GRADED A+
1. Pathophysiology is best defined as the study of:
A. Normal body structures only
B. Medications used to treat diseases
C. Changes in body function caused by disease processes
D. Surgical procedures used to correct disorders
Answer: C
Rationale: Pathophysiology focuses on how diseases alter normal physiological processes and
how these changes produce signs and symptoms.
2. The nurse understands that the primary goal of homeostasis is to:
A. Prevent all diseases
B. Maintain constant body temperature only
C. Maintain a stable internal environment despite external changes
D. Eliminate all cellular changes
Answer: C
Rationale: Homeostasis refers to the body’s ability to maintain balance in internal conditions
such as temperature, pH, glucose, and fluid levels.
3. Which component is considered part of the inflammatory response?
,A. Decreased blood flow to injured tissue
B. Reduced immune activity
C. Release of chemical mediators that promote healing and defense
D. Prevention of all cellular damage
Answer: C
Rationale: Inflammation involves immune activation, increased blood flow, and release of
mediators that help remove harmful stimuli and begin repair.
4. A patient has an elevated white blood cell count. The nurse recognizes this finding may
indicate:
A. Decreased immune response
B. Low oxygen levels
C. Activation of the immune system due to infection or inflammation
D. Reduced bone marrow function
Answer: C
Rationale: Increased white blood cells commonly occur as the body responds to infection,
inflammation, or other immune challenges.
5. Which statement BEST describes apoptosis?
A. Uncontrolled cell growth
B. Accidental cell injury only
C. Programmed cell death that removes damaged or unnecessary cells
D. Rapid inflammation of tissues
Answer: C
Rationale: Apoptosis is a controlled process of cellular self-destruction that helps maintain
normal tissue function.
6. Necrosis differs from apoptosis because necrosis:
A. Is always beneficial to the body
B. Occurs only during normal development
C. Results from uncontrolled cell injury and often causes inflammation
D. Does not involve cell damage
Answer: C
, Rationale: Necrosis occurs when cells are damaged by injury, toxins, infection, or lack of
oxygen, often triggering inflammation.
7. A patient develops swelling after an injury. Which process explains this finding?
A. Decreased capillary permeability
B. Reduced immune response
C. Movement of fluid from blood vessels into surrounding tissues
D. Loss of all inflammatory activity
Answer: C
Rationale: Inflammation increases vascular permeability, allowing fluid and immune cells to
move into tissues, causing swelling.
8. Which factor is MOST likely to contribute to cellular injury?
A. Adequate oxygen supply
B. Normal nutrient availability
C. Hypoxia and reduced oxygen delivery to tissues
D. Effective waste removal
Answer: C
Rationale: Oxygen deprivation interferes with cellular energy production and can lead to
injury or cell death.
9. The nurse understands that ischemia refers to:
A. Excess oxygen delivery
B. Increased blood glucose levels
C. Reduced blood supply to tissues
D. Increased immune activity
Answer: C
Rationale: Ischemia occurs when blood flow is insufficient, reducing oxygen and nutrient
delivery to tissues.
10. Which laboratory value is commonly associated with inflammation?
A. Decreased inflammatory markers
B. Elevated C-reactive protein (CRP)
C. Reduced white blood cells in every condition
D. Increased oxygen saturation
