HESI A2 Math Practice Test 2023 Questions
Question 1 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.
Question 2 of 5
A newborn weighs 3,459 grams. There are 453.59 grams per pound. What is the infant's weight in pounds and ounces?
Correct Answer: A
Rationale: To convert the infant's weight from grams to pounds, divide 3,459 by 453.59 to get approximately 7.63 pounds. Since 1 pound is equal to 16 ounces, multiply the decimal part (.63) by 16 to get 10.08 ounces. Therefore, the infant's weight is 7 pounds and 10 ounces, making choice A the correct answer. Choices B, C, and D are incorrect due to incorrect conversions or calculations. B and C have the pound and ounce values switched, and D incorrectly converts the weight to 3 pounds and 13 ounces.
Question 3 of 5
How many ounces are in 4 quarts?
Correct Answer: B
Rationale: To convert quarts to ounces, we know that 1 quart is equal to 32 ounces. Therefore, to find out how many ounces are in 4 quarts, we multiply 4 (quarts) by 32 (ounces/quart), which equals 128 ounces. Thus, the correct answer is B: 128 ounces. A: 64 ounces - Incorrect, this is the equivalent of 2 quarts, not 4. C: 32 ounces - Incorrect, this is the equivalent of 1 quart, not 4. D: 16 ounces - Incorrect, this is half the amount of 1 quart, not 4.
Question 4 of 5
What is the probability of getting a 1 on a six-sided die?
Correct Answer: A
Rationale: The correct answer is A: 1/6. The probability of getting a 1 on a six-sided die is calculated by dividing the number of favorable outcomes (rolling a 1) by the total number of possible outcomes (6 sides on the die). Since there is only 1 side with a 1, the probability is 1/6. Choice B (1/4) is incorrect as it represents the probability of rolling a 1 on a four-sided die, which only has 4 sides. Choice C (1/3) is incorrect as it represents the probability of rolling a 1 on a three-sided die, which is not a standard die. Choice D (1/2) is incorrect as it represents the probability of rolling a 1 on a two-sided die, which is not a standard die.
Question 5 of 5
How many inches are in 1.5 yards?
Correct Answer: A
Rationale: To convert yards to inches, you need to know that 1 yard is equal to 36 inches. Therefore, 1.5 yards is 1.5 x 36 = 54 inches. The correct answer is A (54 inches). Choice B (60 inches) is incorrect because it does not accurately convert 1.5 yards to inches. Choices C (72 inches) and D (84 inches) are also incorrect as they do not reflect the correct conversion.
