Introduction
The HESI Admission Assessment (A2) Entrance Examination measures the academic readiness and
critical thinking ability required for success in a professional nursing program. This verified
question bank reflects the official HESI A2 domain blueprint and systematically covers its core
areas: Mathematics and Dosage Calculations; Reading Comprehension and Critical Thinking;
Vocabulary and General Knowledge; Grammar and English Language Mechanics; Biology and
Cellular Processes; Anatomy and Physiology; Chemistry and Basic Physics; and Test-Taking
Strategies and Nursing School Admissions Criteria. Every item pairs a verified correct answer with
a concise rationale that reinforces the underlying principle and clarifies why the remaining options
fail, converting each question into a targeted study point. Mastery of this content supports academic
progression and strengthens the readiness demanded in nursing school admission execution, from
accurate dosage computation and scientific reasoning to language mechanics, evidence-based
comprehension, and the disciplined test-taking judgment that competitive programs expect.
1. Express the fraction 3/4 as a decimal.
A. 0.34
B. 0.43
C. 0.75
D. 1.34
Correct Answer: C. 0.75
Rationale: Dividing the numerator 3 by the denominator 4 gives 0.75. The other decimals confuse
numerator and denominator or add the digits instead of dividing.
2. What is 15 percent of 240?
A. 16
B. 36
C. 36.0
D. 160
Correct Answer: B. 36
Rationale: Multiplying 240 by 0.15 yields 36. Sixteen reverses the digits, and 160 confuses
percentage with subtraction.
3. A bag contains red and blue marbles in a ratio of 3 to 5. If there are 48 marbles altogether, how
many are blue?
A. 30
, B. 18
C. 24
D. 40
Correct Answer: A. 30
Rationale: The ratio has 8 total parts, so each part equals 48 divided by 8, or 6. Blue marbles make
up 5 parts: 5 times 6 equals 30. Eighteen counts the red marbles, and the others skip the
proportional step.
4. What number does the Roman numeral XIV represent?
A. 14
B. 16
C. 9
D. 41
Correct Answer: A. 14
Rationale: X equals 10, IV equals 4, so XIV is 14. Sixteen reads XVI, nine reads IX, and 41 reads XLI.
5. A prescription calls for 2.5 kg of a substance. How many grams is this?
A. 250 g
B. 25,000 g
C. 0.0025 g
D. 2,500 g
Correct Answer: D. 2,500 g
Rationale: One kilogram contains 1,000 grams, so 2.5 times 1,000 equals 2,500 g. The other choices
shift the decimal point in the wrong direction.
6. A nurse must administer 250 mg of a medication. The solution on hand contains 500 mg in 2 mL.
How many milliliters should be given?
A. 1 mL
B. 2 mL
C. 0.5 mL
D. 4 mL
Correct Answer: A. 1 mL
Rationale: Setting up the proportion 500 mg over 2 mL equals 250 mg over X gives X = 1 mL. Two
milliliters would deliver the full 500 mg, and the other volumes ignore the concentration.
7. A provider orders 0.5 g of a drug. Tablets are available in 250 mg each. How many tablets should
be given?
A. 1 tablet
B. 2 tablets
C. 3 tablets
D. 0.5 tablet
Correct Answer: B. 2 tablets
, Rationale: Converting 0.5 g to 500 mg, the dose divided by 250 mg per tablet yields 2 tablets. One
tablet delivers only half the order, and the remaining counts miscalculate the conversion.
8. What is 2:45 PM expressed in military (24-hour) time?
A. 0245
B. 1245
C. 2445
D. 1445
Correct Answer: D. 1445
Rationale: Afternoon times add 12 hours to the clock hour: 2 plus 12 equals 14, giving 1445. The
value 0245 is the morning equivalent, and the others use invalid hour formats.
9. What is the sum of 4.25 and 3.7?
A. 7.32
B. 7.95
C. 4.62
D. 79.5
Correct Answer: B. 7.95
Rationale: Aligning the decimal points and adding gives 4.25 plus 3.70, which equals 7.95. The other
totals misplace columns or the decimal point.
10. If 2 fluid ounces equal 60 mL, how many mL are in 5 fluid ounces?
A. 120 mL
B. 62 mL
C. 150 mL
D. 300 mL
Correct Answer: C. 150 mL
Rationale: Each ounce is 30 mL, so 5 ounces times 30 equals 150 mL. One hundred twenty covers
only 4 ounces, and 300 assumes 60 mL per ounce.
11. A temperature rises from 80 degrees to 92 degrees. What is the percent increase?
A. 12 percent
B. 80 percent
C. 150 percent
D. 15 percent
Correct Answer: D. 15 percent
Rationale: The increase of 12 degrees divided by the starting value of 80 equals 0.15, or 15 percent.
Twelve is the raw change, not the percentage.
12. What is the product of 2 1/2 and 3?
A. 6.5
B. 5
C. 23.5
