HESI A2 Math Practice Exam

Correct Answer: B

Rationale: To calculate the number of tablets needed: 1. Determine the total dosage needed: 16 mg/kg x 15 kg = 240 mg. 2. Divide the total dosage by the dosage per tablet: 240 mg ÷ 80 mg = 3 tablets. 3. The correct answer is B (2 tablets) as it is the nearest whole number to the calculated 3 tablets. Choice A is incorrect because it is less than the calculated amount. Choice C is incorrect as it is less than the required dosage. Choice D is incorrect as it is a non-integer value.

Correct Answer: B

Rationale: To find the total number of games played, we divide the number of games won (72) by the percentage of games won (90%). This gives us 72 / 0.90 = 80 games played. Therefore, choice B is correct. Choice A (75) is incorrect because it does not account for the percentage of games won. Choice C (85) is incorrect as it overestimates the total number of games played. Choice D (100) is incorrect as it does not reflect the fact that the team won only 90% of the games played.

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: B

Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, 3 pints would be 3 x 16 = 48 ounces. This makes choice B the correct answer. Choice A (24 ounces) is incorrect as it represents only 1 pint, not 3. Choice C (32 ounces) and choice D (64 ounces) are also incorrect as they do not accurately reflect the conversion of pints to ounces.

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.
