Calculate the number of RBC per 1 mm3. The volume of 1R is 0.004 mm3, the RBC count in 5R equals to 250, and the dilution factor is 1:200

The average diameter of  a RBC is 7.2micrometer and average diameter of spherical RBC is 6.7micrometer. The normal RBC has an average surface area of 136micrometer^2 and volume of 91micrometer^3. Without a calculator how do you estimate the surface area to volume ratio for the spherical RBC?

Given a retic count of 6.5%. Calculate the corrected retic count and RPI.  The RBC count is 2.90 x 10^6/ul, Hct = 34.0% using the RBCcount as standard

Order: IV 0.9% NS 500mL bolus over 4hrs. If you start this bolus IV at 1730h on an infusion pump, how much will be left in the bag at 1900h change of shift? Paragraph B I + v Insert Stuff

Why do you hold the pipet in a nearly horizontal position during dilution? What are the factors that may affect the accuracy of dilutions made with blood diluting pipets? List down the expected errors that can be encountered in the blood dilution method. What is the dilution factor if the blood is sucked to 0.4 mark of RBC pipet?
