UNIT 1: THE CELL
CHAPTER 1: THE CELL IN HEALTH AND ILLNESS
CELL STRUCTURE AND FUNCTION
20 ORIGINAL PRACTICE QUESTIONS
Question 1
A nursing student is reviewing the basic organization of human cells. Which statement best
explains why cells can perform specialized functions?
A. All cells contain identical structures that perform identical activities.
B. Cellular structure is related to the specific function the cell performs.
C. Specialized cells lose the ability to maintain internal homeostasis.
D. Cell specialization occurs only when cells become injured.
Correct Answer: B
Rationale:
Cells are structurally organized to support their specific functions. Although cells share
fundamental components, differences in cellular structure and organelle development allow cells
to perform specialized activities. For example, cells with high energy demands generally require

greater capacity for energy production. The relationship between structure and function is a
fundamental principle of cell physiology and pathophysiology.
Why the Other Options Are Incorrect:
A. Cells share common basic structures, but they do not all perform identical functions or
possess identical structural characteristics.
B. Correct. Cellular specialization depends on structural features that support particular
physiologic functions.
C. Specialized cells continue to participate in maintaining homeostasis.
D. Cell specialization is a normal physiologic process and does not require cellular injury.

Question 2
A patient experiences a condition that disrupts the normal internal environment of individual cells.
Which cellular characteristic is most directly necessary for maintaining a stable internal
environment?
A. Ability to maintain boundaries between internal and external environments
B. Ability to permanently prevent interaction with surrounding tissues
C. Ability to function independently without external nutrients
D. Ability to eliminate all communication with other cells
2
,Davis Advantage for Pathophysiology 3rd Edition Practice Questions | Nursing Pathophysiology Clinical Judgment & Exam Prep
Correct Answer: A
Rationale:
Cells must maintain an internal environment that differs from the extracellular environment.
Cellular boundaries help regulate interactions between the cell and its surroundings, allowing the
cell to maintain conditions necessary for normal structure and function. Regulation of the internal
cellular environment is essential for cellular homeostasis.
Why the Other Options Are Incorrect:
A. Correct. Cellular boundaries are essential for regulating the internal environment and
maintaining homeostasis.
B. Cells must interact with their environment rather than completely isolate themselves.
C. Cells depend on nutrients and other resources obtained from their environment.
D. Communication with other cells is essential for coordinated tissue and organ function.

Question 3
A nurse explains to a group of students that the human body is organized in progressively complex
levels. Which sequence correctly represents increasing structural complexity?
A. Organ → tissue → cell → organism
B. Cell → tissue → organ → organ system
3
, Davis Advantage for Pathophysiology 3rd Edition Practice Questions | Nursing Pathophysiology Clinical Judgment & Exam Prep
C. Tissue → cell → organ system → organ
D. Organelle → organ system → tissue → cell
Correct Answer: B
Rationale:
Cells are the fundamental structural and functional units of the body. Groups of similar cells form
tissues, tissues combine to form organs, and organs work together within organ systems. This
hierarchical organization allows increasingly complex physiologic functions.
Why the Other Options Are Incorrect:
A. This sequence reverses the normal progression of structural organization.
B. Correct. Cells form tissues, tissues form organs, and organs participate in organ systems.
C. Cells precede tissues in structural organization.
D. Organelles are components within cells and do not directly progress to organ systems in this
sequence.
