available liquid
suspension is 250 mg/5 mL. How many mL should the nurse administer?
27. A. 5 mL
28. B. 10 mL
29. C. 15 mL
30. D. 20 mL
Correct Answer: B
Rationale: Set up a proportion: 250 mg / 5 mL = 500 mg / x mL. Cross-multiply: 250x =
2,500, so x = 10 mL. Alternatively, 500 mg is twice 250 mg, so you need twice the volume: 2
x 5 mL = 10 mL.
