Anemia
Anemia ( 15 Questions)
Select all the types of anemia that are characterized by RBCs that are smaller than normal.
Microcytic anemia is characterized by red blood cells (RBCs) that are smaller than normal. This can occur in conditions like iron-deficiency anemia and thalassemia, where there is impaired hemoglobin production or insufficient iron for RBC formation.
Normocytic anemia is characterized by RBCs that are of normal size. This can occur in various conditions, including chronic diseases like chronic kidney disease and some types of anemia of chronic inflammation.
Macrocytic anemia is characterized by RBCs that are larger than normal. This can be seen in conditions like megaloblastic anemia, which is often caused by vitamin B12 or folate deficiency.
Anisocytosis refers to a condition where RBCs are of unequal sizes. While it is not a specific type of anemia, anisocytosis can be seen in various types of anemia, including iron-deficiency anemia, as RBCs may vary in size due to different stages of development.
Poikilocytosis refers to a condition where RBCs have abnormal shapes. Like anisocytosis, poikilocytosis is not a specific type of anemia but can be observed in various anemias, including sickle cell anemia, where RBCs take on a characteristic crescent shape.
Choice A rationale:
Microcytic anemia is characterized by red blood cells (RBCs) that are smaller than normal.
This can occur in conditions like iron-deficiency anemia and thalassemia, where there is impaired hemoglobin production or insufficient iron for RBC formation.
Choice B rationale:
Normocytic anemia is characterized by RBCs that are of normal size.
This can occur in various conditions, including chronic diseases like chronic kidney disease and some types of anemia of chronic inflammation.
Choice C rationale:
Macrocytic anemia is characterized by RBCs that are larger than normal.
This can be seen in conditions like megaloblastic anemia, which is often caused by vitamin B12 or folate deficiency.
Choice D rationale:
Anisocytosis refers to a condition where RBCs are of unequal sizes.
While it is not a specific type of anemia, anisocytosis can be seen in various types of anemia, including iron-deficiency anemia, as RBCs may vary in size due to different stages of development.
Choice E rationale:
Poikilocytosis refers to a condition where RBCs have abnormal shapes.
Like anisocytosis, poikilocytosis is not a specific type of anemia but can be observed in various anemias, including sickle cell anemia, where RBCs take on a characteristic crescent shape.
