HESI A2 Math Practice Exam Questions

Question 1 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 2 of 5

A table shows the average blood pressure readings for different age groups. How do you determine the highest average systolic pressure?

Correct Answer: A

Rationale: The correct answer is A because to determine the highest average systolic pressure, you need to find the largest number in the "systolic pressure" column. This is because the average is calculated based on all the values in the column, and the highest number will have the most significant impact on the average. By finding the largest number, you ensure that the highest average systolic pressure is accurately identified. Option B is incorrect because comparing the means of each age group does not specifically pinpoint the highest average systolic pressure. Option C is incorrect as it calculates the overall average rather than focusing on the highest value. Option D is incorrect as subtracting the lowest from the highest does not give the highest average systolic pressure.

Question 3 of 5

How many millimeters are in 5 meters?

Correct Answer: A

Rationale: To convert meters to millimeters, we know that 1 meter is equal to 1000 millimeters. Therefore, to find how many millimeters are in 5 meters, we multiply 5 by 1000 which equals 5000 millimeters. Choice A (5000 mm) is correct. Choices B, C, and D are incorrect as they do not accurately convert 5 meters to millimeters. Choice B (4000 mm) is incorrect because it underestimates the conversion. Choice C (5500 mm) is incorrect as it overestimates the conversion. Choice D (6000 mm) is also incorrect as it overestimates the conversion.

Question 4 of 5

A clinic sees an average of 25 patients every 4 hours. If the clinic is open for 8 hours, how many patients will they see in total?

Correct Answer: D

Rationale: To find the total number of patients seen in 8 hours, first calculate the number of patients seen in 1 hour (25/4 = 6.25). Then, multiply by 8 to get the total (6.25 * 8 = 50). Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not follow the correct calculation process. A, B, and C do not consider the rate of patients seen per hour or the total hours the clinic is open.

Question 5 of 5

How much paint do you need to paint the interior walls and floor of a rectangular swimming pool with dimensions 8m by 5m and a depth of 2m? (Assume one can of paint covers 10 sq m)

Correct Answer: C

Rationale: To calculate the total area to paint, we need to find the surface area of the walls and the floor separately. The surface area of the walls is 2*(8+5)*2 = 36 sq m. The floor area is 8*5 = 40 sq m. Adding these together gives 36 + 40 = 76 sq m. Since one can of paint covers 10 sq m, we need 76/10 = 7.6 cans of paint. Rounding up to the nearest whole number, we need 8 cans of paint, which is equivalent to 88 sq m. Therefore, the correct answer is C (88 sq m). Choice A (56 sq m) is incorrect as it does not consider the surface area of the floor. Choice B (72 sq m) is incorrect as it miscalculates the total area to paint. Choice D (104 sq m) is incorrect as it overestimates the amount of paint needed.
