HESI A2 Study Guide
HESI A2 STUDY GUIDE
Purpose of HESI A2
The HESI A2 exam is used by nursing schools to assess students' academic readiness for
their programs.
It covers various subjects like math, science, grammar, biology, and anatomy and
physiology.
Sections of HESI A2
The exam typically includes sections on math, reading comprehension, vocabulary,
grammar, biology, chemistry, and anatomy and physiology.
Each section tests different skills and knowledge relevant to nursing education.
BIOLOGY
Cell Structure
Cells are the basic units of life and can be prokaryotic or eukaryotic.
Prokaryotic cells lack a nucleus, while eukaryotic cells have a membrane-bound nucleus.
Genetics
Genetics is the study of genes, heredity, and genetic variation in living organisms.
It includes concepts like DNA, RNA, genetic mutations, and inheritance patterns.
,CHEMISTRY
Chemical Reactions
Chemical reactions involve the breaking and forming of chemical bonds between atoms.
They can be classified into different types like synthesis, decomposition, combustion, and
redox reactions.
Atomic Structure
Atoms are the basic units of matter and consist of protons, neutrons, and electrons.
The arrangement of these subatomic particles determines the properties of elements.
ANATOMY AND PHYSIOLOGY
Human Body Systems
The human body is composed of multiple systems like the skeletal, muscular, circulatory,
respiratory, digestive, and nervous systems.
Each system has specific functions and interactions with other systems.
Homeostasis
Homeostasis is the body's ability to maintain internal stability and balance despite
external changes.
It involves processes like temperature regulation, pH balance, and blood sugar control.
GRAMMAR
Parts of Speech
Grammar involves the study of parts of speech like nouns, verbs, adjectives, adverbs,
pronouns, prepositions, conjunctions, and interjections.
Each part of speech serves a specific grammatical function in sentences.
Sentence Structure
, Sentences are structured with elements like subjects, predicates, objects, clauses, and
phrases.
Understanding sentence structure is essential for constructing clear and coherent
sentences.
MATH
Basic Operations
Mathematics includes basic operations like addition, subtraction, multiplication, and
division.
These operations are fundamental for solving mathematical problems.
Algebra
Algebra involves the use of variables, equations, and formulas to solve mathematical
problems.
It includes concepts like linear equations, quadratic equations, and inequalities.
SCIENCE
Scientific Method
The scientific method is a systematic approach to conducting scientific research and
experiments.
It involves steps like making observations, forming hypotheses, conducting experiments,
and drawing conclusions.
Branches of Science
Science is divided into various branches like biology, chemistry, physics, astronomy,
geology, and environmental science.
Each branch focuses on specific aspects of the natural world.
