Question | Answer |

Painful swelling of hands and feet caused by sickle cell in the microcirculation of sickle cell infants is | dactylitis |
a patient with sickle cell anemia may develop cardiopulmonary disease due to | increased blood viscosity |
the hemolytic anemias are generally classified morphologically as | normocytic normochromic |
The hemoglobin that cannot be separated from Hgb S through electrophoresis in buffer at pH 8.6 is | Hgb D pungab, Hgb G philia |
Autosplenectomy is characteristic of | Sickle cell |
The hemoglobin variant that is seen frequently in the southeastern population, shows a microcytic picture and migrates with Hgb C at 8.6 is | Hgb E |
Which of the following "poikilocytes " is classically associated with hemoglobinopathies and liver disease? | target cells |
Cholelithasis is frequent complication of patients with hereditary spherocytosis because | increased bilirubin is a frequent finding to continued hemolysis |
Spherocytes do not function well in the splenic environment because | equilibrium is off (spherocytes have too much sodium, and the spleens environment has a low pH, low ATP, and low glucose) |
One of the gravest clinical problems for individuals with thalassemia major is | Iron overload |
The RBC inclusions that are composed of denatured hemoglobin are called | Heinz bodies |
Which of the following morphological features is classic in the megaloblastic anemias | macro ovalocytes (hypersegmented nutrophils) |
Spherocytes differ from normal cells in all of the following ways | no central pallor (less stretching, ATP disrupted, accumulate sodium @ a faster rate) |
An appropriate M:E ratio in the case of megaloblastic anemia would be | 1:1 to 1:3 |
Individuals with fanconi's anemia characteristically show | Structure abnormalities of the kidney, Chromosomal abnormalities, defective DNA repair, causing short stature, hyper-pigmentation on the trunk and neck, and broad nose |
Ineffective erythropoeisis is defined as | destruction in the bone marrow of RBC precursors before they reach the peripheral circulation |
Red cells that are resistant to malaria, rigid, and spoon shaped | Southeastern ovalocytosis |
On electrophoresis, the majority hemoglobin for individuals with thalassemia major is | Hgb F |
One of the least severe clinical manifestations of G6PD defenciency is | Congenital nonspherosytic hemolytic anemia (CNHA) |
Storage iron is usually determined by the | serum ferritin (can be tested at all 3 stages) |
Failure to thrive, bossed skull, severe anemia, and splenomegaly are all symptoms of which of the following disorders | beta thalassemia major state |
The alpha thalassemic condition that is incompatible with life is | Barts Hydrob fetalis |
The first stage of iron deficiency anemia is termed | stage 1: Continuum of iron depletion from the marrow |
Which inclusion is associated with a "pitted" golf ball appearance | Hgb H |
