Let the lengths of the legs of a right triangle be 7 inches and 9 inches. Using the Pythagorean Theorem, find the length of the hypotenuse rounded to three decimal places if necessary. 

a.  Write 0.12% as a decimal number. b.  Write 3.24 as a percent. c.  Write as a percent.

A peripheral blood smear shows left-shifted neutrophils, toxic granulation, and Dohle bodies. The patient may have been admitted to the hospital for:

A CBC was performed on a patient and the results were as follows: RBC: 6.1×106/uL HGB: 8.0 g/dL HCT: 33 % MCV: 54.1 fL MCH: 13.1 pg MCHC: 24.2 % RDW: 19.1 % Which type of anemia could correspond with these results?

You ran a microhematocrit in duplicate and your average result was 38%. You then ran a CBC and found the RBC to be 4.1 x106/uL, and the HGB was 12.3 g/dL. What are the RBC indices?

List the normal maturation sequence of the erythroid precursor cells (from left to right):

A manual WBC count was performed on an EDTA-anticoagulated sample. The sample was diluted and 150 leukocytes were counted in 5 large (WBC) squares. The total calculated WBC count was 36300/uL. What was the dilution factor?

Your analyzer gave a platelet count of 71×103/uL. Because this is a low value, you decided to double check the result by scanning a slide and performing a platelet estimate. You noticed that the platelets were evenly distributed and you counted an average of 5 platelets per 100x field. What is your platelet estimate?

You ran a CBC and found the HGB was 7.2 g/dL. You then ran a microhematocrit in duplicate and your average result was 27%. What is the most likely reason that these results do not follow the rule of three? (Hint: use the rule of three to calculate the expected microhematocrit value)

The average lifespan of a normal erythrocyte is:
