HESI A2 Math Practice Exam Questions

Question 1 of 5

What is 72 inches converted to feet?

Correct Answer: B

Rationale: To convert inches to feet, divide the number of inches by 12 since there are 12 inches in a foot. 72 inches divided by 12 equals 6 feet. Therefore, the correct answer is B: 6 feet. Choice A (12 feet) is incorrect as it is the conversion of 144 inches, not 72 inches. Choice C (4 feet) and Choice D (17 feet) are also incorrect as they do not accurately represent the conversion of 72 inches to feet.

Question 2 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 3 of 5

Jan canned 5 gallons of homemade tomatoes. She needs to purchase quart jars to finish the process. How many quart jars will she need to buy for her tomatoes?

Correct Answer: C

Rationale: To convert 5 gallons to quarts, we know that 1 gallon = 4 quarts. So, 5 gallons = 5 x 4 = 20 quarts. Since she needs quart jars, Jan will need to buy 20 quart jars to can her 5 gallons of homemade tomatoes. Choices A, B, and D are incorrect because they do not correctly convert gallons to quarts. Choice A (10) is half of the correct answer, choice B (15) is three-quarters, and choice D (25) is more than the actual amount needed.

Question 4 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 5 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.
