SECTION 1: MAIN IDEA - Questions 1-12
Q1: Main Idea - Passage 1
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
passage: "The skeletal system provides support and protection for the body. It also allows for
movement, stores minerals, and produces blood cells. The adult human skeleton consists of 206

Correct Answer: C
Rationale: The passage describes multiple functions of the skeletal system: support, protection,
movement, mineral storage, and blood cell production. Option C best captures this. [100% CORRECT]
Q2: Main Idea - Passage 2
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
passage: "The muscular system is responsible for movement. There are three types of muscle tissue:
skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscle is attached to bones and is
voluntary. Cardiac muscle is found in the heart and is involuntary. Smooth muscle is found in the
walls of organs and is involuntary." What is the main idea of this passage?
A. The muscular system is responsible for movement
B. There are three types of muscle tissue
C. Skeletal muscle is voluntary
D. Cardiac muscle is involuntary
Correct Answer: A
Rationale: The passage introduces the muscular system's function (movement) and then describes
the three types of muscle tissue. Option A best captures the main idea. [100% CORRECT]
Q3: Main Idea - Passage 3
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
passage: "The cardiovascular system consists of the heart, blood vessels, and blood. The heart
pumps blood through the blood vessels to deliver oxygen and nutrients to tissues and remove waste
,2
products. The cardiovascular system also helps regulate body temperature and pH. The average
adult has about 5 liters of blood." What is the main idea of this passage?
A. The cardiovascular system consists of the heart, blood vessels, and blood
B. The heart pumps blood through the blood vessels
C. The cardiovascular system delivers oxygen and nutrients
D. The cardiovascular system has multiple functions
Correct Answer: D
Rationale: The passage describes multiple functions of the cardiovascular system: delivering oxygen
and nutrients, removing waste, regulating temperature and pH. Option D best captures this. [100%
CORRECT]
Q4: Main Idea - Passage 4
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
passage: "The urinary system consists of the kidneys, ureters, bladder, and urethra. The kidneys
filter waste products from the blood to form urine. The ureters transport urine from the kidneys to
the bladder. The bladder stores urine until it is eliminated through the urethra. The urinary system
also helps regulate fluid and electrolyte balance." What is the main idea of this passage?
A. The urinary system consists of the kidneys, ureters, bladder, and urethra
B. The kidneys filter waste products from the blood
C. The urinary system filters waste and regulates fluid balance
D. The bladder stores urine
Correct Answer: C
Rationale: The passage describes the components of the urinary system and its functions: filtering
waste and regulating fluid balance. Option C best captures this. [100% CORRECT]
Q5: Main Idea - Passage 5
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
passage: "The reproductive system is responsible for producing offspring. In males, the reproductive
system produces sperm and hormones. In females, the reproductive system produces eggs and
hormones. The male and female reproductive systems work together to facilitate fertilization and
reproduction. The reproductive system also influences secondary sexual characteristics." What is the
main idea of this passage?
A. The reproductive system produces offspring
B. The male reproductive system produces sperm
C. The female reproductive system produces eggs
D. The reproductive system influences secondary sexual characteristics
Correct Answer: A
Rationale: The passage introduces the reproductive system's primary function: producing offspring.
Option A best captures the main idea. [100% CORRECT]
Q6: Main Idea - Passage 6
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
passage: "The lymphatic system is a network of tissues, vessels, and organs that work together to

maintain fluid balance, defend the body against infection, and absorb fats from the digestive system.
Lymph nodes filter lymph fluid and contain immune cells that help fight infection. The lymphatic
system is closely associated with the immune system." What is the main idea of this passage?
A. The lymphatic system maintains fluid balance
B. The lymphatic system defends the body against infection
C. The lymphatic system has multiple functions
D. Lymph nodes filter lymph fluid
Correct Answer: C
Rationale: The passage describes multiple functions of the lymphatic system: fluid balance, immune
defense, and fat absorption. Option C best captures this. [100% CORRECT]
Q7: Main Idea - Passage 7
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
passage: "The integumentary system consists of the skin, hair, nails, and exocrine glands. The skin is
the largest organ of the body. It serves as a protective barrier against pathogens, UV radiation, and
physical injury. The skin also helps regulate body temperature and contains nerve endings for
sensation." What is the main idea of this passage?
A. The integumentary system consists of the skin, hair, nails, and exocrine glands
B. The skin is the largest organ of the body
C. The integumentary system serves multiple protective functions
D. The skin contains nerve endings for sensation
Correct Answer: C
Rationale: The passage describes the integumentary system's components and its protective
functions. Option C best captures the main idea. [100% CORRECT]
Q8: Main Idea - Passage 8
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
passage: "The respiratory system is responsible for the exchange of oxygen and carbon dioxide
between the air and the blood. The lungs are the primary organs of the respiratory system. Air
enters the body through the nose or mouth, travels down the trachea, and into the lungs. Oxygen is
absorbed into the blood, and carbon dioxide is expelled from the body." What is the main idea of
this passage?
A. The respiratory system is responsible for gas exchange
B. The lungs are the primary organs of the respiratory system
C. Air enters through the nose or mouth
D. Oxygen is absorbed into the blood
Correct Answer: A
Rationale: The passage describes the respiratory system's primary function: gas exchange. Option A
