Test Bank for Comprehensive Radiographic Pathology 5th Edition By Eisenberg Complete All Chapters . Heat and redness associated with inflammation is produced by: a. Hyperemia b. Scar tissue c. Hyperplasia d. Infarction ANS: A This hyperemia produces the heat and redness associated with inflammation. REF: p. 3 7. In an injury, the destroyed tissue is replaced with: a. Granulomatous inflammation b. Granulation tissue c. Phagocytes d. Pyogens ANS: B A fibrous scar replaces the area of destroyed tissue with granulation tissue. Granulation tissue refers to a combination of young, developing capillaries and actively proliferating fibroblasts, which produce connective tissue fibers (collagen) that replace the dead tissue. REF: p. 4 8. Of the five clinical signs of acute inflammation, the medical term for swelling is: a. Edema b. Tumor c. Calor 4 d. Dolor ANS: B The five clinical signs of acute inflammation are rubor (redness), calor (heat), tumor (swelling), dolor (pain), and loss of function. REF: p. 4 9. Some bacterial organisms that produce these substances that cause damage to the tissue and incite the inflammatory process are known as: a. Toxoids b. Pyogens c. Toxins d. Abscesses ANS: C Some bacterial organisms (such as staphylococci and streptococci) produce toxins that damage the tissues and incite an inflammatory response. REF: p. 4 10. Chronic inflammation in a localized area, which often has a centralized necrosis is called: a. An exudates b. A granuloma c. An abscess d. Hyperplasia ANS: B A granuloma is a localized area of chronic inflammation, often with central necrosis. REF: p. 4 5 All information provided for reference only 11. In acute inflammation, the localized heat and redness are a result of the: a. Migration of circulating white blood cells b. Increased blood flow and vascular permeability c. Regeneration of normal parenchymal cells d. Enzymatic digestion of dead cells ANS: B The localized heat and redness result from increased blood flow in the microcirculation at the site of injury. REF: p. 4 12. In pyogenic infections, the body responds by producing a thick, yellow fluid called: a. Bacteria b. Pus c. Edema d. A scar ANS: B The presence of pyogenic bacteria leads to the production of a thick, yellow fluid called pus, which contains dead white blood cells, inflammatory exudates, and bacteria. REF: p. 4 13. All pyogens have the ability to enter the blood circulation causing: a. Bacteremia b. Phagocytosis c. Septicemia d. Keloid tissue 6 All information provided for reference only ANS: A All pyogens, wherever they become implanted, have the ability to invade blood vessels to produce bacteremia, with the potential involvement of other organs and tissues in the body. REF: p. 4 14. Connective tissue fibers replacing dead tissue, then contracting in the abdomen are known as: a. Keloids b. Suppurative inflammation c. Fibrous adhesions d. Hyperemia ANS: C Eventually the strong connective tissue contracts to produce a fibrous scar. In the abdomen, such fibrous adhesions can narrow loops of intestine and result in an obstruction. REF: p. 4 15. An accumulation of abnormal amounts of fluid in the intercellular tissue throughout the body is called: a. Bacteremia b. Elephantiasis c. Filariasis d. Anasarca ANS: D Generalized edema occurs with pronounced swelling of subcutaneous tissues throughout the body (anasarca). REF: p. 4 16. Localized _____ is produced in an inflammatory reaction as a result of a fluid accumulation. 7 All information provided for reference only a. Filariasis b. Edema c. Elephantiasis d. Fibrous adhesions ANS: B Edema is the accumulation of abnormal amounts of fluid in the intercellular tissue spaces or body cavities. Localized edema results from an inflammatory reaction. REF: p. 4 17. An inflammation associated with pus formation is: a. Bacteremia b. Phagocytosis c. Suppurative d. Hyperemia ANS: C Suppurative inflammation is associated with pus formation. REF: p. 4 18. The protein-rich fluid associated with swelling in an inflammatory process is: a. Exudate b. Transudate c. Pus d. Permeable ANS: A 8 All information provided for reference only This inflammatory exudate in the tissues results in the swelling associated with inflammation. The protein-rich exudate of inflammation must be differentiated from a transudate, a low-protein fluid, such as that seen in the pulmonary edema that develops in congestive heart failure. REF: p. 3 19. The low-protein fluid associated with the inflammatory process as seen in pulmonary edema is called: a. An abscess b. Exudate c. Transudate d. Filariasis ANS: C The protein-rich exudate of inflammation must be differentiated from a transudate, a low-protein fluid, such as that seen in the pulmonary edema that develops in congestive heart failure. REF: p. 3 20. A localized area of ischemic necrosis within a tissue or organ produced by vascular occlusion is a(n): a. Gangrene b. Infarct c. Purpura d. Ecchymosis ANS: B An infarct is a localized area of ischemic necrosis within a tissue or organ produced by occlusion of either its arterial supply or its venous drainage. REF: p. 5 21. Depriving tissues of oxygen and nutrients caused by an arterial vessel narrowing is referred to as: 9 All information provided for reference only a. Ischemia b. Petechiae c. Filariasis d. Gangrene ANS: A Ischemia refers to an interference with the blood supply to an organ or part of an organ, depriving the organ’s cells and tissues of oxygen and nutrients. REF: p. 5 22. The progression of a loss of oxygen and nutrients resulting in tissue necrosis especially in the diabetic’s foot is called: a. Infarction b. Gangrene c. Ischemia d. Hemorrhage ANS: B Severe arterial disease of the lower extremities may result in necrosis of several toes or a large segment of the foot, a condition called gangrene. A frequent symptom in diabetic patients is ischemia of the foot, which may progress to infarction and result in gangrene. REF: p. 5 23. A subcutaneous hematoma greater than 1 to 2 cm is called a(n): a. Purpura b. Ecchymosis c. Petechia d. Infarct ANS: B EMAIL ME: For help with report, Assignment, Essay and thesis writing 10 All information provided for reference only A large (greater than 1 to 2 cm) subcutaneous hematoma, or bruise, is called an ecchymosis. REF: p. 6 24. An accumulation of blood trapped within the body tissues is known as a(an): a. Hematoma b. Ecchymosis c. Petechiae d. Pleural effusion ANS: A Blood may be trapped within body tissues resulting in an accumulation called a hematoma. REF: p. 5 25. Bleeding into mucous membranes or serosal surfaces is referred to as: a. Petechiae b. Hemorrhage c. Purpura d. Ecchymosis ANS: A Minimal hemorrhages into the skin, mucous membranes, or serosal surfaces are called petechiae. REF: p. 5 26.
