HESI A2 Math Practice Test 2024

Correct Answer: B

Rationale: The military time 15:17:52 is equivalent to 3:17:52 PM in regular time. To convert from military time to regular time, we subtract 12 from the hour if it is greater than 12 to get the PM time. Therefore, 15 - 12 = 3, indicating it's in the afternoon. The correct answer is B (3:17 PM). Choice A (2:17 PM) is incorrect because 15 is greater than 12, so it would be in the afternoon. Choice C (5:17 AM) is incorrect because 15 is in the afternoon, not morning. Choice D (9:17 AM) is incorrect because 15 is in the afternoon, not morning.

Correct Answer: C

Rationale: The correct answer is C because the range of 5 degrees Celsius indicates the difference between the highest and lowest temperatures in the set is 5 degrees. This is the definition of range in statistics. A is incorrect because the range does not provide information about the average temperature. B is incorrect because the range only tells us the spread between the highest and lowest temperatures, not that all temperatures are within 5 degrees of each other. D is incorrect because the range does not indicate how many temperatures are in the set, just the difference between the highest and lowest temperatures.

Correct Answer: A

Rationale: To calculate the number of cakes needed, divide the total number of servings needed (70 students + 3 staff) by the number of servings per cake. Total servings needed = 70 + 3 = 73. 73 servings ÷ 24 servings per cake = 3 with a remainder of 1. Since we can't have a fraction of a cake, we need to round up to the nearest whole number. So, we need 4 cakes to ensure there are enough servings for everyone. Therefore, the correct answer is A: 4. Choice B (2) is incorrect because it doesn't provide enough servings for all students and staff members. Choice C (5) is incorrect as it would be an excessive amount of cakes. Choice D (3) is incorrect as it doesn't account for the remaining servings after dividing by 24.

Correct Answer: A

Rationale: To calculate the percentage of patients satisfied, divide the number of satisfied patients (120) by the total number of patients surveyed (150) and multiply by 100. So, (120/150) x 100 = 80%. Therefore, the correct answer is A (80%). Choice B (75%) is too low, Choice C (85%) is too high, and Choice D (90%) is also too high based on the given data. Thus, the correct percentage of patients satisfied is 80%.

Correct Answer: A

Rationale: To calculate the total number of patients monitored, we add the number of patients each nurse monitored: 6 + 8 + 12 = 26 patients. Therefore, the correct answer is A (26 patients). Nurse 1 monitored 6 patients, Nurse 2 monitored 8 patients, and Nurse 3 monitored 12 patients, totaling 26 patients. Choices B, C, and D are incorrect because they do not accurately represent the sum of patients monitored by all three nurses.
