HESI A2 Practice Test Math

Correct Answer: A

Rationale: To convert a decimal to a percent, you multiply by 100. In this case, 0.98 * 100 = 98%. Therefore, the correct answer is A. Choice B is incorrect as it represents 9%, not 0.98%. Choice C is incorrect as it is the decimal form itself, not the percentage. Choice D is incorrect as it represents 99%, not 0.98%.

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: B

Rationale: To determine the sign of the product when multiplying positive and negative integers, we follow the rule: Positive * Negative = Negative. This is because when we multiply a positive number by a negative number, the result will always be negative. Hence, choice B is correct. Choice A is incorrect because the product is not always positive. Choice C is incorrect as the sign of the product is consistent regardless of specific numbers used. Choice D is incorrect as positive and negative integers can indeed be multiplied.

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: 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.
