Question

5. A goat on the farm has been diagnosed with a parasite. Karen collects a sample of 600 ml of blood from the goat. The packed red blood cell volume of the collected blood is 35%.

a. How many milliliters of packed red blood cells did Karen collect? (2 points)
b. How many milliliters of the sample remains as blood plasma? (2 points)
c. Identify the conversion factor for milliliters to ounces. (1 point)
d. How many ounces of packed red blood cells did Karen collect? (2 points)

Answer 1

below

Explanation:

a. To calculate the number of milliliters of packed red blood cells collected by Karen, we need to determine 35% of the total blood volume.

Packed red blood cell volume = Total blood volume * Percentage of packed red blood cells

Given that the packed red blood cell volume is 35% and the total blood volume collected is 600 ml, we can calculate the packed red blood cell volume as follows:

Packed red blood cell volume = 600 ml * 0.35 = 210 ml

Therefore, Karen collected 210 milliliters of packed red blood cells.

b. To find out how many milliliters of the sample remain as blood plasma, we need to subtract the packed red blood cell volume from the total blood volume.

Blood plasma volume = Total blood volume - Packed red blood cell volume

Blood plasma volume = 600 ml - 210 ml = 390 ml

Thus, 390 milliliters of the sample remain as blood plasma.

c. The conversion factor for milliliters to ounces is 1 ml = 0.0338 ounces.

d. To calculate the number of ounces of packed red blood cells collected, we can convert the volume from milliliters to ounces using the conversion factor.

Ounces of packed red blood cells = Packed red blood cell volume (ml) * Conversion factor (ml to ounces)

Ounces of packed red blood cells = 210 ml * 0.0338 ounces/ml = 7.098 ounces

Therefore, Karen collected approximately 7.098 ounces of packed red blood cells.
