HESI A2 Practice Test Math Questions

Question 1 of 5

Which of these percentages equals 1.25?

Correct Answer: D

Rationale: To find which percentage equals 1.25, we convert 1.25 to a percentage by multiplying it by 100. 1.25 * 100 = 125%. Therefore, the correct choice is D. Choice A (1250%) is incorrect as it represents 12.5, not 1.25. Choices B (25%) and C (50%) are also incorrect as they are significantly lower than 1.25.

Question 2 of 5

A patient needs to take 2 tablets for every 30 pounds of body weight. If they weigh 150 pounds, how many tablets should they take?

Correct Answer: B

Rationale: To calculate the number of tablets needed, we divide the patient's weight by 30 (150/30 = 5). Then, we multiply the result by 2 since they need 2 tablets per 30 pounds (5 x 2 = 10). Therefore, the correct answer is B (10 tablets). Choice A is incorrect as it does not account for the weight calculation. Choices C and D are incorrect as they do not consider the dosage requirement based on the patient's weight.

Question 3 of 5

How many pints are in 56 ounces?

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.

Question 4 of 5

What is 20% of 150?

Correct Answer: B

Rationale: To find 20% of 150, you multiply 150 by 20% (or 0.20). So, 150 * 0.20 = 30. Therefore, the correct answer is B (30). Choice A (25) is incorrect because 20% of 150 is not 25. Choice C (35) is incorrect because it is more than 20% of 150. Choice D (20) is incorrect because 20% of 150 is not the same as the original number 150.

Question 5 of 5

A lab test result shows a blood glucose level of 5.5 millimoles per liter (mmol/L). What is the equivalent level in milligrams per deciliter (mg/dL)?

Correct Answer: A

Rationale: The correct answer is A: 55 mg/dL. To convert from mmol/L to mg/dL for glucose, you multiply by 18. Therefore, 5.5 mmol/L x 18 = 99 mg/dL. However, blood glucose levels are commonly approximated by dividing by 2, so 99 mg/dL ≈ 50 mg/dL. Therefore, the closest option is A: 55 mg/dL. Option B (5.5 mg/dL) is incorrect as it does not account for the conversion factor of 18. Option C (0.55 mg/dL) is incorrect as it is a decimal point off from the correct answer. Option D (550 mg/dL) is incorrect as it is a factor of 10 too high.
