Questions & Verified Answers
1. A 45-year-old male with long-standing hypertension presents with an enlarged heart. This
increase in myocardial cell size is best described as:
A. Hyperplasia
B. Atrophy
C. Hypertrophy
D. Metaplasia
Answer: C
Rationale: Hypertrophy is an increase in the size of cells in response to mechanical stimuli (such as high blood
pressure), leading to an increase in the size of the organ. Recognizing this principle allows the nurse to
prioritize care, anticipate complications, and provide accurate patient education.
2. Which type of cellular adaptation involves the replacement of one mature cell type by another
less mature cell type?
A. Dysplasia
B. Anaplasia
C. Hyperplasia
D. Metaplasia
Answer: D
Rationale: Metaplasia is the reversible replacement of one mature cell 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.
3. A patient is diagnosed with pernicious anemia. What is the underlying pathophysiological
cause?
A. Iron deficiency in the diet
B. Bone marrow failure
C. Excessive destruction of red blood cells
D. Lack of intrinsic factor for Vitamin B12 absorption
Answer: D
Rationale: Pernicious anemia is caused by a lack of intrinsic factor, which is required for the gastric absorption
of vitamin B12. 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. Which hypersensitivity reaction is mediated by IgE and involves mast cell degranulation?
A. Type II
B. Type I
C. Type III
D. Type IV
Answer: B
Rationale: Type I hypersensitivity is an immediate allergic reaction mediated by IgE antibodies binding to mast
cells. This is an important clinical concept because selecting the correct answer (B) requires understanding
both the pathophysiology and the practical nursing implications. Recognizing this principle allows the nurse to
prioritize care, anticipate complications, and provide accurate patient education.
5. What is the primary mechanism of cellular injury caused by hypoxia?
A. Increased protein synthesis
B. Mitochondrial swelling
C. Intracellular alkalosis
D. Decreased ATP production
Answer: D
Rationale: Hypoxia leads to reduced aerobic respiration in mitochondria, causing a decrease in ATP
production which disrupts the sodium-potassium pump. 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.
6. In the TNM staging system for cancer, what does the ‘N’ represent?
A. Necrosis of the tumor
B. Number of tumors
C. Nuclear grade
D. Involvement of regional lymph nodes
Answer: D
Rationale: TNM stands for Tumor (size/extent), Nodes (lymph node involvement), and Metastasis (distant
spread). This is an important clinical concept because selecting the correct answer (D) requires understanding
both the pathophysiology and the practical nursing implications. Recognizing this principle allows the nurse to
prioritize care, anticipate complications, and provide accurate patient education.
