Essential academic skill requirements covered for the HESI test for entry into Nursing School, all in 6 laminated pages. The HESI A2 is predictable and this aspect makes the test easier to study for since the same concepts are covered in every test using the same types of questions. However, many people have underestimated this test their first time around and had to take it again, do not be one of them. These 6 laminated pages are a guide to success. Nurses are some of the biggest fans of QuickStudy guides, so start your collection and get started on a new career.
6-page laminated guide includes:

• Mathematics
• Reading Comprehension
• Vocabulary
• Grammar
• Biology
• Chemistry
• Anatomy & Physiology
• Physics
  

Mathematics

Order of Operations

• Must be performed in the following order: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction EX: 4 × (3 + 2)² + 5 × 3 = 4 × (5)² + 5 × 3 = 4 × 25 + 5 × 3 = 100 + 15 = 115

Roman Numerals

Roman Numeral	Value
I	1
V	5
X	10
L	50
C	100
D	500
M	1,000

• Always arranged from greatest to least in value and combined to form numbers EX: DCLXVI = 500 + 100 + 50 + 10 + 5 + 1 = 666
• To avoid adding four of the same numeral in a row, subtraction is used. If a numeral with a smaller value is placed before a numeral with a larger value, the smaller number should be subtracted from the larger number EX: CDLIX = 500 – 100 + 50 + 10 – 1 = 459

Converting Military Time to Civilian Time

• If the number is less than twelve hundred, the time is a.m. EX: 1135 = 11:35 a.m.
• If the number is twelve hundred or greater, the time is p.m. EX: 1250 = 12:50 p.m.
• If the number is thirteen hundred or greater, subtract 1200 EX: 1622 = 4:22 p.m.

ENGLISH TO METRIC CONVERSIONS & VICE VERSA

• Centimeters to inches: Multiply by 0.394
• Inches to centimeters: Multiply by 2.54
• Kilograms to pounds: Multiply by 2.205
• Pounds to kilograms: Multiply by 0.454
• Celsius to Fahrenheit: ([°C] × 1.8) + 32 = [°F]
• Fahrenheit to Celsius: ([°F] – 32) ÷ 1.8 = [°C]

Multiplying Fractions

• Multiply the numerators, then multiply the denominators EX:

  1

  4

  ×

  12

  5

  =

  12

  20

  Because both the numerator and denominator are divisible by 4, divide both by 4:

  12

  20

  =

  3

  5

Dividing Fractions

• Write all numbers (including any whole numbers or mixed numbers) in fraction form EX:

  3

  7

  ÷

  1

  4

  =
  In this case, both numbers are already in fraction form
• Write the reciprocal of the second fraction (found by inverting/flipping the fraction so the...
