HESI A2 Math Practice Test 2024 Questions
Question 1 of 5
Convert the following military time to regular time: 15:17:52.
Correct Answer: B
Rationale:
To convert military time to regular time, subtract 12 from the hours if it is 13 or greater. In this case, 15:17:52 becomes 3:17:52 PM.
Choice A (2:17 PM) is incorrect as it doesn't adjust for the 12-hour conversion.
Choice C (5:17 AM) and
Choice D (9:17 AM) are incorrect as they don't reflect the correct conversion from military time to regular time.
Question 2 of 5
Convert 2100 to standard time.
Correct Answer: C
Rationale: Military time is based on a 24-hour clock.
To convert 2100 hours to standard time, subtract 1200 from the time if it is greater than or equal to 1300. In this case, 2100 - 1200 = 900, which corresponds to 9:00 PM in standard time.
Choice A, 12:00 PM, is incorrect because 2100 is in the evening, not noon.
Choice B, 2:00 AM, is incorrect as it represents the early morning hours.
Choice D, 2:00 PM, is incorrect as it is in the afternoon, not the evening.
Question 3 of 5
A nurse is reviewing the daily intake and output (I&O) of a patient consuming a clear diet. The drainage bag denotes a total of 1,000 mL for the past 24 hours. The total intake is: 2 8oz cups of coffee, 1 16-oz serving of clear soup, and 1 pint of water consumed throughout the day. How much is the deficit in milliliters?
Correct Answer: A
Rationale: First, convert all fluid intake to milliliters:
2 8-oz cups of coffee = 8 2 30 = 480 mL
1 16-oz serving of clear soup = 16 30 = 480 mL
1 pint of water = 16 30 = 480 mL
Total intake = 480 + 480 + 480 = 1440 mL.
The patient produced 1,000 mL, so the deficit is:
1440 mL - 1000 mL = 440 mL.
Therefore, the deficit in milliliters is 440 mL.
Choice A is correct.
Choices B, C, and D are incorrect as they do not reflect the accurate deficit calculated based on the total intake and output provided in the question.
Question 4 of 5
A seamstress is measuring a model for a new dress. The tape measure is marked in centimeters. The seamstress needs to convert that measurement into inches. If the model's waist measurement is 65.4 centimeters, what is that in inches?
Correct Answer: A
Rationale:
To convert centimeters to inches, divide the measurement in centimeters by 2.54 (since 1 inch = 2.54 cm).
Therefore, 65.4 cm · 2.54 = 25.74 inches. This means that the model's waist measurement of 65.4 centimeters is equivalent to 25.74 inches.
Choices B, C, and D are incorrect as they do not result from the correct conversion calculation.
Question 5 of 5
Solve for x. x/250 = 3/500
Correct Answer: A
Rationale:
To solve the proportion x/250 = 3/500, cross multiply to get 500x = 750.
Then solve for x by dividing both sides by 500, which results in x = 1.5.
Therefore, the correct answer is A.
Choice B (2) is incorrect because the correct solution is 1.5, not 2.
Choice C (1500) is incorrect as it does not align with the correct calculation of the proportion.
Choice D (25) is incorrect and does not match the correct solution obtained by solving the proportion.
