Exam 2: From Hematopoiesis to the Complete Blood Count

The key organs involved in extramedullary hematopoiesis include the:

Bone marrow aspiration is usually required in conditions of:

A patient's hemoglobin is 12.3 g/dL.On the peripheral smear, the red cells appear normochromic, normocytic.The hematocrit value that correlates with these data is:

The hormone responsible for red blood cell development in the bone marrow is:

Correlation checks between the red blood cell count, the hemoglobin, and the hematocrit are significant parts of QA (quality assurance) in the hematology lab.These correlations are known as:

Patients with moderate anemias (7 to 10 g/dL) may be asymptomatic.

Antibody-coated red cells that have their antibodies stripped away in the spleen usually reappear in the circulation as:

Which of these assays is the best test to assess the bone marrow's response to anemic stress?

The spleen harbors _of the circulatory platelet mass.

The __is one of the most stable parameters in a CBC.

A peripheral blood smear indicator of ineffective bone marrow response is:

A patient with the following values-RBC = 4.01  10¹²/L, Hgb = 12.5 g/dL, and Hct = 37.2%-will most likely have which of the following RBC indices?

The CBC parameter that gives insight as to the amount of anisocytosis present in a specimen is:

What is the average M:E ratio for normal adult bone marrow?

Which of the following sites is the most preferable site for bone marrow aspiration and biopsy in adults?

T cells are responsible for humoral immunity.

Mature red blood cells leave the bone marrow and enter the circulation via the:

Erythropoietin is produced by the:

Opsonizing antibodies produced by the spleen serve to:

A Wright-stained smear of a patient with an elevated reticulocyte count should show:
