Pathology MCQs
Pathology MCQs are designed to test a student's understanding of disease mechanisms, histopathology, and clinical correlations. Questions range from general pathology to systemic diseases affecting organs like the liver, lungs, heart, and kidneys. Ideal for MDCAT, NTS, USMLE, and FCPS aspirants, these quizzes help reinforce critical concepts and bridge the gap between theory and clinical application.
Q: Exudate differs from transudate by
A) High protein content and cellular debris
B) Clear appearance
C) Caused by decreased oncotic pressure
D) Low specific gravity
✅ Correct Answer: A
Explanation: Exudates form due to increased vascular permeability and contain proteins and cells.
Q: Oncogenes promote cancer by
A) Enhancing apoptosis
B) Repairing DNA
C) Inhibiting tumor suppressors
D) Promoting cell proliferation
✅ Correct Answer: D
Explanation: Oncogenes accelerate cell division and contribute to tumor formation.
Q: A nuclear change seen in necrosis involving nuclear fading
A) Pyknosis
B) Karyolysis
C) Karyorrhexis
D) Hyperchromasia
✅ Correct Answer: B
Explanation: Karyolysis results from enzymatic degradation of DNA during necrosis.
Q: The typical vascular change in chronic inflammation
A) Increased permeability
B) Thrombosis
C) Angiogenesis
D) Vasodilation
✅ Correct Answer: C
Explanation: Angiogenesis provides blood supply to sustain chronic inflammatory tissue.
Q: Hemorrhagic infarcts commonly occur in
A) Brain
B) Kidneys
C) Lungs
D) Liver
✅ Correct Answer: C
Explanation: Lungs have dual circulation, making hemorrhagic infarcts more likely when blood re-enters necrotic areas.
Q: The main structural protein deposited during fibrosis
A) Collagen
B) Myosin
C) Fibrin
D) Elastin
✅ Correct Answer: A
Explanation: Collagen is produced by fibroblasts and accumulates in chronic inflammation and healing.
Q: Hematopoiesis primarily takes place in
A) Kidney
B) Liver
C) Spleen
D) Bone marrow
✅ Correct Answer: D
Explanation: Bone marrow is the primary site of blood cell production in adults.
Q: Malignant tumors typically exhibit
A) Uniform structure
B) Slow regression
C) Rapid growth
D) Low mitotic rate
✅ Correct Answer: C
Explanation: Malignant tumors grow quickly due to high mitotic activity.
Q: Granuloma formation is characteristic of
A) Tuberculosis
B) Diabetes
C) Hypertension
D) Anemia
✅ Correct Answer: A
Explanation: Tuberculosis often triggers a chronic inflammatory response forming granulomas.
Q: Necrosis refers to
A) New cell formation
B) Cell regeneration
C) Controlled cell death
D) Uncontrolled cell death
✅ Correct Answer: D
Explanation: Necrosis is an accidental and pathological form of cell death.
