HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To find how much the student earned for working 6 hours, we can use the formula: Earnings = (Total pay / Total hours) x Hours worked. In this case, Earnings = ($120 / 10 hours) x 6 hours = $72. Therefore, the correct answer is A: $72. Choice B, $90, is incorrect as it does not match the calculated amount. Choice C, $80, is also incorrect. Choice D, $50, is incorrect because it is too low based on the calculated earnings for 6 hours.

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: D

Rationale: To find 25% of 400, you multiply 400 by 0.25 (25% as a decimal). So, 400 * 0.25 = 100. Therefore, the correct answer is D. Choice A (800) is incorrect as it is 200% of 400. Choice B (10,000) is incorrect as it is 2500% of 400. Choice C (200) is incorrect as it is 50% of 400.

Correct Answer: B

Rationale: To convert milligrams to grams, divide by 1000 since 1 gram = 1000 milligrams. 150 milligrams ÷ 1000 = 0.15 grams. Therefore, the correct answer is B. Explanation for other choices: A: 0.015 grams = Incorrect, a decimal point is missing. C: 1.5 grams = Incorrect, this would be the result if the milligrams were converted to grams as if they were micrograms. D: 15 grams = Incorrect, this would be the result if the milligrams were mistakenly multiplied by 100 instead of divided by 1000.

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.
