HESI A2 Math Practice Exam Questions

Question 1 of 5

The physician ordered 16 mg of Ibuprofen per kg of body weight; on hand are 80 mg tablets. The child weighs 15 kg. How many tablets will you give?

Correct Answer: B

Rationale: To calculate the number of tablets needed: 1. Determine the total dosage needed: 16 mg/kg x 15 kg = 240 mg. 2. Divide the total dosage by the dosage per tablet: 240 mg ÷ 80 mg = 3 tablets. 3. The correct answer is B (2 tablets) as it is the nearest whole number to the calculated 3 tablets. Choice A is incorrect because it is less than the calculated amount. Choice C is incorrect as it is less than the required dosage. Choice D is incorrect as it is a non-integer value.

Question 2 of 5

After taking several practice tests, Brian improved the results of his GRE test by 30%. Given that the first time he took the test Brian answered 150 questions correctly, how many questions did he answer correctly on the second test?

Correct Answer: D

Rationale: To find out how many questions Brian answered correctly on the second test, we first calculate the 30% increase from his initial score of 150 questions. 30% of 150 is 45, so his new score is 150 + 45 = 195 questions. Therefore, the correct answer is D (195). Choice A (105) is incorrect because it is less than the initial score of 150. Choice B (120) is incorrect because it does not account for the 30% increase. Choice C (180) is incorrect as it is the result of adding 30% to the initial score, not the final score after the increase.

Question 3 of 5

Subtract 2 & 5/8 - 7/8 and reduce.

Correct Answer: C

Rationale: Failed to generate a rationale after 5 retries.

Question 4 of 5

How many yards are in a mile?

Correct Answer: A

Rationale: The correct answer is A: 1,760 yards in a mile. This is because 1 mile is equal to 1,760 yards. To convert miles to yards, you multiply the number of miles by 1,760. The other choices (B, C, D) are incorrect as they do not represent the accurate conversion factor for miles to yards. Option B (1,700) is too low, option C (1,800) is too high, and option D (1,750) is also incorrect. Therefore, the correct answer is A, 1,760 yards in a mile.

Question 5 of 5

What number is 44 equal to 25% of?

Correct Answer: A

Rationale: To find the number that 44 is 25% of, we divide 44 by 0.25 (which is 25% expressed as a decimal). 44 / 0.25 = 176. Therefore, 44 is equal to 25% of 176. Option A (176) is the correct answer. Option B (150), C (180), and D (120) are incorrect as they do not result in 44 when multiplied by 0.25.
