Question 1

Hemorrhagic Anemia

Answer 1

results from severe blood loss. RBCs are otherwise normal in size and amount of hemoglobin.

Question 2

Aplastic Anemia

Answer 2

Bone marrow is not producing many new RBCs: Reticulocytes (immature red blood cells) in blood are very low. The circulating RBCs are normal, but the total count, hematocrit and hemoglobin levels are low.

Question 3

Iron Deficiency Anemia

Answer 3

RBCs cannot make adequate hemoglobin without iron. RBCs are small. Hematocrit, hemoglobin, MCV and MCH are all low.

Question 4

Pernicious anemia

Answer 4

maturation of RBCs cannot occur without adequate vitamin B12. RBC production declines and cells become larger and misshapen

Question 5

Hemolytic anemia

Answer 5

RBCs are breaking down in the bloodstream. Hemoglobin and hematocrit levels are low. Immature RBC levels are very high. Individual RBCs are typically normal.

Question 6

Hemoglobin S

Answer 6

mutant hemoglobin in Sickle Cell Disease
sticky- tend to stick in capillaries (diminishes blood supply)
RBCs can rupture and leads to low RBC counts.
