Understanding the HESI A2 Math Exam

The HESI A2 math section assesses your foundational mathematical skills essential for success in healthcare programs. The questions cover a range of topics, including basic arithmetic, algebra, geometry, and data interpretation. Unlike some standardized tests, the HESI A2 doesn't focus on complex calculus or advanced statistical analysis. Instead, it emphasizes practical application and problem-solving skills frequently encountered in a healthcare setting.

Key Topics Covered:

• Basic Arithmetic: This includes operations with whole numbers, fractions, decimals, and percentages. Expect questions on addition, subtraction, multiplication, division, order of operations (PEMDAS/BODMAS), and converting between fractions, decimals, and percentages.

• Algebra: This section tests your understanding of algebraic expressions, equations, and inequalities. You'll likely encounter problems involving solving for variables, simplifying expressions, and working with linear equations.

• Geometry: Expect basic geometry questions focusing on shapes such as rectangles, squares, triangles, and circles. Problems might involve calculating area, perimeter, volume, and understanding geometric relationships.

• Data Interpretation: This involves analyzing graphs, charts, and tables to extract information and answer questions. You need to be comfortable interpreting different data representations like bar graphs, pie charts, and line graphs.

• Ratio and Proportion: Solving problems involving ratios and proportions is a crucial skill tested on the HESI A2. This involves understanding the relationship between different quantities and using proportions to solve for unknowns.

Effective Study Strategies for HESI A2 Math

Effective preparation is key to acing the HESI A2 math exam. Here's a structured approach to maximize your study time:

1. Assess Your Strengths and Weaknesses: Before you start studying, take a diagnostic practice test to identify areas where you need the most improvement. This will allow you to focus your efforts efficiently.

2. Review Fundamental Concepts: Ensure you have a strong grasp of the basic arithmetic principles mentioned above. If you find yourself struggling with fractions, decimals, or percentages, dedicate extra time to mastering these concepts. Utilize online resources, textbooks, or tutoring if needed.

3. Practice Regularly: Consistent practice is crucial. Work through numerous practice problems, focusing on areas where you need more improvement. Don't just solve problems; analyze your mistakes and understand the underlying concepts.

4. Use Practice Exams: Practice exams are invaluable for simulating the actual test environment and getting used to the question format and time constraints. These exams help you identify your weak areas and improve your time management skills.

5. Seek Help When Needed: If you're struggling with a particular concept, don't hesitate to seek help. Utilize online resources, textbooks, or consider seeking tutoring assistance. Understanding the underlying principles is more important than memorizing formulas.

6. Time Management: Practice solving problems under timed conditions. The HESI A2 has a time limit, so you need to be able to solve problems efficiently. Allocate your time strategically during the exam, focusing on the questions you find easier first.

7. Focus on Application: The HESI A2 emphasizes practical application. Focus on understanding how to apply mathematical concepts to real-world scenarios, particularly those relevant to healthcare.

HESI A2 Math Practice Problems & Solutions

Let's work through some sample problems covering different key topics. Remember to try solving these problems independently before reviewing the solutions.

Problem 1: Basic Arithmetic

A nurse administers 0.75 liters of saline solution to a patient. If the solution is divided equally into three doses, how many milliliters are in each dose? (Note: 1 liter = 1000 milliliters)

Solution:

1. Convert liters to milliliters: 0.75 liters * 1000 milliliters/liter = 750 milliliters.
2. Divide by the number of doses: 750 milliliters / 3 doses = 250 milliliters/dose.

Answer: Each dose contains 250 milliliters.

Problem 2: Algebra

A patient's weight increased by 15% over the past year. If their current weight is 184 pounds, what was their weight a year ago?

Solution:

Let x be the weight a year ago. The current weight is 1.15x (100% + 15% = 115% = 1.15).

1.15x = 184 x = 184 / 1.15 x ≈ 160

Answer: Their weight a year ago was approximately 160 pounds.

Problem 3: Geometry

A rectangular bandage measures 10 centimeters by 5 centimeters. What is its area in square centimeters?

Solution:

Area of a rectangle = length * width = 10 cm * 5 cm = 50 square centimeters.

Answer: The area is 50 square centimeters.

Problem 4: Data Interpretation

A pie chart shows the distribution of patients based on their blood type. If the chart shows that 40% of patients have blood type O, and there are a total of 200 patients, how many have blood type O?

Solution:

Number of patients with blood type O = 40% of 200 = 0.40 * 200 = 80 patients.

Answer: 80 patients have blood type O.

Problem 5: Ratio and Proportion

A pharmacist needs to mix a solution with a ratio of 2 parts medicine to 5 parts water. If they use 12 parts of medicine, how many parts of water are needed?

Solution:

Set up a proportion: 2/5 = 12/x

Cross-multiply: 2x = 60 x = 30

Answer: 30 parts of water are needed.

Frequently Asked Questions (FAQs)

Q: What type of calculator can I use on the HESI A2 math exam?

A: The specific calculator policy varies depending on the testing center. Some centers allow basic calculators; others might only permit on-screen calculators provided during the exam. It's crucial to check with your testing center beforehand to confirm the permitted calculator type.

Q: How many questions are on the HESI A2 math section?

A: The number of questions can vary slightly depending on the version of the exam. However, it generally contains a significant number of questions, typically ranging from 25 to 50, focusing on the fundamental mathematical concepts previously discussed.

Q: How much time do I have to complete the math section?
