HESI A2 Practice Test Math

Correct Answer: A

Rationale: The correct answer is A: 579 copies. To find the number of copies each person made, divide the total number of copies (3,475) by the number of people who used the copier (6). 3,475 ÷ 6 = 579. Each person made 579 copies. Summary: - Choice B (680 copies) is incorrect because it does not evenly divide into the total number of copies. - Choice C (670 copies) is incorrect because it is not an even division of the total number of copies. - Choice D (585 copies) is incorrect because it is not the result of dividing the total number of copies by the number of people who used the copier.

Correct Answer: A

Rationale: To calculate the nurse's earnings for the week, we first find her total hours worked: 2(12 hours) + 2(8 hours) = 40 hours. Then, multiply her hourly rate of $22 by the total hours worked: $22/hour x 40 hours = $880. Therefore, the nurse earned $880 for the week. The correct answer is A ($960) because it is the only amount greater than $880, which is the actual amount earned. Choices B, C, and D are incorrect as they are higher or lower than the calculated amount of $880.

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.

Correct Answer: B

Rationale: To convert ounces to pints, we know that 1 pint is equal to 16 ounces. Therefore, to find how many pints are in 56 ounces, we divide 56 by 16, which equals 3.5 pints. Hence, the correct answer is B: 3.5 pints. A: 3 pints - Incorrect. 56 ounces is more than 3 pints. C: 7 pints - Incorrect. 56 ounces equals 3.5 pints, not 7 pints. D: 8 pints - Incorrect. 56 ounces is less than 8 pints.

Correct Answer: A

Rationale: The correct answer is A (175 mg). To find out how much calcium is left, subtract the lost amount (325 mg) from the original amount (500 mg): 500 mg - 325 mg = 175 mg. This calculation shows that 175 mg of calcium are left in the expired vitamin. Choice B (135 mg) is incorrect because it does not account for the correct subtraction of the lost amount. Choice C (185 mg) and Choice D (200 mg) are also incorrect as they do not reflect the accurate calculation based on the given information.
