The PPT has 16 slides covering: Ischemia, Hypoxia, and Necrosis. Now I'll generate professor-style MCQs from all the content.
MCQs - Pathology Lec 5-6: Definitions and Terminology
Topic 1: Ischemia
Q1. Ischemia is best defined as:
- A) Insufficient oxygen in tissues due to low hemoglobin
- B) Restriction or reduction of blood flow (and thus oxygen) to a part of the body ✅
- C) Death of cells following enzyme degradation
- D) Abnormally low blood pressure throughout the body
Q2. Which of the following is NOT a listed symptom of ischemia?
- A) Angina (chest pain)
- B) Dyspnea (shortness of breath)
- C) Cyanosis (bluish skin) ✅
- D) Paresthesia (tingling/numbness) in a limb
Cyanosis is a symptom of severe hypoxia, not listed under ischemia.
Q3. Atherosclerosis, as a cause of ischemia, is defined as:
- A) Rupture of blood vessel walls leading to hemorrhage
- B) Formation of blood clots in the venous system
- C) Thickening or hardening of arteries caused by plaque buildup in the inner lining ✅
- D) Inflammatory destruction of arterial smooth muscle
Q4. A patient presents with sudden inability to speak, loss of coordination, and dizziness. Which type of ischemia is most likely?
- A) Mesenteric ischemia
- B) Myocardial ischemia
- C) Peripheral ischemia
- D) Ischemic stroke ✅
Q5. Which of the following is a type of ischemia affecting the digestive system?
- A) Myocardial ischemia
- B) Mesenteric ischemia ✅
- C) Peripheral ischemia
- D) Transient ischemic attack
Q6. A hernia that causes ischemia does so by:
- A) Producing toxic metabolites that damage blood vessels
- B) Compressing arteries, leading to very low blood pressure
- C) Blocking blood flow when an organ protrudes through the surrounding muscle wall ✅
- D) Causing vasculitis of the mesenteric vessels
Topic 2: Hypoxia
Q7. What is the key difference between hypoxia and ischemia?
- A) Hypoxia involves total tissue death; ischemia does not
- B) Ischemia is caused only by cardiac failure; hypoxia is caused only by lung disease
- C) Hypoxia = insufficient oxygen supply to tissues; Ischemia = reduced blood flow due to blocked/constricted blood vessels ✅
- D) There is no clinical difference between the two
Q8. Hypoxemia refers to:
- A) Low oxygen levels in body tissues
- B) Low oxygen levels specifically in arterial blood ✅
- C) Reduced hemoglobin production
- D) Carbon dioxide accumulation in tissues
Q9. Which of the following is a symptom of SEVERE hypoxia (not mild hypoxia)?
- A) Headache
- B) Rapid heart rate (tachycardia)
- C) Bradycardia (slow heart rate) ✅
- D) Anxiety
Q10. Lack of oxygen specifically to the brain is called:
- A) Pulmonary hypoxia
- B) Anemic hypoxia
- C) Cerebral hypoxia ✅
- D) Histotoxic hypoxia
Q11. A patient with cyanide poisoning develops tissue hypoxia despite normal oxygen levels in the blood. This is classified as:
- A) Hypoxemic hypoxia
- B) Circulatory hypoxia
- C) Anemic hypoxia
- D) Histotoxic hypoxia ✅
Histotoxic hypoxia = cells cannot utilize oxygen even when it is available.
Q12. A mountaineer climbing at high altitude develops hypoxia. Which type is this?
- A) Anemic hypoxia
- B) Histotoxic hypoxia
- C) Hypoxemic hypoxia ✅
- D) Circulatory hypoxia
High altitude reduces ambient oxygen, leading to low blood oxygen (hypoxemia), hence hypoxemic hypoxia.
Q13. A patient with congestive heart failure has adequate blood oxygen saturation but still develops tissue hypoxia. The most likely type is:
- A) Anemic hypoxia
- B) Circulatory (stagnant/ischemic) hypoxia ✅
- C) Histotoxic hypoxia
- D) Hypoxemic hypoxia
Q14. Emphysema is defined as:
- A) Fluid accumulation in the alveolar spaces
- B) Blood clot formation in the pulmonary vasculature
- C) Gradual damage of lung tissue, specifically destruction of the alveoli ✅
- D) Scarring and fibrosis of lung tissue
Q15. Which of the following lung conditions increases the risk of hypoxia by collapsing the lung?
- A) Pulmonary fibrosis
- B) Pulmonary edema
- C) Pneumothorax ✅
- D) Pulmonary hypertension
Topic 3: Necrosis
Q16. Necrosis is best defined as:
- A) Programmed cell death with intact cell membrane
- B) Cell death + the morphological changes that follow in a living tissue ✅
- C) Reversible cell injury caused by ischemia
- D) Inflammation of living cells caused by bacterial toxins
Q17. Which equation summarizes necrosis?
- A) Necrosis = Apoptosis + Inflammation
- B) Necrosis = Ischemia + Hypoxia
- C) Necrosis = Cell death + Morphological changes ✅
- D) Necrosis = Protein synthesis + Cell division
Q18. The two basic mechanisms responsible for morphological changes in necrosis are:
- A) Apoptosis and autophagy
- B) Enzymatic degradation of the cell and denaturation of proteins ✅
- C) Lipid peroxidation and DNA fragmentation
- D) Mitochondrial swelling and lysosomal rupture
Q19. Heterolysis refers to:
- A) Self-digestion of a cell by its own lysosomes
- B) Enzymatic degradation of dead cells by hydrolytic enzymes from inflammatory cells (WBCs) ✅
- C) Protein denaturation caused by heat
- D) Fragmentation of the nucleus in apoptotic cells
Q20. Heterolysis leads to which pattern of necrosis?
- A) Coagulative necrosis
- B) Caseous necrosis
- C) Liquefactive necrosis ✅
- D) Fat necrosis
Hydrolytic enzymes from invading WBCs break down dead tissue completely, resulting in liquefaction.
Q21. Hydrolytic enzymes responsible for heterolysis are derived from the lysosomes of which cells?
- A) Dead epithelial cells
- B) Invading inflammatory cells (WBCs) ✅
- C) Smooth muscle cells of the blood vessel wall
- D) Hepatocytes
Mixed/Clinical Integration
Q22. A patient with severe anemia develops headache, rapid breathing, and confusion. The type of hypoxia present is:
- A) Histotoxic hypoxia
- B) Circulatory hypoxia
- C) Hypoxemic hypoxia
- D) Anemic hypoxia ✅
Q23. Which of the following best distinguishes ischemia from anemic hypoxia?
- A) Both involve blocked blood vessels
- B) Ischemia results from vascular compromise; anemic hypoxia results from insufficient red blood cells to carry oxygen ✅
- C) Anemic hypoxia involves normal RBC count
- D) Ischemia involves low hemoglobin only
Q24. Morphological changes in necrosis are caused by the progressive degradative action of:
- A) Ribosomal RNA on dead cell organelles
- B) Complement proteins on the cell membrane
- C) Enzymes on dead cells ✅
- D) Prostaglandins on the vascular endothelium
Q25. Which of the following is CORRECTLY matched?
- A) Ischemic stroke - arm or leg
- B) Peripheral ischemia - brain
- C) Myocardial ischemia - heart muscle ✅
- D) Mesenteric ischemia - brain
