HESI A2 Math Practice Exam Questions
Question 1 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 2 of 5
Add: 1.332 + 0.067
Correct Answer: A
Rationale: To add 1.332 and 0.067, start from the rightmost digit and move left. Add 2 + 7 (9), then 3 + 6 (9), and 1 + 0 (1). The sum is 1.399, making choice A the correct answer. Choices B, C, and D are incorrect as they do not match the correct sum obtained through the addition process.
Question 3 of 5
A baseball team won 72 games. This was 90% of the games it played. How many games did it play?
Correct Answer: B
Rationale: To find the total number of games played, we divide the number of games won (72) by the percentage of games won (90%). This gives us 72 / 0.90 = 80 games played. Therefore, choice B is correct. Choice A (75) is incorrect because it does not account for the percentage of games won. Choice C (85) is incorrect as it overestimates the total number of games played. Choice D (100) is incorrect as it does not reflect the fact that the team won only 90% of the games played.
Question 4 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 5 of 5
How many centimeters are in a foot?
Correct Answer: C
Rationale: The correct answer is C: 30.48 cm. The conversion factor for feet to centimeters is 1 foot = 30.48 cm. To convert feet to centimeters, you multiply the number of feet by 30.48. Therefore, there are 30.48 cm in a foot. Choice A (30 cm) and Choice B (31.5 cm) are incorrect because they do not accurately represent the conversion factor from feet to centimeters. Choice D (35 cm) is also incorrect because it is not the standard conversion factor for feet to centimeters. Be sure to use the correct conversion factor of 30.48 cm when converting between feet and centimeters.
