Below is a comprehensive HESI A2 Version 2 practice test with 300 questions covering all
seven sections. Each question includes the correct answer in bold and a brief rationale
in italics. This reflects the actual HESI A2 exam format .
📖 SECTION 1: READING COMPREHENSION (45 Questions)
Passage 1: The Water Cycle
Water is essential for all life on Earth. The water cycle, also known as the hydrological
cycle, describes the continuous movement of water on, above, and below the surface of the
Earth. Water changes state between liquid, vapor, and ice through various processes.
Evaporation occurs when water transforms from liquid to gas, primarily from oceans and
lakes. Condensation is the process by which water vapor becomes liquid droplets, forming
clouds. Precipitation returns water from clouds to Earth as rain, snow, sleet, or hail. Runoff
carries water from land back to oceans and lakes, completing the cycle.
1. What is the main idea of this passage?
A) Oceans are the largest source of water
B) The water cycle describes the continuous movement of water
C) Precipitation only occurs as rain
D) Water never changes state
Answer: B
Rationale: The passage explicitly states the water cycle describes continuous movement of
water on, above, and below Earth's surface.
2. According to the passage, evaporation occurs primarily from:
A) Clouds
B) Rivers and streams
C) Oceans and lakes
,D) Underground aquifers
Answer: C
Rationale: The passage states evaporation occurs "primarily from oceans and lakes."
3. What is condensation?
A) Water turning into gas
B) Water vapor becoming liquid droplets
C) Rain falling from clouds
D) Water freezing into ice
Answer: B
Rationale: The passage defines condensation as "water vapor becomes liquid droplets,
forming clouds."
4. Which of the following is NOT mentioned as a form of precipitation?
A) Rain
B) Snow
C) Hail
D) Fog
Answer: D
Rationale: The passage lists rain, snow, sleet, and hail. Fog is not mentioned as
precipitation.
5. What completes the water cycle?
A) Evaporation
B) Condensation
C) Runoff carrying water back to oceans and lakes
D) Cloud formation
Answer: C
Rationale: The passage states "runoff carries water from land back to oceans and lakes,
completing the cycle."
Passage 2: The Digestive System
The digestive system breaks down food into nutrients that the body can absorb. Digestion
begins in the mouth, where teeth chew food and saliva begins breaking down
carbohydrates. The esophagus transports food to the stomach using muscular contractions
called peristalsis. In the stomach, gastric juices containing hydrochloric acid and enzymes
break down proteins. The small intestine is where most nutrient absorption occurs. The
large intestine absorbs water and electrolytes before eliminating waste.
,6. Where does digestion begin?
A) Stomach
B) Small intestine
C) Mouth
D) Esophagus
Answer: C
Rationale: The passage states "digestion begins in the mouth."
7. What is peristalsis?
A) Chewing food
B) Muscular contractions that transport food
C) Release of gastric juices
D) Absorption of nutrients
Answer: B
Rationale: The passage defines peristalsis as "muscular contractions" that transport food
from esophagus to stomach.
8. Where does most nutrient absorption occur?
A) Stomach
B) Large intestine
C) Small intestine
D) Esophagus
Answer: C
Rationale: The passage explicitly states "the small intestine is where most nutrient
absorption occurs."
9. Gastric juices contain:
A) Only water
B) Hydrochloric acid and enzymes
C) Bile and pancreatic juice
D) Only enzymes
Answer: B
Rationale: The passage states gastric juices contain "hydrochloric acid and enzymes."
10. What does the large intestine absorb?
A) Proteins and carbohydrates
B) Only water
C) Water and electrolytes
D) Fats and vitamins
, Answer: C
Rationale: The passage states the large intestine "absorbs water and electrolytes."
Passage 3: The Solar System
Our solar system consists of the Sun and eight planets. The four inner planets—Mercury,
Venus, Earth, and Mars—are terrestrial, meaning they have rocky surfaces. The four outer
planets—Jupiter, Saturn, Uranus, and Neptune—are gas giants, composed primarily of
hydrogen and helium, except Uranus and Neptune which are sometimes called ice giants.
Jupiter is the largest planet, while Mercury is the smallest. Earth is the only planet known to
support life.
11. How many planets are in our solar system according to the passage?
A) Seven
B) Eight
C) Nine
D) Ten
Answer: B
Rationale: The passage states "eight planets."
12. Which planets are described as terrestrial?
A) Jupiter, Saturn, Uranus, Neptune
B) Mercury, Venus, Earth, Mars
C) Earth and Mars only
D) Venus and Earth only
Answer: B
Rationale: The passage lists Mercury, Venus, Earth, and Mars as the four inner terrestrial
planets.
13. What is the largest planet?
A) Saturn
B) Jupiter
C) Earth
D) Neptune
Answer: B
Rationale: The passage states "Jupiter is the largest planet."
14. Which planet is the smallest?
A) Mars
B) Venus
