HESI A2 Practice Test Math Questions
Question 1 of 5
A nurse working at the hospital earns $22 per hour. She worked two 12-hour shifts and two 8-hour shifts during the week. How much did she earn for the week?
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.
Question 2 of 5
How many gallons are in 576 fluid ounces?
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.
Question 3 of 5
How many centimeters are in 1 foot?
Correct Answer: A
Rationale: The correct answer is A: 30.48. To convert feet to centimeters, we use the conversion factor: 1 foot = 30.48 centimeters. This is because 1 foot is equivalent to 12 inches, and 1 inch is equal to 2.54 centimeters. So, 1 foot = 12 inches * 2.54 cm/inch = 30.48 cm. Choices B, C, and D are incorrect because they do not correctly represent the conversion factor from feet to centimeters. B, 35 cm, is too high; C, 25 cm, is too low; and D, 40 cm, is also too high.
Question 4 of 5
Solve for x: 3(x - 4) = 18.
Correct Answer: A
Rationale: To solve for x in the equation 3(x - 4) = 18, first distribute the 3: 3x - 12 = 18. Next, add 12 to both sides to isolate the variable: 3x = 30. Finally, divide by 3 to find x = 10. Choice A is correct because it correctly solves the equation step by step. Choices B, C, and D are incorrect as they do not follow the correct mathematical operations to solve for x.
Question 5 of 5
A set of integers can be classified as positive, negative, or zero. Which of the following statements about multiplying positive and negative integers is ALWAYS true?
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.
