HESI A2 Quizlet Math Questions
Question 1 of 5
The physician orders 60 mg of Augmentin; 80 mg/mL is on hand. How many milliliters will you give?
Correct Answer: C
Rationale: To determine the volume needed, divide the ordered dose by the concentration. 60 mg / 80 mg/mL = 0.75 mL. Choice C is correct as it correctly calculates the volume required. Choice A is incorrect as it is too low. Choice B is incorrect as it's also too low. Choice D is incorrect as it is too high.
Question 2 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.
Question 3 of 5
In a survey, 120 people were asked if they could swim. If 85% said they could, how many people could swim?
Correct Answer: B
Rationale: To find the number of people who can swim, multiply the total number of people surveyed by the percentage that can swim. In this case, 120 x 0.85 = 102. Choice B is correct. Choice A is too low as it doesn't account for the 85%. Choice C is too high. Choice D is also too low.
Question 4 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 5 of 5
If a parent changes their baby 6 times a day, how many diapers will be needed in a year?
Correct Answer: A
Rationale: To calculate the number of diapers needed in a year, we multiply the number of times the baby is changed per day (6) by the number of days in a year (365). So, 6 diapers/day x 365 days/year = 2190 diapers (Choice A). This is the correct answer as it accounts for daily changes throughout the year. Choices B, C, and D are incorrect because they do not accurately calculate the total number of diapers needed based on the given information.
