Questions & Verified Answers
1. Which process describes the reduction in cell size resulting from decreased workload or malnutrition?
A. Hypertrophy
B. Atrophy
C. Metaplasia
D. Dysplasia
Answer: B
Rationale: Atrophy is the shrinkage in cell size due to loss of cell substance, often caused by decreased use or nutrient
supply.
2. A patient is diagnosed with Down Syndrome. Which chromosomal abnormality is typically
responsible?
A. Trisomy 21
B. Trisomy 18
C. Monosomy X
D. Klinefelter syndrome
Answer: A
Rationale: Down Syndrome is primarily caused by trisomy 21, where there are three copies of chromosome 21 instead of
two.
3. What is the primary mechanism of cellular injury caused by free radicals?
A. Inhibition of calcium release
B. Increased ATP production
C. Enhanced protein synthesis
D. Oxidative stress causing membrane damage
Answer: D
Rationale: Free radicals induce oxidative stress, which leads to lipid peroxidation, protein alteration, and DNA damage.
4. Which of the following describes the movement of water across a semipermeable membrane from an
area of low solute concentration to high solute concentration?
A. Diffusion
B. Active transport
C. Filtration
D. Osmosis
Answer: D
Rationale: Osmosis is the specific term for the movement of water down its concentration gradient through a membrane.
5. Which electrolyte imbalance is most commonly associated with a ‘widened QRS complex’ and ‘peaked
T waves’ on an EKG?
A. Hyperkalemia
B. Hypokalemia
C. Hyponatremia
D. Hypocalcemia
Answer: A
Rationale: Hyperkalemia alters the cardiac resting membrane potential, leading to characteristic EKG changes like peaked
T waves and wide QRS complexes.
