HESI A2 Math Practice Exam

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: B

Rationale: To find the total number of staff working, calculate 68% of the total staff. Total staff = 25 (RN) + 75 (assistants) + 5 (phlebotomists) + 6 (receptionists) + 45 (physicians) = 156 68% of 156 = 0.68 x 156 = 106.08 Rounded to the nearest whole number, the total staff working that day is 106. Therefore, the correct answer is B: 106. Summary: A: 102 - Incorrect, not the nearest whole number. C: 98 - Incorrect, below the calculated total. D: 110 - Incorrect, above the calculated total.

Correct Answer: B

Rationale: To find the total number of games played, we divide the number of games won (72) by the percentage of games won (90%). This gives us 72 / 0.90 = 80 games played. Therefore, choice B is correct. Choice A (75) is incorrect because it does not account for the percentage of games won. Choice C (85) is incorrect as it overestimates the total number of games played. Choice D (100) is incorrect as it does not reflect the fact that the team won only 90% of the games played.

Correct Answer: D

Rationale: To convert 45 kg to pounds, we use the conversion factor 1 kg = 2.20462 pounds. So, 45 kg * 2.20462 pounds/kg = 99.2079 pounds, which rounds to 110 pounds. Therefore, the correct answer is D. Choice A (10 pounds) is incorrect as it is much lower than the actual conversion. Choice B (100 pounds) is close but slightly lower than the accurate value. Choice C (1,000 pounds) is significantly higher and not a reasonable conversion for 45 kg.

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.
