ANS: B Proteins play a role in blood clotting and the regulation of fluid volume. Platelets and red blood cells are formed elements and, therefore, are not a part of plasma. Electrolytes are a part of plasma but do not have a role in blood clotting. PTS: 1 DIF: M REF: 275 KEY: UNDERSTANDING 11. ANS: C The body has two types of hematopoietic tissue: red bone marrow and lymphatic tissue. PTS: 1 DIF: M REF: 276 KEY: REMEMBERING 12. ANS: D Immature erythrocytes are called reticulocytes. A myeloblast is an offspring of a stem cell that eventually transforms into one of the three types of granulocytes. A megakaryocyte creates platelets. A progranulocyte is an immature granulocyte. PTS: 1 DIF: E REF: 276 KEY: REMEMBERING 13. ANS: D Red bone marrow can be found in the ends of long bones and in flat, irregular bones in adults. This includes the pelvis as well as the sternum, cranial bones, and vertebrae. The medullary cavity is filled with yellow marrow in adults and red marrow in children. Copyright © 2020 F. A. Davis Company TESTBANKSELLER.COM  TESTBANKSELLER.COM PTS: 1 DIF: E REF: 276 KEY: REMEMBERING 14. ANS: B The oxygen-carrying component of hemoglobin contains iron; therefore, an adequate supply of dietary iron is crucial for hemoglobin synthesis. PTS: 1 DIF: M REF: 278 KEY: APPLYING 15. ANS: B Oxygen levels decline as damaged red blood cells are removed from circulation. This triggers the process of red blood cell production. PTS: 1 DIF: M REF: 279 KEY: UNDERSTANDING 16. ANS: A EPO is a hormone secreted by the kidneys in response to declining oxygen levels. In turn, EPO stimulates red bone marrow to begin production of red blood cells. None of the other answers are correct. PTS: 1 DIF: M REF: 279 KEY: UNDERSTANDING 17. ANS: C Because the atmosphere contains less oxygen at higher altitudes, the body compensates by increasing its production of red blood cells. In the process, it increases the number of reticulocytes released into circulation. A bone marrow disorder resulting in anemia would produce fewer reticulocytes. A liver disorder resulting in increased plasma proteins would not affect production of reticulocytes. PTS: 1 DIF: M REF: 279 KEY: APPLYING 18. ANS: C A blood cell normally lives for 120 days. TESTBANKSELLER.COM PTS: 1 DIF: E REF: 279 KEY: REMEMBERING 19. ANS: C Heme is broken down into iron and bilirubin. Bilirubin is excreted in the intestines as part of bile. Globin is broken down into amino acids. Erythropoietin is excreted by the kidneys in response to low oxygen levels. PTS: 1 DIF: M REF: 280 KEY: UNDERSTANDING 20. ANS: C Iron is transported to the bone marrow, where it is used to create new hemoglobin. Iron is not used in the production of new proteins, and it is not excreted in the intestines. It is also not transported to the spleen. PTS: 1 DIF: M REF: 280 KEY: UNDERSTANDING 21. ANS: D Blood contains more red blood cells than any other formed element. Basophils are a type of white blood cell. PTS: 1 DIF: E REF: 276 KEY: REMEMBERING 22. ANS: B Eosinophils are involved in allergic reactions, so an increased number indicates an allergy. Leukemia can cause increased numbers of various types of white blood cells, depending on the type of leukemia; however, eosinophils are not one of the white blood cells affected. Dehydration would not cause an elevation eosinophil count. A clotting disorder would be reflected by a decreased number of platelets. PTS: 1 DIF: M REF: 282 KEY: APPLYING 23. ANS: D Copyright © 2020 F. A. Davis Company TESTBANKSELLER.COM  TESTBANKSELLER.COM The first stage of hemostasis involves a spasm of the blood vessel, which slows the flow of blood. The activation of prothrombin, the activation of factor X, and the formation of sticky platelets all come later. PTS: 1 DIF: M REF: 285 KEY: UNDERSTANDING 24. ANS: B The exposure of collagen fibers creates a rough spot on the interior of the vessel; this rough spot triggers changes in passing platelets that transforms them into sticky platelets. The fibrin threads and the activation of factor X come after platelets become sticky platelets. The initial spasm in the blood vessel does not affect the platelets. PTS: 1 DIF: M REF: 285 KEY: UNDERSTANDING 25. ANS: D The extrinsic pathway begins when factors outside or extrinsic to the blood (such as the damaged blood vessel and surrounding tissues) release clotting factors. The skin surface does not release clotting factors. The circulating platelets do not activate clotting factors, but when the platelets begin to adhere to the collagen in the damaged vessel, they do activate clotting factors. PTS: 1 DIF: M REF: 286 KEY: UNDERSTANDING 26. ANS: A Prothrombin activator transforms prothrombin into thrombin. In turn, thrombin transforms fibrinogen into fine threads of fibrin. PTS: 1 DIF: M REF: 286 KEY: UNDERSTANDING 27. ANS: C The final step before a clot forms occurs when thrombin transforms fibrinogen into fine threads of insoluble fibrin. The fibrin threads form aTweb ESatTBtheAN KSofEthe site LLinjury ER.C inOwhich M passing blood cells become ensnared, forming a clot. Prothrombin transforms into thrombin before fibrin threads form. Platelets become sticky and accumulate at the site of injury soon after a vessel is cut; this forms a platelet plug and not a clot. Plasminogen transforms into plasmin during dissolution of the clot. PTS: 1 DIF: M REF: 286 KEY: UNDERSTANDING 28. ANS: B Vitamin K is necessary for the synthesis of clotting factors. PTS: 1 DIF: M REF: 287 KEY: REMEMBERING 29. ANS: A The ABO system identifies the type of antigen on the red blood cell. Plasma does not carry antigens; it carries antibodies. Although the type of antigen determines the type of antibodies in the plasma, the ABO system is named for the type of antigen on the red blood cell. PTS: 1 DIF: E REF: 288 KEY: UNDERSTANDING 30. ANS: C Type O blood has neither A or B antigens and both anti-A and anti-B antibodies. There is no such thing as the O antigen. PTS: 1 DIF: M REF: 288-289 KEY: ANALYZING 31. ANS: A Copyright © 2020 F. A. Davis Company TESTBANKSELLER.COM  TESTBANKSELLER.COM Rh-negative blood lacks the Rh antigen, which is found in Rh-positive blood. Anti-Rh antibodies only appear after someone with Rh-negative blood is exposed to Rh-positive blood. Most Americans have Rh-positive blood. The first time someone with Rh-negative blood is exposed to Rh-positive blood, the person's body will develop anti-Rh antibodies but no reaction will occur.
