anemia? nea, and fatigue
2. which RBC indices measures the average mean corpuscular volume (MCV)
size of red blood cells?
3. anemia can be caused by ______, ______, excessive blood loss, impaired RBC production,
and ______. and increased RBC destruction
4. which anemia is considered a microcytic iron-deficiency anemia
anemia?
5. definition of anemia Anemia is a hematological disorder character-
ized by a reduction in the total number of circu-
lating red blood cells (RBCs) and/or a decrease
in hemoglobin (Hb) amount or function.
6. Complete blood count (CBC) compo-
nents that relate to RBCs and their pro-

7. microcytic anemia MCV<80 fL
- RBCs are small
- iron-deficiency anemia
- sideroblastic anemia
- thalassemia
- anemia of chronic disease
8. normocytic anemia MCV 80-99 fL
- RBCs are normal in size
, NR 507 Edapt Unit 2 Hematological Disorders
- anemia of inflammation and chronic disease
- hereditary spherocytosis
- G6PD deficiency
- paroxysmal nocturnal hemoglobinuria
9. macrocytic anemia MCV > 100 fL
- RBCs are large
- B12 deficiency (pernicious anemia)
- folate deficiency
10. hypochromic anemia low MCHC
- RBCs have less hemoglobin than normal
- RBCs appear pale in color
11. normochromic normal MCHC
- RBCs have a normal amount of hemoglobin
- RBCs appear neither pale nor dark
12. hyperchromic high MCHC
- RBCs have more hemoglobin than normal
- RBCs appear a deeper hue of red than normal
13. clinical manifestations of anemia - severe fatigue
- pallor
- weakness
- dyspnea
- dizziness
Furthermore, the reduction in RBC level will de-
crease blood volume, activating the renin-an-
giotensin-aldosterone (RAA) system, which pro-

crease plasma volume, but also dilute the plas-

creates a hyperdynamic state. This "stresses" the
cardiac system and can result in tachycardia or
even heart failure.
