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. Atrophy is
shrinkage, hypertrophy is increase in cell size, and metaplasia is the replacement of one cell type with another.
2. A patient has suffered a myocardial infarction. Which process describes the programmed cell death
that occurs to damaged cells without causing an inflammatory response?
A. Necrosis
B. Infarction
C. Autophagy
D. Apoptosis
Answer: D
Rationale: Apoptosis is programmed cell death, a distinct process from necrosis, which is accidental cell death that typically
triggers inflammation.
3. Which type of hypersensitivity reaction is mediated by IgE and involves the release of histamine from
mast cells?
A. Type I
B. Type II
C. Type III
D. Type IV
Answer: A
Rationale: Type I hypersensitivity is IgE-mediated and includes allergic reactions like asthma and anaphylaxis.
4. A patient presents with pulmonary edema due to left-sided heart failure. What is the primary
physiological cause of this fluid shift into the alveoli?
A. Increased capillary hydrostatic pressure
B. Decreased capillary hydrostatic pressure
C. Increased capillary oncotic pressure
D. Increased interstitial oncotic pressure
Answer: A
Rationale: Left-sided heart failure leads to backup of blood into the pulmonary circulation, increasing pulmonary capillary
hydrostatic pressure, which forces fluid into the interstitial and alveolar spaces.
