HESI A2 Quizlet Math Questions

Question 1 of 5

If the elephant weighed 3 tons, how many pounds did it weigh?

Correct Answer: A

Rationale: To convert tons to pounds, you multiply the weight in tons by 2000 (since 1 ton = 2000 pounds). Therefore, 3 tons x 2000 = 6000 pounds. Choice A (6000 pounds) is correct. Choices B, C, and D are incorrect because they do not correctly convert 3 tons to pounds. B (5000 pounds) is too low, C (3000 pounds) is even lower, and D (7000 pounds) is too high.

Question 2 of 5

An IV drip delivers medication at a rate of 40 drops per minute. Each drop contains 0.05 milliliters of the medication. How many milliliters of medication are delivered in one hour?

Correct Answer: D

Rationale: To calculate the amount of medication delivered in one hour, first find the amount delivered in one minute: 40 drops/min * 0.05 mL/drop = 2 mL/min. Then, multiply by the number of minutes in an hour: 2 mL/min * 60 min = 120 mL. Therefore, the correct answer is D (120 milliliters). Summary: A: Incorrect. Not enough medication delivered. B: Incorrect. Not enough medication delivered. C: Incorrect. Too low of an amount delivered.

Question 3 of 5

What is the least common multiple (LCM) of 4 and 6?

Correct Answer: A

Rationale: To find the LCM of 4 and 6, identify the prime factors of each number: 4 = 2^2 and 6 = 2 * 3. The LCM includes all prime factors with the highest powers, so LCM(4, 6) = 2^2 * 3 = 12. Therefore, the correct answer is A (24), as it is the product of the prime factors 2^2 and 3, which is the least common multiple of 4 and 6. Choices B, C, and D are incorrect because they do not represent the correct combination of prime factors for the LCM of 4 and 6.

Question 4 of 5

Sarah had 1 quart of milk. How many ounces of milk is that?

Correct Answer: C

Rationale: To convert quarts to ounces, we know that 1 quart equals 32 ounces. This is because 1 quart = 32 fluid ounces. So, when Sarah has 1 quart of milk, she has 32 ounces. Therefore, the correct answer is C: 32 ounces. A: 16 ounces - Incorrect. 1 pint is equal to 16 ounces, not 1 quart. B: 24 ounces - Incorrect. There is no direct conversion relationship between quarts and 24 ounces. D: 48 ounces - Incorrect. 1 gallon is equivalent to 128 ounces, not 1 quart.

Question 5 of 5

How many meters are in 5 kilometers?

Correct Answer: B

Rationale: The correct answer is B: 5000. To convert kilometers to meters, you need to multiply by 1000 since there are 1000 meters in a kilometer. So, 5 kilometers x 1000 = 5000 meters. Choice A (1000) is the number of meters in 1 kilometer, not 5. Choice C (10000) is the result of multiplying 10 kilometers by 1000. Choice D (500) is incorrect as it is not the correct conversion from kilometers to meters.
