Questions & Verified Answers
1. Which cellular adaptation is characterized by the replacement of one mature cell type by
another, often as a response to chronic irritation?
A. Metaplasia
B. Hyperplasia
C. Dysplasia
D. Atrophy
Answer: A
Rationale: Metaplasia is the reversible replacement of one mature cell type by another less
differentiated cell type, typically to better withstand environmental stress. In practice, this guides the
nurse to set priorities and protect the client from harm. Safety, nutrition, and clear communication are
frequent priorities. Clear understanding of this concept improves both test performance and everyday
clinical judgment. Practice applying it to short case scenarios to lock the idea in place.
2. A patient with chronic hypertension exhibits thickening of the left ventricular wall. This is
an example of which cellular process?
A. Physiologic hypertrophy
B. Pathologic hypertrophy
C. Compensatory hyperplasia
D. Hormonal hyperplasia
Answer: B
Rationale: Pathologic hypertrophy occurs in response to an increased workload, such as the heart
pumping against high systemic pressure in hypertension. This knowledge supports safe care and
helps the nurse teach the client and family clearly and simply. Clear teaching improves cooperation
and reduces anxiety. Exam questions often test whether you can pick the most practical and safe
choice for the client in real situations. Focus on what the nurse can actually do right now.

3. What is the most common cause of cellular injury?
A. Free radicals
B. Chemical agents
C. Hypoxia
D. Genetic factors
Answer: C
Rationale: Hypoxia, or lack of sufficient oxygen, is the single most common cause of cellular injury,
often resulting from ischemia. Clear understanding of this concept improves both test performance and
everyday clinical judgment. Practice applying it to short case scenarios to lock the idea in place.
Understanding this helps the nurse notice early warning signs and act before the problem gets worse.
Early action often prevents bigger complications for the client.
4. Which type of necrosis is most commonly associated with ischemic injury to the brain?
A. Coagulative necrosis
B. Caseous necrosis
C. Fat necrosis
D. Liquefactive necrosis
Answer: D
Rationale: Liquefactive necrosis occurs in the brain because brain cells are rich in digestive hydrolytic
enzymes and lipids. Remembering this point will help you decide the best nursing action when similar
questions appear on the exam. Link the answer to the client’s current condition and risk level. Knowing
the reason behind the correct answer makes it easier to rule out the wrong options quickly. Look for
the choice that protects the client and matches the priority need.
