10. Using the following illustration, calculate the hematocrit of the individual by using a ruler to measure the packed cell volume and the total volume of blood. Determine if it falls within normal limits. Clay/red cell interface Red cell/plasma interface Plasma/air interface Hematocrit: Within normal limits? (yes/no)

Step 1
Hematocrit is the ratio of the volume of red blood cells to the total volume of blood. It is expressed as a percentage. Normal ranges vary by age and sex, but a general reference range for adults is approximately 38.3% to 48.6% for men and 35.5% to 44.9% for Show more…

Place the following steps of the hematocrit procedure in order. Cleanse the end of the test subject's finger with an alcohol swab Prick the finger with a lancet and wipe away the first drop of blood with the alcohol swab Draw blood into a heparinized capillary tube Plug the blood end of the tube with sealing clay Place the sealed tube into a microhematocrit centrifuge and spin for 3-5 minutes

In normal blood, there are about 5.4*10^6 red blood cells per milliliter. The volume of a red blood cell is about 90.0*10^-12 cm^3, and its density is 0.96 g/mL. How many red blood cells would a 125 kg person contain, assuming that the person's volume is composed of tissues that contain this homogeneous value of red blood cells? A student wishes to convert 100 acres into square meters and performs the following incorrect calculation: 1.00 acre = 43560 ft^2 (1 ft = 12 in) (1 in = 2.54 cm). Report the units of the student's answer and correct the work such that the correct answer is obtained.
