On a standard reticulocyte preparation with new methylene blue, 100 cells are counted containing blue-stained granulofilamentous material. The red blood count is 3.22  1012/L, and the hematocrit is 30.
 
  Using information determined from Questions 23 through 27, what is the correct interpretation for this patient's condition?
 
  a. Microcytic anemia with inadequate bone marrow response
  b. Macrocytic anemia with adequate bone marrow response
  c. Normocytic anemia with inadequate bone marrow response
  d. Normocytic anemia with adequate bone marrow response

Question 2

On a standard reticulocyte preparation with new methylene blue, 100 cells are counted containing blue-stained granulofilamentous material. The red blood count is 3.22 x 1012/L, and the hematocrit is 30. Calculate the MCV.
 
  a. 80 fL
  b. 93 fL
  c. 98 fL
  d. 108 fL

Answer to Question 1

ANS: D
The RPI is greater than 3, which suggests an adequate bone marrow response. Because the MCV is in the reference range, the anemia is normocytic.

Answer to Question 2

ANS: B
The MCV = 30/3.22 x 10 = 93 fL.
