Questions & Verified Answers
1. A patient exhibits an increase in the size of the heart muscle cells due to chronic hypertension. This
cellular adaptation is known as:
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Hypertrophy
Answer: D
Rationale: Hypertrophy is an increase in the size of cells, resulting in an increase in the size of the organ. In hypertension,
the heart works harder, leading to myocardial hypertrophy.
2. Down syndrome is most commonly caused by which chromosomal abnormality?
A. Monosomy X
B. Trisomy 21
C. Trisomy 18
D. Klinefelter syndrome
Answer: B
Rationale: Down syndrome occurs when there are three copies of chromosome 21 instead of the usual two.
3. Which immunoglobulin is primarily responsible for Type I hypersensitivity reactions, such as allergic
asthma?
A. IgG
B. IgA
C. IgM
D. IgE
Answer: D
Rationale: IgE binds to mast cells and basophils, triggering the release of histamine and other mediators in allergic
responses.
4. Antidiuretic hormone (ADH) acts on the kidneys to:
A. Increase sodium excretion
B. Increase water reabsorption
C. Decrease water reabsorption
D. Promote potassium retention
Answer: B
Rationale: ADH increases the permeability of the distal tubule and collecting duct to water, promoting water reabsorption
into the blood.
5. A patient presents with peripheral edema, jugular venous distention, and hepatomegaly. These are
classic signs of:
A. Left-sided heart failure
B. Pulmonary embolism
C. Mitral valve prolapse
D. Right-sided heart failure
Answer: D
Rationale: Right-sided heart failure leads to a backup of blood into the systemic venous circulation, causing peripheral
edema and organ congestion.
