Rubin’s Pathology: Clinicopathologic Foundations of Medicine, 7th Edition TEST BANK Chapter 1: Cell Adaptation, Injury and Death 1. Ischemia and other toxic injuries increase the accumulation of intracellular calcium as a result of: A) release of stored calcium from the mitochondria. B) improved intracellular volume regulation. C) decreased influx across the cell membrane. D) attraction of calcium to fatty infiltrates. 2. The patient is found to have liver disease, resulting in the removal of a lobe of his liver. Adaptation to the reduced size of the liver leads to _ of the remaining liver cells. A) metaplasia B) organ atrophy C) compensatory hyperplasia D) physiologic hypertrophy 3.

Despite the low levels of radiation used in contemporary radiologic imaging, a radiology technician is aware of the need to minimize her exposure to ionizing radiation. What is the primary rationale for the technicians precautions? A) Radiation stimulates pathologic cell hypertrophy and hyperplasia. B) Radiation results in the accumulation of endogenous waste products in the cytoplasm. C) Radiation interferes with DNA synthesis and mitosis. D) Radiation decreases the action potential of rapidly dividing cells. 15. The parents of a 4 -year -old girl have sought care because their daughter has admitted to chewing and swallowing imported toy figurines that have been determined to be made of lead. Which of the following blood tests should the care team prioritize? A) White blood cell levels with differential B) Red blood cell levels and morphology C) Urea and creatinine levels D) Liver function panel A 70 -year -old male patient has been admitted to a hospital for the treatment of a recent hemorrhagic stroke that has left him with numerous motor and sensory 16. deficits. These deficits are most likely the result of which of the following mechanisms of cell injury? A) Free radical injury B) Hypoxia and ATP depletion C) Interference with DNA synthesis D) Impaired calcium homeostasis 17. Which of the following processes associated with cellular injury is most likely to be reversible? A) Cell damage resulting from accumulation of fat in the cytoplasm B) Cellular changes as a result of ionizing radiation C) Cell damage from accumulation of free radicals D) Apoptosis 18. The extrinsic pathway of apoptosis can be initiated by: A) damage to cellular DNA. B) decreased ATP levels. C) activation of the p53 protein. D) activation of death receptors on the cell surface. 19. A patient with severe peripheral vascular disease has developed signs of dry gangrene on the great toe of one foot. Which of the following pathophysiologic processes most likely contributed to this diagnosis? A) Inappropriate activation of apoptosis B) Bacterial invasion C) Impaired arterial blood supply D) Metaplastic cellular changes 20. Which of the following facts underlies the concept of replicative senescence? A) Genes controlling longevity are present or absent in varying quantities among different individuals. B) Telomeres become progressively shorter in successive generations of a cell. C) The damaging influence of free radicals increases exponentially in later generations of a cell. D) Ans w er Aging produces mutations in DNA and deficits in DNA repair. Key 1. A 2. C 3. B 4. C 5. A 6. B 7. C 8. B 9. B 10. A 11. C 12. A 13. D 14. C 15. B 16. B 17. A 18. D 19. C 20 .
