BIOD 331 / NURS 231 Module 1 Exam – Pathophysiology (Portage
Learning) – 200 Practice Questions with Verified Answers

QUESTIONS 1–200
Topic 1: Foundations of Pathophysiology


1. Which of the following best defines pathophysiology?
A) The study of the structure of body tissues and organs
B) The study of the cellular and organ changes that occur with disease and their effects on total body
function
C) The study of the normal function of the body and its systems
D) The study of the causes and origins of disease
Answer B: The study of the cellular and organ changes that occur with disease and their effects on
total body function
Rationale: Pathophysiology is the study of disordered physiological processes associated with disease or
injury.




2. Which of the following best defines pathology?
A) The study of structural changes in the body caused by disease
B) The study of functional changes in the body caused by disease
C) The study of normal body function
D) The study of disease prevention
Answer A: The study of structural changes in the body caused by disease
Rationale: Pathology focuses on structural changes; pathophysiology focuses on functional changes.




3. Which of the following best defines physiology?
A) The study of structural changes caused by disease
B) The study of cellular and organ changes with disease
C) The study of the normal function of the body and its systems
D) The study of disease origins

,Answer C: The study of the normal function of the body and its systems
Rationale: Physiology is the study of normal body function; pathophysiology is the study of altered function.
