HESI A2 Math Practice Exam

Correct Answer: B

Rationale: To find the percentage of band members who missed practice, we need to calculate the ratio of band members who missed practice to the total band members. 9 out of 75 band members missed practice, so the ratio is 9/75 = 0.12 or 12%. Therefore, the correct answer is B (12%). Choice A (10%) is incorrect as 9 out of 75 is not equivalent to 10%. Choice C (15%) is incorrect as 9 out of 75 is not equivalent to 15%. Choice D (18%) is incorrect as 9 out of 75 is not equivalent to 18%.

Correct Answer: A

Rationale: To convert meters to millimeters, we know that 1 meter is equal to 1000 millimeters. Therefore, to find how many millimeters are in 5 meters, we multiply 5 by 1000 which equals 5000 millimeters. Choice A (5000 mm) is correct. Choices B, C, and D are incorrect as they do not accurately convert 5 meters to millimeters. Choice B (4000 mm) is incorrect because it underestimates the conversion. Choice C (5500 mm) is incorrect as it overestimates the conversion. Choice D (6000 mm) is also incorrect as it overestimates the conversion.

Correct Answer: C

Rationale: The correct answer is C (Early afternoon to bedtime) because working from 1300 to 2000 corresponds to the time frame of early afternoon to bedtime. 1300 is 1:00 PM in the afternoon, and 2000 is 8:00 PM in the evening. This aligns with the early afternoon to evening shift. Incorrect choices: A: Early morning to early afternoon - This is incorrect as the healthcare professional's shift starts in the afternoon, not the early morning. B: Lunchtime to midnight - This is incorrect as the shift ends at 8:00 PM, not midnight. D: Midnight to sunrise - This is incorrect as the shift starts in the afternoon, not at midnight.

Correct Answer: A

Rationale: To calculate the nurse's take-home pay, we need to first calculate the total earnings for the week: Total earnings = (Hourly rate x total hours) = ($17.81 x (3 x 8 + 1 x 12)) = $17.81 x 36 = $641.16. Then deduct the total deductions for the week: Total deductions = Federal tax + State tax + Federal insurance + Family health insurance = $102.80 + $24.58 + $18.13 + $52.15 = $197.66. Finally, calculate the nurse's take-home pay: Take-home pay = Total earnings - Total deductions = $641.16 - $197.66 = $443.50. Therefore, the correct answer is A: $443.50, as it accurately reflects the nurse's take-home pay after all deductions. Option B, C, and D are incorrect as they do not reflect the accurate calculations based on the given information.

Correct Answer: A

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. 56 ÷ 16 = 3.5 pints. So, the correct answer is A: 3.5 pints. Choices B, C, and D are incorrect because they do not accurately represent the conversion of 56 ounces to pints based on the conversion factor of 1 pint = 16 ounces.
