|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



poisoning. MCV <80 |\ |\




Normocytic anemia - CORRECT ANSWERS ✔✔due to hemorrhage
|\ |\ |\ |\ |\ |\ |\ |\



or chronic disease. Aplastic anemia. MVC 80-92
|\ |\ |\ |\ |\ |\




macrocytic anemia - CORRECT ANSWERS ✔✔due to folate or
|\ |\ |\ |\ |\ |\ |\ |\ |\



vitamin B12(cobalamin) deficiency (megaloblastic anemia) /
|\ |\ |\ |\ |\ |\



pernicious anemia. /liver diseases
|\ |\ |\




serum ferritin - CORRECT ANSWERS ✔✔Tests for iron stores. As
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



serum ferritin falls, TIBC rises, and serum iron levels will
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



eventually fall. |\




Anemia of chronic disease - CORRECT ANSWERS ✔✔NORMOcytic
|\ |\ |\ |\ |\ |\ |\ |\



anemia with ↓ serum iron, ↓ TIBC, and normal iron stores. Treat
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



with epoetin and give an iron supplement
|\ |\ |\ |\ |\ |\




Schistocytes - CORRECT ANSWERS ✔✔Associated with hemolytic
|\ |\ |\ |\ |\ |\ |\



uremia syndrome |\

,pernicious anemia - CORRECT ANSWERS ✔✔Macrocytic anemia
|\ |\ |\ |\ |\ |\ |\

|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



of erythrocytes - low levels will cause the RBC to expand. PPIs
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



and histamine2 blockers can cause this.
|\ |\ |\ |\ |\

, TIBC (total iron binding capacity) - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\



✔✔Available transferrin that is left unbound (Represents the
