HESI A2 Math Practice Test 2023 Questions
Question 1 of 5
A patient's weight is measured as 75 kilograms. What is their weight in pounds?
Correct Answer: B
Rationale: To convert kilograms to pounds, you multiply by 2.2. In this case, 75 kg x 2.2 = 165 pounds. Therefore, the correct answer is B: 150 pounds. Choice A is incorrect as it is less than the actual conversion. Choices C and D are also incorrect as they are significantly lower than the correct conversion.
Question 2 of 5
Simplify the expression: -5 + (-8)
Correct Answer: A
Rationale: To simplify -5 + (-8), we first add the two numbers together. -5 + (-8) = -13. The negative sign in front of 8 indicates that the number is negative. Therefore, the correct answer is A: -13. Choice B (8) and Choice D (-5) are incorrect because they do not account for the negative sign in front of the 8. Choice C (13) is incorrect as it is the result of adding the absolute values of -5 and -8 without considering the negative sign.
Question 3 of 5
What is the result of dividing 4 7/8 by 1 1/6?
Correct Answer: A
Rationale: To divide mixed numbers, convert them to improper fractions. 4 7/8 = (8*4 + 7)/8 = 39/8 and 1 1/6 = (6*1 + 1)/6 = 7/6. Then divide 39/8 by 7/6: (39/8) ÷ (7/6) = (39/8) * (6/7) = 234/56 = 4 5/28 (Choice A). The other choices are incorrect because they do not yield the correct result when following the correct steps for dividing mixed numbers.
Question 4 of 5
The metric system of measurement was developed in France during Napoleon's reign. It is based on what multiplication factor?
Correct Answer: C
Rationale: The correct answer is C: 10. The metric system is based on multiples of 10, making conversions between units easy and logical. This factor allows for a systematic and uniform system of measurement, which is essential for scientific accuracy and global standardization. Choices A, B, and D are incorrect because the metric system is not based on the length of Napoleon's forearm, the number 2, or the atomic weight of helium. These options do not align with the foundational principles of the metric system, which is built on the decimal system for simplicity and consistency.

A patient's weight is measured as 75 kilograms. What is their weight in pounds?
Correct Answer: B
Rationale: To convert kilograms to pounds, you multiply by 2.2. In this case, 75 kg x 2.2 = 165 pounds. Therefore, the correct answer is B: 150 pounds. Choice A is incorrect as it is less than the actual conversion. Choices C and D are also incorrect as they are significantly lower than the correct conversion.
