HESI A2 Practice Test Math

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.

Correct Answer: C

Rationale: To calculate 0.9 divided by 3, we divide 0.9 by 3, which equals 0.3. This is the correct answer (C) because dividing 0.9 by 3 results in 0.3. Option A (0) is incorrect as the division does not equal 0. Option B (3) is incorrect as the result is not equal to 3. Option D (9) is incorrect as the division does not equal 9. Therefore, the correct answer is C (0.3).

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.

Correct Answer: A

Rationale: To convert fluid ounces to gallons, we know that 1 gallon equals 128 fluid ounces. Therefore, to find how many gallons are in 576 fluid ounces, we divide 576 by 128, which equals 4. So, the correct answer is A: 4 gallons. Option B (5 gallons) is incorrect because the conversion calculation shows that 576 fluid ounces is equivalent to 4 gallons, not 5 gallons. Option C (6 gallons) is incorrect as well, as 576 fluid ounces is less than 6 gallons. Option D (3 gallons) is incorrect because the conversion calculation clearly demonstrates that 576 fluid ounces is equal to 4 gallons, not 3 gallons.
