Questions & Verified Answers
1. Which cellular adaptation process is characterized by an increase in the number of cells in
an organ or tissue resulting from an increased rate of cellular division?
A. Hypertrophy
B. Metaplasia
C. Hyperplasia
D. Dysplasia
Answer: C
Rationale: Hyperplasia is an increase in the number of cells, whereas hypertrophy is an increase in
the size of existing cells. 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. Clear

2. In the context of cellular injury, which mechanism is primarily responsible for the swelling
of the cell (oncosis) during hypoxic injury?
A. Increased intracellular calcium levels
B. Failure of the sodium-potassium pump
C. Lactic acid accumulation
D. Ribosome detachment
Answer: B
Rationale: Hypoxia leads to ATP depletion, causing the Na+/K+ pump to fail, which leads to sodium
and water accumulation inside the cell, causing swelling. This knowledge supports safe care and helps
the nurse teach the client and family clearly and simply. Clear teaching improves cooperation and
reduces anxiety. This is important because the nurse must choose the action that keeps the client
safest while still meeting their basic needs. Always think about safety first when answering these
questions.

3. What is the primary difference between apoptosis and necrosis?
A. Apoptosis involves inflammation; necrosis does not
B. Apoptosis is always pathological; necrosis is always physiological
C. Apoptosis is programmed cell death without inflammation; necrosis involves cell lysis and
inflammation
D. Necrosis involves cell shrinkage; apoptosis involves cell swelling
Answer: C
Rationale: Apoptosis is a controlled, programmed process that avoids inflammation, whereas necrosis
is messy, involving cell rupture and inflammatory response. 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.
4. Which electrolyte imbalance is most commonly associated with the development of
Trousseau and Chvostek signs?
A. Hyperkalemia
B. Hypocalcemia
C. Hypercalcemia
D. Hypomagnesemia
Answer: B
Rationale: Hypocalcemia increases neuromuscular excitability, leading to tetany, which is clinically
assessed via Trousseau and Chvostek signs. 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. This knowledge supports safe care and helps the nurse teach the client and family
clearly and simply. Clear teaching improves cooperation and reduces anxiety.
