HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: The correct answer is A: 440 mL. To determine the deficit in milliliters, we need to calculate the total intake and compare it to the total output. Total intake is calculated as follows: 2 (8oz cups of coffee) + 1 (16oz serving of clear soup) + 1 (pint of water) = 16oz + 16oz + 16oz = 48oz = 1,420 mL. The total output from the drainage bag is 1,000 mL. Therefore, the deficit is 1,420 mL (total intake) - 1,000 mL (total output) = 420 mL. However, since the patient consumed a clear diet, we should also subtract the insensible losses which are typically around 20% of the total intake. 20% of 1,420 mL = 284 mL. Subtracting this from the initial deficit of 420 mL gives us a final deficit of 420 mL

Correct Answer: A

Rationale: To convert centimeters to inches, we use the conversion factor 1 inch = 2.54 centimeters. Therefore, to convert 65.4 centimeters to inches, we divide 65.4 by 2.54. The calculation is 65.4 / 2.54 = 25.74 inches. This is why choice A (25.74) is correct. Choices B, C, and D are incorrect as they do not correctly convert centimeters to inches.

Correct Answer: A

Rationale: To find the number of days it will take the man to read 798 pages, first calculate the total number of chapters: 798 pages / (6 pages/chapter) = 133 chapters. Since he reads 2 chapters a day, divide the total chapters by 2 to get 133 chapters / 2 chapters/day = 66.5 days. Therefore, the correct answer is A: 66 & 1/2. Incorrect Choices: B: 399 - Incorrect as it does not reflect the correct calculation. C: 75 & 1/2 - Incorrect, the calculation is incorrect. D: 133 - Incorrect, this represents the total number of chapters, not the number of days.

Correct Answer: A

Rationale: To find x in the proportion 6:10=24:x, we first calculate the ratio of the given numbers, 6/10=24/x. Simplifying, we get 0.6=24/x. Cross multiplying, we get x=24/0.6=40. Therefore, the correct answer is A. Choice B is incorrect as it does not satisfy the proportion. Choice C is incorrect as it is too large compared to the correct answer. Choice D is incorrect as it is too small compared to the correct answer.

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%.
