CHAPTER 1: INTRODUCTION TO PATHOPHYSIOLOGY
This chapter introduces fundamental concepts of pathophysiology,
including normal physiological processes, mechanisms of disease,
homeostasis, cellular adaptation, and the body’s responses to injury
and illness. Emphasis is placed on clinical reasoning, risk factors,
genetics, environmental influences, and the nurse’s role in assessing
pathologic changes, promoting safety, recognizing early
manifestations of disease, and applying evidence-based interventions
in patient care.
1. Which term best describes the study of functional changes
associated with disease processes?
, A. Anatomy
B. Physiology
C. Pathophysiology
D. Histology
Correct Answer: C
Rationale: Pathophysiology examines functional alterations caused by
disease or injury. Anatomy studies structure, physiology studies
normal function, and histology studies tissues.
2. A nurse explains that homeostasis refers to:
A. Permanent organ damage
B. Stable internal balance
C. Rapid cellular death
D. External environmental changes
Correct Answer: B
Rationale: Homeostasis is the body’s ability to maintain a stable
internal environment despite external or internal changes. Disease
may disrupt this balance.
