- B. Complete loss of parathyroid hormone secretion
- C. Excess renal calcium excretion lowering serum calcium
- D. Direct calcium loss through the failing kidneys with no compensatory response
- E. Phosphate retention and secondary hyperparathyroidism

- B. A sign of acute reversible injury
- C. A pigment found mainly in neoplastic cells
- D. A "wear and tear" pigment from lipid peroxidation
- E. A product of excess melanin synthesis
Caseous granulomas in tuberculosis frequently show which secondary change over time?
- A. Metastatic calcification mainly
- B. Complete resolution without any residual change
- C. Conversion to normal lung parenchyma
- D. Dystrophic calcification of the necrotic center
- E. Progressive liquefaction with no calcification
Chronically damaged heart valves, such as in calcific aortic stenosis, undergo calcification through which mechanism?
- A. Metastatic calcification from hypercalcemia alone
- B. Calcification unrelated to any tissue damage
- C. Dystrophic calcification of chronically damaged valve tissue
