Questions & Verified Answers
1. Which cellular adaptation is characterized by an increase in the number of cells in an organ
or tissue?
A. Atrophy
B. Hyperplasia
C. Hypertrophy
D. Metaplasia
Answer: B
Rationale: Hyperplasia is an increase in the number of cells resulting from an increased rate of cellular
division. Hypertrophy is an increase in cell size. Exam questions often test the ability to distinguish this concept
from closely related distractors, making a clear rationale essential for mastery. Applying this knowledge in
clinical settings supports safe, evidence-based practice and improves patient outcomes.
2. Which process results in the programmed death of a cell to maintain homeostasis?
A. Apoptosis
B. Necrosis
C. Autophagy
D. Liquefaction
Answer: A
Rationale: Apoptosis is a distinct type of cell death that is programmed and involves the dropping off of cellular
fragments. Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide
accurate patient education. Exam questions often test the ability to distinguish this concept from closely related
distractors, making a clear rationale essential for mastery.
3. What is the primary cause of cellular injury during hypoxia?
A. Accumulation of lactic acid
B. Sodium-potassium pump overactivity
C. Increase in cellular pH
D. Decrease in ATP production
Answer: D
Rationale: Hypoxia leads to reduced ATP production, which causes the failure of the sodium-potassium pump
and leads to cellular swelling. Recognizing this principle allows the nurse to prioritize care, anticipate
complications, and provide accurate patient education. Exam questions often test the ability to distinguish this
concept from closely related distractors, making a clear rationale essential for mastery.

4. A patient with chronic gastroesophageal reflux disease (GERD) shows a change in
esophageal epithelial cells from squamous to columnar. This is known as:
A. Anaplasia
B. Dysplasia
C. Hyperplasia
D. shows a change in esophageal epithelial cells from squamous to columnar. This is known as:
Answer: D
Rationale: Metaplasia is the reversible replacement of one mature cell type by another, often as a result of
chronic irritation or inflammation. Recognizing this principle allows the nurse to prioritize care, anticipate
complications, and provide accurate patient education. Exam questions often test the ability to distinguish this
concept from closely related distractors, making a clear rationale essential for mastery.
5. What is the hallmark sign of Vitamin B12 deficiency anemia (Pernicious Anemia)?
A. Microcytic, hypochromic cells
B. Macrocytic, normochromic cells
C. Normocytic, normochromic cells
D. Spherocytic cells
Answer: B
Rationale: Pernicious anemia is a megaloblastic anemia characterized by large (macrocytic) red blood cells
due to impaired DNA synthesis. Exam questions often test the ability to distinguish this concept from closely
related distractors, making a clear rationale essential for mastery. Applying this knowledge in clinical settings
supports safe, evidence-based practice and improves patient outcomes.
6. Which electrolyte imbalance is most commonly associated with a prolonged QT interval on
an EKG?
A. Hypercalcemia
B. Hypocalcemia
C. Hyperkalemia
D. Hypokalemia
Answer: B
Rationale: Hypocalcemia increases neuromuscular excitability and is a classic cause of a prolonged QT
interval. Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide
accurate patient education. Exam questions often test the ability to distinguish this concept from closely related
distractors, making a clear rationale essential for mastery.
