NR 507 EDAPT UNIT 2 HEMATOLOGICAL DISORDERS EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS 100% PASS (A+ CERTIFIED) 1. what are four clinical characteristics of anemia Correct Answer tachycardia (due to hypoxemia), pallor, dyspnea, and fatigue 2. which RBC indices measures the average size of red blood cells Correct Answer mean corpuscular volume (MCV) 3. anemia can be caused by ______, ______, and ______ Correct Answer excessive blood loss, impaired RBC production, and increased RBC destruction 4. which anemia is considered a microcytic anemia Correct Answer iron-deficiency anemia 5. definition of anemia Correct Answer Anemia is a hematological disorder characterized by a reduction in the total number of circulating red blood cells (RBCs) and/or a decrease in hemoglobin (Hb) amount or function. 6. Complete blood count (CBC) components that relate to RBCs and their production Correct Answer 7. microcytic anemia Correct Answer MCV80 fL - RBCs are small - iron-deficiency anemia - sideroblastic anemia - thalassemia - anemia of chronic disease 8. normocytic anemia Correct Answer MCV 80-99 fL - RBCs are normal in size - anemia of inflammation and chronic disease - hereditary spherocytosis - G6PD deficiency - paroxysmal nocturnal hemoglobinuria 9. macrocytic anemia Correct Answer MCV 100 fL - RBCs are large - B12 deficiency (pernicious anemia) - folate deficiency 10. hypochromic anemia Correct Answer low MCHC - RBCs have less hemoglobin than normal - RBCs appear pale in color 11. normochromic Correct Answer normal MCHC - RBCs have a normal amount of hemoglobin - RBCs appear neither pale nor dark 12. hyperchromic Correct Answer high MCHC - RBCs have more hemoglobin than normal - RBCs appear a deeper hue of red than normal 13. clinical manifestations of anemia Correct Answer - severe fatigue - pallor - weakness - dyspnea - dizziness Furthermore, the reduction in RBC level will decrease blood volume, activating the renin-angiotensin-aldosterone (RAA) system, which promotes fluid retention and movement of interstitial fluid into the capillaries. This will not only increase plasma volume, but also dilute the plasma further. The dilute blood flows faster, which creates a hyperdynamic state. This "stresses" the cardiac system and can result in tachycardia or even heart failure. 14. the terms normocytic, microcytic, and macrocytic characterizes red blood cells by their _______ Correct Answer size Terms that end with "-cytic" refer to cell size. 15. what symptoms reflect decreased tissue oxygenation as an effect of anemia Correct Answer weakness, hypertension, fever, dizziness, and dyspnea 16. true or false Correct Answer identification of the type of anemia involves an exemption of size of the red blood cell only Correct Answer false Determining both the size and color of RBCs is an important step in identifying the type and source of anemia. 17. which anemia is a type of macrocytic anemia Cor
