    Red cell distribution width (RDW)
  120. This is a test that is checked primarily when a pt is anemia and should be increased in response to anemia. If it isn't, it's b/c the bone marrow can't or doesn't have what it needs to make RBCs. It's expressed as a % of total RBCs & should be about 1%.
    Reticulocyte count (retic count)

    Peripheral blood smear
  122. This is a test where you can do special stains for iron stores & make sure the precursors of RBCs are intact. It is done to confirm megaloblastic anemia and diagnose leukemia or lymphoma. If a pt is anemic, you can use this test to determine if the bone marrow is the cause, document iron stores, document infiltration of bone marrow (neoplasm or fibrosis).

  124. This disease can have symptoms from tissue hypoxia (fatigue, weakness, dyspnea, angina, HA, or faintness) and compensation mechanisms (pale skin, nail beds, mucosa, tachycardia, palpitations, cardiac flow murmur b/c of increased flow & decreased viscosity of the blood).
  125. This is an anemia due to premature destruction of RBCs.
    Anemia due to hemolysis
