Q5: Main Idea - Passage 5
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
passage: "The pancreas is a glandular organ located behind the stomach. It has two main functions:
exocrine and endocrine. The exocrine function produces digestive enzymes that help break down

and endocrine (hormones). Option B best captures this. [100% CORRECT]
Q6: Main Idea - Passage 6
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
,3
passage: "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 through
sweating and blood flow. Additionally, the skin contains nerve endings that allow for the sensation
of touch, pressure, pain, and temperature. The skin is composed of three layers: the epidermis,
dermis, and hypodermis." What is the main idea of this passage?
A. The skin is the largest organ of the body
B. The skin serves as a protective barrier

and sensation. Option C best captures the main idea. [100% CORRECT]
Q7: Main Idea - Passage 7
The nursing student is reviewing reading comprehension for the HESI A2. Read the following
passage: "The digestive system is responsible for breaking down food into nutrients that the body
can absorb. The process begins in the mouth, where food is chewed and mixed with saliva. The food
then travels through the esophagus to the stomach, where it is mixed with gastric juices. The small
intestine absorbs most of the nutrients, and the large intestine absorbs water and eliminates waste."
