HESI A2 Math Practice Exam

Correct Answer: C

Rationale: To convert miles to feet, you need to multiply the number of miles by 5280 (the number of feet in a mile). Therefore, to find how many feet are in 2 miles, you would do 2 x 5280 = 10560 feet. This makes choice C the correct answer. Choices A, B, and D are incorrect because they do not use the correct conversion factor of 5280 feet per mile. Option A is the number of feet in 1 mile, option B and D are incorrect values that do not correspond to the conversion of miles to feet.

Correct Answer: B

Rationale: To calculate the number of tablets needed: 1. Determine the total dosage needed: 16 mg/kg x 15 kg = 240 mg. 2. Divide the total dosage by the dosage per tablet: 240 mg ÷ 80 mg = 3 tablets. 3. The correct answer is B (2 tablets) as it is the nearest whole number to the calculated 3 tablets. Choice A is incorrect because it is less than the calculated amount. Choice C is incorrect as it is less than the required dosage. Choice D is incorrect as it is a non-integer value.

Correct Answer: A

Rationale: The correct answer is A because to determine the highest average systolic pressure, you need to find the largest number in the "systolic pressure" column. This is because the average is calculated based on all the values in the column, and the highest number will have the most significant impact on the average. By finding the largest number, you ensure that the highest average systolic pressure is accurately identified. Option B is incorrect because comparing the means of each age group does not specifically pinpoint the highest average systolic pressure. Option C is incorrect as it calculates the overall average rather than focusing on the highest value. Option D is incorrect as subtracting the lowest from the highest does not give the highest average systolic pressure.
