What is the HESI Exam & Calculator Policy?
The HESI (Health Education Systems, Inc.) exam is a suite of tests used by nursing schools and other healthcare programs to assess applicants’ academic readiness and predict their success in the program. The most common HESI exam for nursing school applicants is the HESI A2 (Admission Assessment), which typically covers sections like Math, Reading Comprehension, Vocabulary, Grammar, Biology, Chemistry, and Anatomy & Physiology.
A very common question is: **can I use a calculator on the HESI?** The answer is: **it depends**. There is no single universal rule for calculator use on all HESI exams.
- HESI A2 Exam:** Generally, for the Math section of the HESI A2, a basic on-screen calculator is provided within the testing software for certain problems or sections. However, some schools or testing centers may not allow any calculator, or only allow it for specific questions. You are usually NOT allowed to bring your own physical calculator. Always check with the specific school or testing center administering the HESI A2 exam for their exact calculator policy.
- HESI Exit Exams and Specialty Exams:** For HESI exams taken during or at the end of a nursing program (like Exit Exams or specialty exams), calculator policies can also vary. On-screen calculators are often available.
Common Misconceptions:** Many assume they can bring their own calculator or that one is always available. It’s crucial to verify the rules beforehand to avoid surprises on test day. The absence of a physical calculator is why practicing manual calculations is so important if you’re preparing for the HESI A2 Math section.
HESI A2 Math Section & Typical Calculations
The HESI A2 Math section assesses basic math skills relevant to healthcare, including:
- Fractions (addition, subtraction, multiplication, division)
- Decimals and Percentages
- Ratios, Proportions, and Rates
- Basic Algebra (solving for x)
- Measurement Conversions (Metric, Imperial/Household, Apothecary – though less common now)
- Roman Numerals
- Dosage Calculations (basic)
Even if an on-screen calculator is provided, it’s often very basic. Strong foundational math skills are essential. Our practice tool above focuses on unit conversions, a key area.
Unit Conversion Formulas:
The calculator uses standard conversion factors. For example:
- 1 meter (m) = 100 centimeters (cm)
- 1 kilogram (kg) = 1000 grams (g) = 2.20462 pounds (lb)
- 1 liter (L) = 1000 milliliters (mL)
- 1 inch (in) = 2.54 centimeters (cm)
- °F = (°C × 9/5) + 32
- °C = (°F – 32) × 5/9
When converting, you multiply or divide by the conversion factor, or use the temperature formulas.
| From | To | Multiply by/Formula |
|---|---|---|
| m | cm | 100 |
| cm | m | 0.01 |
| kg | g | 1000 |
| g | kg | 0.001 |
| L | mL | 1000 |
| mL | L | 0.001 |
| in | cm | 2.54 |
| cm | in | 1 / 2.54 |
| kg | lb | 2.20462 |
| lb | kg | 1 / 2.20462 |
| °C | °F | (°C × 9/5) + 32 |
| °F | °C | (°F – 32) × 5/9 |
Practical Examples (HESI Math Problems)
Here are examples similar to what you might see, often requiring manual calculation or a basic on-screen tool:
Example 1: Fraction Addition
A patient drinks 1/2 cup of water, then 1/3 cup of juice. How much liquid did the patient drink in total?
1/2 + 1/3 = 3/6 + 2/6 = 5/6 cup. You need to find a common denominator.
Example 2: Unit Conversion
A medication dose is 500 mg, and the tablets available are 0.25 g each. How many tablets are needed?
First, convert mg to g: 500 mg / 1000 mg/g = 0.5 g.
Then, divide the required dose by the tablet strength: 0.5 g / 0.25 g/tablet = 2 tablets.
Our calculator above can help you practice the 500 mg to 0.5 g conversion.
How to Use This HESI Math Practice Calculator
- Enter Value: Input the numerical value you want to convert in the “Value to Convert” field.
- Select ‘From Unit’: Choose the starting unit from the “From Unit” dropdown menu.
- Select ‘To Unit’: The “To Unit” dropdown will automatically populate with compatible units. Select the unit you want to convert to.
- View Result: The converted value will appear in the “Result” section, along with the conversion factor or formula used.
- Practice Regularly: Use this tool to get comfortable with common conversions you might encounter on the HESI, especially if you anticipate not having a calculator or only a basic one.
Key Factors That Affect HESI Calculator Use and Math Success
- Specific HESI Exam Version: The A2, Exit, and specialty exams might have different rules.
- Nursing School’s Policy: Each school can set its own guidelines for the HESI it administers.
- Testing Center Rules: Prometric or other testing centers have their own regulations.
- On-Screen Calculator Availability: If provided, it’s usually basic (four-function). Familiarize yourself with how it works if possible.
- Your Math Fundamentals: Regardless of calculator availability, strong basic math skills (fractions, decimals, percentages, conversions) are vital.
- Practice Without a Calculator: Since you might not have one, or only a basic one, practice solving problems manually. This is key for the HESI.
The most reliable way to know if **you can use a calculator on the HESI** is to check the official instructions provided by your nursing school or the testing institution for your specific exam session.
Frequently Asked Questions (FAQ) about HESI and Calculators
- Can I bring my own calculator to the HESI A2?
- Almost always, no. You cannot bring your own physical calculator into the testing room for the HESI A2. If a calculator is allowed, it will be provided on-screen.
- Is a calculator provided for the HESI A2 Math section?
- Often, a basic on-screen calculator is available for the math section, but this varies. Confirm with your testing provider. Don’t rely on it being available for all questions.
- What kind of calculator is provided, if any?
- If provided, it’s usually a simple, four-function digital calculator within the testing software.
- What if I don’t know if I can use a calculator on the HESI for my test?
- Contact your nursing school’s admissions office or the testing center directly well before your exam date. Do not wait until test day.
- Does the HESI Exit Exam allow calculators?
- Policies for the HESI Exit Exam can also vary, but an on-screen calculator is more commonly available than for the A2. Again, verify.
- How should I prepare for the HESI Math section if I’m unsure about calculator access?
- Prepare as if you will NOT have a calculator. Practice manual calculations for fractions, decimals, percentages, and conversions extensively. See our HESI Math practice tests.
- Are there specific HESI exams where calculators are definitely allowed or disallowed?
- It’s hard to give a definitive “always” or “never” as it depends on the institution. Assume “no” or “basic on-screen only” for the A2 unless told otherwise.
- Can I use a calculator on the HESI for dosage calculations?
- If an on-screen calculator is provided during the math section, you can use it for dosage calculation questions within that section. However, practice these manually too.
