HESI A2 Math Practice Exam

Correct Answer: A

Rationale: To find the number of days to use 500 labels, first calculate the total labels used daily: 25 boxes/day * 3 labels/box = 75 labels/day. Then, divide the total labels (500) by labels used per day (75): 500 / 75 = 6.67 days. Since we need to round to the nearest whole number, it will take 7 days (Answer A) to use up the inventory. Choice B is incorrect as it doesn't account for rounding. Choice C is incorrect as it overestimates the number of days. Choice D is incorrect as it underestimates the number of days.

Correct Answer: A

Rationale: To find the weight of a 7 lb. baby in grams, multiply 7 (lbs) by the conversion factor 453.59 (grams/lb). 7 lbs x 453.59 = 3175.13 grams. Therefore, the correct answer is A. Choice B (4000 grams) is incorrect as it does not consider the precise conversion factor. Choice C (4535 grams) is incorrect as it simply multiplies 7 by 1000. Choice D (3500 grams) is incorrect as it uses a different conversion factor.

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 find the total number of patients seen in 8 hours, first calculate the number of patients seen in 1 hour (25/4 = 6.25). Then, multiply by 8 to get the total (6.25 * 8 = 50). Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not follow the correct calculation process. A, B, and C do not consider the rate of patients seen per hour or the total hours the clinic is open.

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.
