HESI A2
HESI A2 Math Practice Exam Questions
Question 1 of 5
What is the boiling point of water?
Correct Answer: A
Rationale: Failed to generate a rationale after 5 retries.
Question 2 of 5
What is the average of the numbers 14, 73, and 7?
Correct Answer: D
Rationale: To find the average of a set of numbers, you add them up and then divide by the total number of values. In this case, 14 + 73 + 7 = 94. Then, 94 divided by 3 (total numbers) gives 31.33. Therefore, choice D is correct. Choices A, B, and C are incorrect because they do not correctly calculate the average of the given numbers. A, B, and C are calculated as 14 + 73 + 7 divided by 3, which leads to incorrect averages.
Question 3 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 4 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 5 of 5
A table shows the average blood pressure readings for different age groups. How do you determine the highest average systolic pressure?
Correct Answer: A
Rationale: The correct answer is A because to determine the highest average systolic pressure, you need to find the largest number in the "systolic pressure" column. This is because the average is calculated based on all the values in the column, and the highest number will have the most significant impact on the average. By finding the largest number, you ensure that the highest average systolic pressure is accurately identified. Option B is incorrect because comparing the means of each age group does not specifically pinpoint the highest average systolic pressure. Option C is incorrect as it calculates the overall average rather than focusing on the highest value. Option D is incorrect as subtracting the lowest from the highest does not give the highest average systolic pressure.
