HESI A2 Math Practice Exam Questions

Question 1 of 5

The physician ordered 20 mg of Tylenol per kg of body weight; on hand is 80 mg per tablet. The child weighs 12 kg. How many tablets will you give?

Correct Answer: B

Rationale: To calculate the number of tablets needed, first, find the total Tylenol dosage needed for the child: 20 mg/kg * 12 kg = 240 mg. Then, divide the total dosage needed by the dosage per tablet: 240 mg / 80 mg = 3 tablets. Therefore, the correct answer is B (3 tablets). Choice A is incorrect because 1 tablet is not sufficient to meet the required dosage. Choices C and D are incorrect as they do not match the calculated amount needed based on the child's weight and the dosage per tablet.

Question 2 of 5

The physician ordered 3,000 units of heparin; 5,000 U/mL is on hand. How many milliliters will you give?

Correct Answer: B

Rationale: To calculate the volume needed, use the formula: Volume (ml) = Required dose (units) / Concentration (U/ml). In this case, Volume = 3,000 units / 5,000 U/ml = 0.6 ml. Therefore, the correct answer is B (0.6 ml). Choice A is incorrect because it underestimates the volume needed. Choices C and D are incorrect as they overestimate the volume required based on the calculation.

Question 3 of 5

If a dozen roses cost $36, how much will four roses cost?

Correct Answer: B

Rationale: To find the cost of 4 roses, we divide the total cost of 12 roses by 12 to get the cost of 1 rose ($36 / 12 = $3). Then, we multiply the cost of 1 rose by 4 to find the cost of 4 roses ($3 * 4 = $12). Therefore, the correct answer is B. Choice A ($9) is incorrect as it assumes a linear relationship between the number of roses and the cost, which is not the case. Choice C ($10) and Choice D ($15) are also incorrect as they do not follow the correct calculation method.

Question 4 of 5

How many millimeters are in 5 meters?

Correct Answer: A

Rationale: To convert meters to millimeters, we know that 1 meter is equal to 1000 millimeters. Therefore, to find how many millimeters are in 5 meters, we multiply 5 by 1000 which equals 5000 millimeters. Choice A (5000 mm) is correct. Choices B, C, and D are incorrect as they do not accurately convert 5 meters to millimeters. Choice B (4000 mm) is incorrect because it underestimates the conversion. Choice C (5500 mm) is incorrect as it overestimates the conversion. Choice D (6000 mm) is also incorrect as it overestimates the conversion.

Question 5 of 5

What is 2/3 of 60 + 1/5 of 75?

Correct Answer: B

Rationale: To find 2/3 of 60, multiply 60 by 2/3, which gives 40. Next, find 1/5 of 75 by multiplying 75 by 1/5, which equals 15. Adding 40 and 15 gives us 55. Therefore, the correct answer is B (55). Choice A (45) is incorrect as it only considers 2/3 of 60 without adding 1/5 of 75. Choices C (15) and D (50) also do not account for both parts of the equation.
