HESI A2 Practice Test Math Questions
Question 1 of 5
A delivery of medical supplies includes 36 boxes. If each box weighs 2.5 pounds, what is the total weight of the delivery?
Correct Answer: A
Rationale: To find the total weight, multiply the number of boxes by the weight of each box. 36 boxes * 2.5 pounds = 90 pounds. Option A is correct because it correctly calculates the total weight. Option B (75 pounds) is incorrect as it doesn't account for all 36 boxes. Option C (120 pounds) is incorrect as it overestimates the weight. Option D (100 pounds) is incorrect as it underestimates the weight by not considering all boxes.
Question 2 of 5
A woman received a bottle of perfume as a present. The bottle contains 1/2 oz of perfume. How many milliliters is this?
Correct Answer: A
Rationale: To convert ounces to milliliters, we use the conversion factor: 1 oz = 29.5735 mL. Since the bottle contains 1/2 oz, we multiply 1/2 by 29.5735 to get 14.78675 mL. Rounding up, the closest option is 15 mL (choice A). Choices B, C, and D are incorrect as they do not match the calculated conversion from ounces to milliliters.
Question 3 of 5
What is the result of subtracting 7 7/10 from 3 4/5?
Correct Answer: A
Rationale: To subtract mixed numbers, convert them to improper fractions. 3 4/5 = 19/5 and 7 7/10 = 77/10. Subtracting gives 19/5 - 77/10 = 38/10 - 77/10 = -39/10. Convert back to a mixed number: -39/10 = -3 9/10 (choice A). Other choices are incorrect as they do not match the correct result.
Question 4 of 5
How many ounces are in 8 & 1/4 pints?
Correct Answer: C
Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, to find the number of ounces in 8 & 1/4 pints, we multiply 8 by 16 (128 oz) and add 1/4 of 16 (4 oz). This gives us a total of 132 ounces (128 + 4). Therefore, the correct answer is C (132 oz). Option A is incorrect as it is the result of miscalculating the conversion. Option B and D are incorrect as they do not account for the additional 1/4 pint.
Question 5 of 5
A patient needs to increase his calcium intake. If each tablet contains 500 mg of calcium and the patient needs to take 1,500 mg per day, how many tablets should the patient take?
Correct Answer: A
Rationale: The correct answer is A: 3 tablets. To reach the daily intake of 1,500 mg of calcium, the patient should take 1,500 mg ÷ 500 mg per tablet = 3 tablets. Taking 3 tablets will provide the required 1,500 mg of calcium. Choice B (4 tablets) would exceed the required amount, choice C (2 tablets) would be insufficient, and choice D (5 tablets) would exceed the required amount as well. Therefore, A (3 tablets) is the correct answer.
