HESI A2 READING COMPREHENSION: QUESTIONS WITH RATIONALES
SECTION 1: MAIN IDEA & SUPPORTING DETAILS
Questions 1–40
Question 1
The main idea of a passage is best defined as:
A. The topic sentence of the first paragraph
B. The central point the author wants to convey
C. The most interesting fact in the text
D. The concluding statement of the final paragraph
Answer: B
Rationale: The main idea represents the overarching message or primary concept the author
intends to communicate throughout the passage. While it may appear in a topic or concluding
sentence, it is not confined to a single location and encompasses the entire text's purpose.
Question 2
Which of the following would be considered a supporting detail rather than the main idea?
A. The significance of climate change on global ecosystems
B. Rising temperatures cause polar ice caps to melt
C. Human activities impact the environment
D. Climate change presents unprecedented challenges
Answer: B
Rationale: This statement provides specific evidence that supports the broader main idea about
climate change's impact. Supporting details offer concrete examples, facts, or data that
substantiate the central claim of the passage.

Question 3
When identifying the main idea, which question should the reader ask?
A. What is the author's favorite topic?
B. What is the passage mostly about?
C. How many paragraphs are in the text?
D. Who published this article?
Answer: B
Rationale: Asking what the passage is mostly about helps readers distinguish between the
central theme and peripheral information. This question directs attention to the overarching
concept rather than minor details or structural elements.
Question 4
In a passage about the benefits of exercise, which sentence likely contains the main idea?
A. Running burns approximately 100 calories per mile
B. Regular physical activity improves cardiovascular health
C. Many people enjoy morning workouts
D. Exercise equipment can be expensive
Answer: B
Rationale: This statement presents a broad claim about exercise's benefits that can be
supported by specific details. The other options provide supporting evidence, personal
preferences, or tangential information rather than the central thesis.
Question 5
Supporting details in a passage serve which primary function?
A. To confuse the reader
B. To provide evidence and clarification
C. To lengthen the text
D. To introduce new topics
Answer: B
Rationale: Supporting details substantiate the main idea by offering facts, examples, and
explanations that clarify and reinforce the author's central point.

Passage: The Inflammatory Response
The inflammatory response is a protective process triggered by injury. During this response,
blood vessels dilate and become more permeable, allowing white blood cells to migrate to the
affected area. The four cardinal signs of inflammation are redness, heat, swelling, and pain.
Question 6
What is the primary purpose of the inflammatory response described in the passage?
A. To permanently repair damaged tissue within minutes
B. To prevent all types of infections from entering the body
C. To protect the body by initiating a localized response to injury
D. To increase carbon dioxide levels in the blood
Answer: C
Rationale: The passage states that inflammation is a "protective process" triggered by injury,
involving vessel dilation and white blood cell migration to the affected area. Option A is
incorrect because repair is not immediate or permanent; Option B is too absolute ("prevent
all"); Option D is unrelated to inflammation.
Question 7
In the inflammatory response passage, what does the word "permeable" most nearly mean?
A. Closed off
B. Allowing substances to pass through
C. Thick and rigid
D. Inflamed and painful
Answer: B
Rationale: The passage states vessels "dilate and become more permeable, allowing white
blood cells to migrate." In this context, permeable means allowing substances (like white blood
cells) to pass through.
Passage: Hand Hygiene
Proper hand hygiene remains the single most effective intervention for preventing pathogen
transmission in healthcare settings. Despite this knowledge, compliance rates among healthcare
workers remain suboptimal.

Question 8
According to the passage on hand hygiene, what is the most effective method for preventing
healthcare-associated infections?
A. Wearing sterile gloves at all times
B. Isolating all infected patients
C. Performing proper hand hygiene
D. Using strong disinfectants on surfaces
Answer: C
Rationale: The passage explicitly states that "proper hand hygiene remains the single most
effective intervention for preventing pathogen transmission." Options A, B, and D are not
mentioned as the most effective method.
Passage: The Rainforest
Tropical rainforests play a critical role in global climate regulation. Trees take in carbon dioxide
and give off oxygen, helping to moderate the planet's temperature. When these forests are cut
down, not only is this oxygen production reduced, but the stored carbon is released into the
atmosphere, contributing to global warming.
Question 9
Based on the rainforest passage, what is one consequence of cutting down trees?
A. Decreased oxygen production
B. Reduced global warming
C. Lower carbon dioxide levels
D. Increased rainfall in the Amazon
Answer: A
Rationale: The passage explains that trees "take in carbon dioxide and give off oxygen," so
cutting them reduces oxygen release and increases CO₂, which contributes to warming. Options
B and C are the opposite of the text; D is not mentioned.
Question 10
According to the passage on food and drink, as used in the last sentence, the term
"concomitant" most nearly means:
A. Unrelated
B. Accompanying
