HESI A2 Math Practice Exam Questions

Question 1 of 5

A clinic sees an average of 25 patients every 4 hours. If the clinic is open for 8 hours, how many patients will they see in total?

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.

Question 2 of 5

The physician ordered 10 units of regular insulin, and 200 U/mL are on hand. How many milliliters will you give?

Correct Answer: D

Rationale: The correct answer is D: .05 mL. To calculate the amount of insulin to administer, use the formula: Amount of insulin (mL) = Required units / Concentration of insulin (U/mL) Plugging in the values: Amount of insulin (mL) = 10 units / 200 U/mL = 0.05 mL Therefore, you would administer 0.05 mL of insulin. Choice A (.45 mL), B (.75 mL), and C (.25 mL) are incorrect as they do not align with the calculated value of 0.05 mL based on the given concentration and the required units of insulin.

Question 3 of 5

How many centimeters are in a foot?

Correct Answer: C

Rationale: The correct answer is C: 30.48 cm. The conversion factor for feet to centimeters is 1 foot = 30.48 cm. To convert feet to centimeters, you multiply the number of feet by 30.48. Therefore, there are 30.48 cm in a foot. Choice A (30 cm) and Choice B (31.5 cm) are incorrect because they do not accurately represent the conversion factor from feet to centimeters. Choice D (35 cm) is also incorrect because it is not the standard conversion factor for feet to centimeters. Be sure to use the correct conversion factor of 30.48 cm when converting between feet and centimeters.

Question 4 of 5

A hospital day staff consists of 25 registered nurses, 75 unlicensed assistants, 5 phlebotomists, 6 receptionists, and 45 physicians. On one particular day, the staff was at only 68% strength. How many people were working that day? (Round to the nearest whole number).

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.

Question 5 of 5

If Bill has 5.5 vacation days left for the rest of the year and 3.25 sick days left, how many days will he have off work if he uses all of this time?

Correct Answer: A

Rationale: To find the total days off work, we add Bill's remaining vacation days (5.5) and sick days (3.25). 5.5 + 3.25 = 8.75 Therefore, Bill will have 8.75 days off work if he uses all of his remaining vacation and sick days. Choice A (8.75) is correct because it accurately represents the total days off. Choices B, C, and D are incorrect as they do not correctly calculate the total days off based on the given information.
