Overview of HESI A2 Mathematics Exam
Purpose and Structure
The HESI A2 Mathematics exam assesses mathematical skills necessary for nursing and health science programs.
It consists of 38 questions covering various mathematical concepts including ratios, proportions, conversions, and basic
arithmetic operations.
The exam is timed, and students must manage their time effectively to complete all questions.
Key Mathematical Concepts
Ratios and Proportions: Understanding how to set up and solve ratios is crucial for many questions.
Conversions: Familiarity with converting units (e.g., milliliters to liters, ounces to pints) is essential.
Basic Arithmetic: Mastery of addition, subtraction, multiplication, and division is fundamental.
Detailed Problem Types
Ratios and Proportions
Example Problem: 15:1000::x:100. To find x, cross-multiply and solve for x: x = (15 * 100) / 1000 = 1.5.
Understanding how to express ratios in different forms (e.g., fractions, decimals) is important for solving problems.
Common ratio problems may involve real-life scenarios such as mixing solutions or calculating dosages.
Unit Conversions
Example Problem: How many liters are in 300 milliliters? (Answer: 0.3 liters)
Familiarize yourself with common conversions: 1 liter = 1000 milliliters, 1 pint = 16 ounces, etc.
Practice converting between metric and imperial units, as this is frequently tested.
Sample Questions and Solutions
,Example Questions
1. Question: How many ounces are in 8 1/4 pints?
Solution: 8.25 pints * 16 oz/pint = 132 oz (Answer: A)
2. Question: What is the result of dividing 0.9 by 3?
Solution: 0. = 0.3 (Answer: C)
Problem-Solving Strategies
Always read the question carefully to understand what is being asked before attempting to solve it.
Use estimation to quickly eliminate obviously incorrect answers, especially in multiple-choice questions.
Write down any formulas or conversion factors you may need to use for calculations.
Practice Problems
Additional Practice Questions
1. Convert 11:32 A.M. to Military time. (Answer: A. 1132)
2. How many grams are in 4 kilograms? (Answer: B. 4000)
3. If a label states that 1 mil contains 500 mg, how many grams are there if there are 1.5 mils? (Answer: A. 0.75 grams)
Solutions to Practice Problems
Question 1: 11:32 A.M. in military time is 1132.
Question 2: 4 kg = 4000 grams (since 1 kg = 1000 grams).
Question 3: 1.5 mils * 500 mg/mil = 750 mg = 0.75 grams.
,HESI A2 Math Practice Test
QUESTION 1 OF 17
A patient has a 45-day prescription for a medication.
If they have taken the medication for 16 days how many days of the prescription
are left? ______________ (Enter numerical values only)
Answer: 29
This problem can be solved by subtracting the days that have passed (16) from the total
days called for by the prescription (45).
Step 1: Set up long subtraction:
Step 2: Since 5 is less than 6, borrow 1 from the next column. 5 becomes 15 and 4
becomes 3.
Step 3: Calculate 15 – 6 = 9
Step 4: Calculate 3 – 1 = 2
Answer: 29
, QUESTION 2 OF 17
Convert to military time: 4:25:20 P.M.
2025:20 hours
1325:20 hours
1604:20 hours
1625:20 hours
Answer: 1625:20 hours
Step 1: Since the time is P.M., we need to add 12 to obtain the hours.
4 + 12 = 16
Step 2: Write as military time. Note that military time has a colon (:) separating minutes and
seconds only.
1625:20 hours.
